The present disclosure relates generally to probe cards for probe systems and more specifically to customizable probe cards with probes configured to be selectively repositioned on the customizable probe cards.
Probe systems may be utilized to test the operation of a device under test (DUT). In specific examples, the DUT may include a semiconductor device, and the probe system may be configured to electrically test the operation of the DUT, such as by providing a test signal to the DUT and/or by receiving a resultant signal from the DUT.
In some configurations, the probe systems utilize a probe card that includes one or more probes for testing the DUT, with the probe card being configured to be selectively and repeatedly installed on and removed from a probe card holder of the probe system. In this manner, the probe systems may be reconfigured for testing differently configured DUTs by selectively installing a probe card with probes that are specifically configured and/or arranged for testing a given DUT. However, replacing the probe cards in this manner may incur undesired downtime and/or monetary expenses. In addition, each probe card may be custom-made for a given DUT, thereby increasing operational costs and/or lead time associated with designing, manufacturing, and/or obtaining an appropriate probe card for a given DUT. Thus, there exists a need for customizable probe cards.
Customizable probe cards, probe systems including the same, and related methods are disclosed herein. A customizable probe card for testing one or more devices under test (DUTs) includes a support structure, one or more probe assemblies supporting respective probes and operatively coupled to the support structure, and a probe repositioning assembly. The probe repositioning assembly is configured to facilitate selective adjustment of an orientation of the respective probe of at least one probe assembly of the one or more probe assemblies relative to the support structure. The customizable probe card is configured to be selectively reconfigured for operative use with each of a plurality of distinct DUTs by selectively repositioning the respective probe of at least one probe assembly of the one or more probe assemblies relative to the support structure.
In some examples, a probe system comprises a chuck with a chuck support surface configured to support a substrate that includes one or more DUTs, a customizable probe card configured to test the one or more DUTs, and a probe card holder configured to support the customizable probe card relative to the substrate.
In some examples, a method of reconfiguring a customizable probe card with at least one probe assembly comprises utilizing a probe repositioning assembly to reposition a respective probe of at least one probe assembly. In some such examples, the customizable probe card is configured to be selectively reconfigured for operative use with each of a plurality of distinct DUTs by selectively repositioning the respective probe of at least one probe assembly relative to a support structure. In some such examples, each DUT includes one or more testing locations, and the respective probe of each probe assembly of the customizable probe card is configured to interface with a respective testing location of the respective DUT to test the respective DUT. In such examples, the repositioning the respective probe of the at least one probe assembly includes bringing the respective probe of each probe assembly of the at least one probe assembly to a respective orientation that corresponds to a configuration of one of the one or more testing locations.
Substrate 40 may include and/or be any suitable structure that may support, include, and/or have formed thereon DUT 42. Examples of substrate 40 include a wafer, a semiconductor wafer, a silicon wafer, a gallium nitride wafer, and/or a gallium arsenide wafer. Similarly, DUT 42 may include and/or be any suitable structure that may be probed and/or tested by probe system 10. As examples, DUT 42 may include a semiconductor device, an electronic device, an optical device, an optoelectronic device, a logic device, a power device, a switching device, and/or a transistor.
Conventional probe systems may utilize a conventional probe card that includes one or more probes for testing one or more corresponding DUTs. Such conventional probe cards generally are configured such that a spatial orientation and/or configuration of the probe(s) attached thereto is fixed and corresponds to a spatial orientation and/or configuration of the corresponding DUT(s) formed on the substrate. However, such probe cards may require replacement in order for the corresponding probe system to be utilized to test substrates and/or DUTs that are differently configured.
To mitigate such inefficiency and/or expense, customizable probe cards 100 according to the present disclosure are configured to facilitate reconfiguration of probes 130 such that the customizable probe card may be utilized with any of a plurality of differently configured substrates and/or DUTs. For example, and as discussed in more detail herein,

In some examples, and as schematically illustrated in
As used herein, the terms “operative use,” “operatively utilized,” and the like, as used to describe a configuration in which probe system 10 and/or customizable probe card 100 operates to test substrate 40 and/or DUT(s) 42, generally relate to examples in which the probe system supports the substrate and the customizable probe card is operable to test at least one DUT on the substrate. For example, probe system 10 and/or customizable probe card 100 may be described as being in operative use when at least one probe 130 of the customizable probe card is positioned to engage and/or interface with a respective testing location 44 for testing a corresponding DUT 42, is configured to provide test signal 72 to the testing location, and/or is configured to receive resultant signal 74 from the testing location. However, such descriptions are not limiting with respect to the structures and components described herein, and it is to be understood that the structures and components disclosed herein do not require that customizable probe card 100 always be in operative use and/or operatively positioned relative to substrate 40 and/or DUT(s) 42.
Each probe 130 may have any appropriate form and/or structure for testing DUT 42. In particular, and as schematically illustrated in
As used herein, directional terms such as “horizontal,” “vertical,” and the like generally refer to a configuration in which substrate 40 extends at least substantially parallel to the ground and in which customizable probe card 100 is positioned vertically above the substrate. Similarly, as used herein, positional terms such as “above,” “over,” “below,” “underneath,” and the like generally refer to relative positions along a vertical direction, such as along the Z-direction that is illustrated in
Customizable probe card 100 may be configured to interface with testing locations 44 in any of a variety of forms. As examples, each testing location 44 may include and/or be a contact pad, a solder bump, an optical coupler, etc. In some examples, each probe 130 has a form corresponding to a form of each testing location 44. As an example, probe 130 may be a vertical probe, such as may be configured to contact a respective testing location 44 in the form of a solder bump of a corresponding DUT 42. As another example, and as schematically illustrated in
In some examples, and as schematically illustrated in
As schematically illustrated in
As described in more detail herein, probe repositioning assembly 104 is configured to facilitate selective adjustment of a relative position and/or orientation of the respective probe 130 of at least one probe assembly 120 relative to support structure 110. In this manner, customizable probe card 100 may be selectively reconfigured for operative use with distinct substrates 40 and/or distinct DUTs 42 by selectively repositioning the respective probe 130 of at least one probe assembly 120 relative to support structure 110. Stated differently, customizable probe card 100 may be configured to be utilized to test DUTs 42 (e.g., individual DUTs 42 and/or substrates 40 including corresponding pluralities of DUTs 42) with corresponding testing locations 44 that differ in position and/or orientation (e.g., with respect to support structure 110) by selectively repositioning one or more probes 130 to conform to the configuration of testing locations 44. In this manner, customizable probe card 100 may be selectively configured and utilized to test DUTs with any of a plurality of distinct forms and/or distributions of testing locations 44 without necessitating a corresponding plurality of distinct conventional probe cards.
As described in more detail herein, probe repositioning assembly 104 may form a portion of, and/or be at least partially defined by, each probe assembly 120. As a more specific example, and as schematically illustrated in
As schematically illustrated in
In various examples, and as described in more detail herein, probe repositioning assembly 104 and/or the respective probe repositioning mechanism 106 of at least one probe assembly 120 is configured to facilitate selectively repositioning at least one probe assembly 120 and/or the respective probe holder 140 thereof relative to support structure 110 to selectively reposition the respective probe(s) 130 relative to the support structure. In some examples, and as schematically illustrated in
In some examples, the respective probe holder 140 and/or the respective probe translation stage 150 of at least one probe assembly 120 are configured to be selectively removed from support structure 110. As a more specific example, the respective probe translation stage 150 of at least one probe assembly 120 may be configured to be selectively and repeatedly operatively coupled to and uncoupled from support structure 110 without damage to the respective probe translation stage. Additionally or alternatively, the respective probe holder 140 and/or the respective probe translation stage 150 of at least one probe assembly 120 may be configured such that the respective probe holder may be selectively and repeatedly operatively coupled to and uncoupled from the respective probe translation stage.
Each probe translation stage 150 may be configured to move the respective probe holder 140 and/or the respective probe 130 relative to support structure 110 in any of a variety of manners, such as by selectively translating and/or selectively rotating the respective probe holder and/or the respective probe relative to support structure 110. As examples, each probe translation stage 150 may be configured to translate the respective probe holder 140 and/or the respective probe 130 relative to support structure 110 along one or more linear dimensions. More specifically, such linear dimensions may include one or more linear dimensions that extend at least substantially parallel to normal axis 116 and/or one or more linear dimensions that extend at least substantially perpendicular to the normal axis. Additionally or alternatively, each probe translation stage 150 may be configured to rotate the respective probe holder and/or the respective probe relative to the support structure 110, such as about an axis that is at least substantially parallel to normal axis 116 and/or about an axis that is at least substantially perpendicular to the normal axis. In this manner, each probe translation stage 150 may be utilized to operatively translate the respective probe 130 throughout the probe range of motion, thereby operatively translating each probe relative to substrate 40 and/or DUT(s) 42. In some examples, the respective probe translation stages 150 of each probe assembly 120 collectively may be utilized to operatively align the respective probes 130 with specific, target, and/or desired testing locations 44 on substrate 40 and/or on DUT 42, such as to permit communication between the respective probes and the substrate and/or DUT. This may include operative translation of each respective probe 130 in a plurality of different, separate, distinct, perpendicular, and/or orthogonal directions, such as the X-, Y-, and/or Z-directions that are illustrated in
Each probe translation stage 150 may include and/or be any suitable structure that may be operatively attached to the respective probe holder 140 and/or the respective probe 130, and/or that may be configured to operatively translate and/or rotate the respective probe 130 throughout the probe range-of-motion, such as may extend in three orthogonal, or at least substantially orthogonal, axes, such as the X-, Y-, and Z-axes of
In some examples, the respective probe translation stage 150 of at least one probe assembly 120 may include and/or be a manually actuated stage, such as a stage that is configured to move the respective probe 130 via manual adjustment of one or more actuators. Additionally or alternatively, the respective probe translation stage 150 of at least one probe assembly 120 may include and/or be a motorized, automated, or electrically actuated stage.
In an example in which probe translation stage 150 is a motorized stage, the probe translation stage may be controlled in any of a variety of manners. For example, and as schematically illustrated in
In some such examples, and as schematically illustrated in
In some examples, controller 80 may be associated with, and/or a component of, signal generation and analysis assembly 70 of probe system 10. That is, while
Signal generation and analysis assembly 70 and/or controller 80 each may be any suitable device or devices that are configured to perform the functions of the controller discussed herein. For example, the signal generation and analysis assembly and/or the controller each may include one or more of an electronic controller, a dedicated controller, a special-purpose controller, a personal computer, a special-purpose computer, a display device, a logic device, a memory device, and/or a memory device having non-transitory computer readable media suitable for storing computer-executable instructions for implementing aspects of systems and/or methods according to the present disclosure.
Additionally or alternatively, signal generation and analysis assembly 70 and/or controller 80 each may include, or be configured to read, non-transitory computer readable storage, or memory, media suitable for storing computer-executable instructions, or software, for implementing methods or steps of methods according to the present disclosure. Examples of such media include CD-ROMs, disks, hard drives, flash memory, etc. As used herein, storage, or memory, devices and media having computer-executable instructions as well as computer-implemented methods and other methods according to the present disclosure are considered to be within the scope of subject matter deemed patentable in accordance with Section 101 of Title 35 of the United States Code.
Signal generation and analysis assembly 70 additionally or alternatively may include and/or be any suitable structure that may, or that may be configured to, generate test signal 72, transmit test signal 72, receive resultant signal 74, and/or analyze resultant signal 74. Examples of signal generation and analysis assembly 70 include a signal generator, an electric signal generator, an optical signal generator, a wireless signal generator, an electromagnetic signal generator, a signal detector, an electric signal detector, an optical signal detector, a wireless signal detector, and/or an electromagnetic signal detector.
While the foregoing discussion generally relates to examples in which each probe 130 is repositionable within a range of motion of the respective probe translation stages 150, it is additionally within the scope of the present disclosure that each probe 130 may be selectively repositioned independent of a probe translation stage and/or beyond a range of motion thereof. For example, customizable probe card 100 may be configured such that the respective probe 130 of at least one probe assembly 120 may be selectively repositioned relative to support structure 110 via selective placement of the associated probe assembly 120 and/or the respective probe holder 140 thereof relative to support structure 110, such as by selectively repositioning a location at which the probe assembly and/or the respective probe holder is operatively coupled to and/or supported by the support structure. As a more specific example, and as schematically illustrated in
In some examples, probe repositioning assembly 104 may be described as including and/or being the respective probe assembly mounting structure 160 of each probe assembly 120. Similarly, in some examples, the respective probe repositioning mechanism 106 of each probe assembly 120 may include and/or be the respective probe assembly mounting structure 160 of the probe assembly.
While
Each probe assembly mounting structure 160 may be selectively and operatively retained in position relative to support structure 110 in any appropriate manner. As examples, each probe assembly mounting structure 160 may be configured to be selectively retained in position relative to support structure 110 via a magnetic force, a mechanical force, and/or a suction force, such as a suction force produced by applying a vacuum (e.g., at least substantially evacuating of air) to an interface region between the probe assembly mounting structure and the support structure.
In some examples, and as schematically illustrated in
In some examples, magnetic plate 114 is at least substantially fixed relative to support structure 110 and/or fixedly coupled to the support structure. While
In some examples, the respective probe assembly mounting structure 160 of at least one probe assembly 120 may be configured to be selectively magnetically coupled to magnetic plate 114 via a variable magnetic force. As a more specific example, magnetic plate 114 and/or the respective probe assembly mounting structure 160 of at least one probe assembly 120 may include and/or be an electromagnet that is configured to be selectively magnetized to selectively fix the respective probe assembly mounting structure in position relative to the magnetic plate during operative use of customizable probe card 100. In such examples, the electromagnet may be selectively demagnetized to permit the respective probe assembly mounting structure to be selectively repositioned relative to the magnetic plate. In some examples, and as schematically illustrated in
In some examples, and as schematically illustrated in
In some examples, probe assembly mounting structure 160 may be configured to be magnetically coupled to magnetic plate 114 and to be selectively moved relative to the magnetic plate by introducing a pressurized gas between the probe assembly mounting structure and the magnetic plate. More specifically, and as schematically illustrated in
As schematically illustrated in
In some such examples, and as schematically illustrated in
In other examples, and as discussed, probe assembly mounting structure 160 may be configured to be selectively retained in position relative to support structure 110 via a suction force. In some such examples, and as schematically illustrated in
Accordingly, in such examples, vacuum source 68 may be configured to selectively apply a vacuum to the interface region between probe assembly mounting structure 160 and support structure 110 (and/or between probe assembly mounting structure 160 and magnetic plate 114) by drawing air through gas conduit 64, thereby selectively retaining the probe assembly mounting structure relative to the support structure via a suction force. In such examples, valve 65 may be configured to selectively fluidly connect vacuum source 68 to probe assembly mounting structure 160, support structure 110, and/or magnetic plate 114 to selectively retain the probe assembly mounting structure relative to the support structure.
The foregoing examples generally correspond to examples in which a force (e.g., a magnetic force and/or a suction force) retaining probe assembly mounting structure 160 relative to support structure 110 and/or magnetic plate 114 may be selectively reduced, mitigated, and/or opposed to facilitate selectively repositioning the probe assembly mounting structure relative to the support structure. However, this is not required of all examples of customizable probe card 100, and it is additionally within the scope of the present disclosure that probe assembly mounting structure 160 may be configured to be selectively repositioned relative to support structure 110 without diminishing and/or counteracting a force that retains the probe assembly mounting structure relative to the support structure. For example, in an example in which probe assembly mounting structure 160 is retained in position relative to magnetic plate 114 via a magnetic force, the probe assembly mounting structure may be configured to be selectively translated relative to the magnetic plate while the probe assembly mounting structure is operatively magnetically coupled to the magnetic plate. More specifically, in such examples, the magnitude of the attractive magnetic force that retains the probe assembly mounting structure against the magnetic plate may be sufficiently strong to retain the probe assembly mounting structure in a static position during operative use of customizable probe card 100. In such examples, the magnitude of the attractive magnetic force also may be sufficiently weak to enable the probe assembly mounting structure to be selectively translated relative to the magnetic plate, such as along a surface of the magnetic plate, along a surface of support structure 110, and/or along a direction at least substantially perpendicular to normal axis 116, while the probe assembly mounting structure remains operatively magnetically coupled to the magnetic plate.
The foregoing examples generally correspond to examples in which probe assembly mounting structure 160 enables selectively repositioning the respective probe 130 and/or the respective probe holder 140 relative to support structure 110 along a direction at least substantially perpendicular to normal axis 116, such as by moving the probe assembly mounting structure 160 along a surface of the support structure and/or of magnetic plate 114. In some examples, probe assembly mounting structure 160 additionally or alternatively may be configured to enable repositioning the respective probe 130 and/or the respective probe holder 140 relative to support structure 110 along a direction at least substantially parallel to normal axis 116, such as by selectively translating the respective probe holder relative to the probe assembly mounting structure. As a more specific example, the respective probe holder 140 of at least one probe assembly 120 may be operatively coupled to the respective probe assembly mounting structure 160 at least partially via a magnetic force in a manner that enables and/or facilitates selectively translating the respective probe holder relative to the respective probe assembly mounting structure. In some such examples, one or both of the respective probe holder 140 and the respective probe assembly mounting structure 160 includes and/or is a magnetized material, a ferromagnetic material, and/or a permanent magnet.
As a more specific example, and as schematically illustrated in
In an example in which probe repositioning assembly 104 includes probe assembly mounting structure(s) 160, each probe assembly mounting structure may be selectively positioned upon support structure 110, and/or repositioned relative to the support structure, in any appropriate manner. As an example, the respective probe assembly mounting structure 160 of at least one probe assembly 120 may be configured to be manually repositioned relative to support structure 110.
Additionally or alternatively, in some examples, and as schematically illustrated in
In some examples, support structure 110, magnetic plate 114, and/or the respective probe assembly mounting structure 160 of at least one probe assembly 120 may be configured such that the location of each probe assembly mounting structure upon the support structure and/or the magnetic plate is continuously and/or infinitely variable. For example, the respective probe assembly mounting structure 160 of at least one probe assembly 120 may be configured to be magnetically coupled to magnetic plate 114 at any of a continuous plurality and/or distribution of locations and/or rotational configurations relative to the magnetic plate. In this manner, the position and/or configuration of the probe assembly mounting structure relative to the magnetic plate and/or the support structure may be described as being infinitely adjustable.
In some examples, customizable probe card 100 is configured to be selectively and repeatedly operatively coupled to and uncoupled from one or more other components of probe system 10. For example, and as schematically illustrated in
In some examples, and as schematically illustrated in
In some examples, and as schematically illustrated in
In some examples, customizable probe card 100 includes an electrical interface 170 that is configured to transfer electrical signals between probe assembly 120 and a component of probe system 10 exterior to the customizable probe card. As more specific examples, electrical interface 170 may be configured to transfer test signal 72, resultant signal 74, stage control signal 86, and/or electromagnet control signal 94 between probe assembly 120 and signal generation and analysis assembly 70, and/or between the probe assembly and controller 80.
Electrical interface 170 may include and/or be any of a variety of suitable structures, examples of which include an electrical cable connector and/or an electrical contact. In some examples, mounting structure 112 includes electrical interface 170. In some such examples, probe card holder 60 and/or mounting structure 112 may include and/or be a socket that provides each of a mechanical coupling and an electrical coupling between customizable probe card 100 and a component of probe system 10 exterior to the customizable probe card. As a more specific example, probe card holder 60 may include and/or be a socket that is configured to selectively receive at least a portion of customizable probe card 100 such that the probe card holder supports the customizable probe card relative to substrate 40 and such that the probe card holder forms an electrical connection with the customizable probe card. Additionally or alternatively, and as schematically illustrated in
As schematically illustrated in
Customizable probe card 100 may be configured such that maximum linear dimension 102 is sufficiently small to facilitate handling of the customizable probe card by a human user, such as while selectively coupling the customizable probe card to probe card holder 60 and/or while selectively removing the customizable probe card from the probe card holder. As more specific examples, maximum linear dimension 102 may be at least 5 centimeters (cm), at least 10 cm, at least 20 cm, at least 30 cm, at least 40 cm, at most 50 cm, at most 35 cm, at most 25 cm, at most 15 cm, and/or at most 7 cm.

In some examples, and as schematically illustrated in
Each imaging device 90 may be configured to collect light along any of a variety of directions, such as a direction that is at least substantially parallel to the X-direction, the Y-direction, the Z-direction, and/or normal axis 116 as illustrated in
Probe system 10 may be configured to support substrate 40 in any appropriate manner during operative use of customizable probe card 100. In some examples, and as schematically illustrated in
In some examples, chuck translation stage 20 is configured to facilitate repositioning at least a portion of customizable probe card 100 relative to substrate 40. As examples, chuck translation stage 20 may be configured to operatively translate chuck 30 relative to customizable probe card 100 and/or to operatively rotate chuck 30 relative to the customizable probe card, such as to facilitate establishing alignment between one or more DUT(s) 42 and one or more respective probe(s) 130 to prepare probe system 10 for testing of the DUT(s). Additionally or alternatively, chuck translation stage 20 may be configured to operatively translate and/or rotate chuck 30 relative to customizable probe card 100 so as to facilitate sequential testing of a plurality of DUTs 42 by the customizable probe card, such as by moving substrate 40 relative to customizable probe card 100 such that the respective probe 130 of at least one probe assembly 120 is aligned with a different DUT and/or a different testing location 44.
Chuck translation stage 20 may be configured to translate chuck 30 and/or substrate 40 relative to customizable probe card 100 along any of a plurality of directions and/or axes, such as along a first axis and along a second axis that is perpendicular, or at least substantially perpendicular, to the first axis. The first axis and the second axis both may be parallel, or at least substantially parallel, to chuck translation stage support surface 22. For example, the first axis may be oriented in the X-direction as illustrated in

As shown in
The repositioning the probe(s) at 230 may include repositioning in any of a variety of circumstances and/or manners. For example, the repositioning the probe(s) at 230 may include bringing one or more probes of the customizable probe card to a selected and/or desired position, such as relative to the substrate, relative to one or more DUTs, and/or relative to one or more testing locations. In this manner, and as discussed herein, the repositioning the probe(s) at 230 may operate to configure the customizable probe card such that the absolute and/or relative positions and/or orientations of the probes and/or of respective probe tips of the probes correspond to a relative orientation of testing locations of the substrate and/or DUT(s) that will be tested.
Stated differently, the repositioning the probe(s) at 230 may include bringing the probe(s) to respective positions and/or orientations that correspond to a pattern, a layout, a configuration, etc. of testing locations to be tested by the probe(s). Additionally or alternatively, the repositioning the probe(s) at 230 may include repositioning the probe(s) to correct a misalignment of the probe(s), such as relative to one another, relative to the substrate, and/or relative to another component of the customizable probe card. Stated differently, in such examples, the repositioning the probe(s) may include repositioning to correct the position(s) and/or orientation(s) of the probe(s), such as of one or more probes that are only approximately correctly positioned. As another example, the repositioning at 230 may include replacing a probe and/or a probe assembly of the customizable probe card, such as to repair and/or replace a probe tip that is damaged and/or contaminated. Examples of testing locations that may be utilized in conjunction with methods 200 are described herein with reference to testing locations 44.
The repositioning the probe(s) at 230 may be performed in any of a variety of manners, such as in any suitable manner described herein. As an example, and as shown in
In some examples, the repositioning the probe(s) at 232 includes controlling the respective probe translation stage of at least one probe assembly at least partially remotely, such as via a stage control signal that is generated and/or transmitted via a controller. Examples of controllers and/or stage control signals are described herein with reference to controller 80 and/or stage control signal 86, respectively. Additionally, the repositioning the probe(s) at 232 may include utilizing the probe repositioning assembly and/or the probe translation stage in conjunction with any other structures and/or mechanisms discussed herein in association with probe translation stage 150.
Additionally or alternatively, and as shown in
As discussed, when present, a probe assembly mounting structure (such as probe assembly mounting structure 160 described herein) generally is configured to be selectively moved (e.g., translated and/or rotated) relative to the support structure and to be fixed in position relative to the support structure to operatively position the respective probe for testing of the DUT(s). In some examples, and as discussed herein, the probe assembly mounting structure is configured such that a force (e.g., a magnetic force and/or a suction force) that retains the probe assembly mounting structure relative to the support structure may be selectively reduced, mitigated, and/or opposed to facilitate the moving the probe assembly mounting structure(s) at 244. Accordingly, in such examples, and as shown in
In an example in which the probe repositioning assembly of the customizable probe card includes one or more probe assembly mounting structures, the repositioning the probe assembly mounting structure(s) at 240 may include utilizing the probe repositioning assembly and/or each probe assembly mounting structure in conjunction with any structures and/or mechanisms discussed herein in association with probe assembly mounting structure 160. For example, the repositioning the probe assembly mounting structure(s) at 240 may include selectively utilizing one or more structures and/or mechanisms configured for selectively retaining each probe assembly mounting structure relative to the support structure and/or for facilitating repositioning of each probe assembly mounting structure relative to the support structure. As an example, and as discussed, the probe assembly mounting structure may be configured to be operatively coupled to a magnetic plate, such as magnetic plate 114 described herein, via a magnetic force. In such an example, the uncoupling the probe assembly mounting structure(s) at 242 may include conveying a pressurized flow of gas, such as air, to the interface between the probe assembly mounting structure and the magnetic plate to at least partially urge the probe assembly mounting structure away from the magnetic plate and/or to reduce the friction between the probe assembly mounting structure and the magnetic plate.
As discussed herein, in such examples, the uncoupling the probe assembly mounting structure(s) at 242 may include generating the pressurized flow with a gas source, conveying the pressurized flow through a gas conduit to the probe assembly mounting structure and/or to the magnetic plate, and/or regulating the pressurized flow with a valve. Similarly, in such an example, the coupling the probe assembly mounting structure(s) at 246 may include restricting the pressurized flow, such as with the valve, such that the magnetic force between the probe assembly mounting structure and the magnetic plate maintains the probe assembly mounting structure in position relative to the support structure. In such examples, the regulating the pressurized flow with the valve and/or the restricting the pressurized flow with the valve may include controlling the valve remotely, such as by sending a valve control signal from the controller to the valve. Examples of such gas conduits, valves, valve control signals, and/or gas sources are described herein with reference to gas conduit 64, valve 65, valve control signal 96, and/or gas source 66, respectively.
As another example, one or both of the probe assembly mounting structure and the magnetic plate may include an electromagnet that may be selectively magnetized and demagnetized to selectively increase and decrease the magnitude of the magnetic force between the probe assembly mounting structure and the magnetic plate. In such an example, the uncoupling the probe assembly mounting structure(s) at 242 may include selectively demagnetizing the electromagnet(s) to remove the magnetic force, and/or the coupling the probe assembly mounting structure(s) at 246 may include selectively magnetizing the electromagnet(s) to apply the magnetic force. As more specific examples, the uncoupling the probe assembly mounting structure(s) at 242 and/or the coupling the probe assembly mounting structure(s) at 246 may include transmitting an electromagnet control signal, such as electromagnet control signal 94 described herein, from the controller to the electromagnet.
As another example, and as discussed, the probe assembly mounting structure may be configured to be operatively coupled to (e.g., retained against) the support structure and/or the magnetic plate via a suction force, such as a suction force produced by applying a vacuum to the interface between the probe assembly mounting structure and the support structure. Accordingly, in such examples, the coupling the probe assembly mounting structure(s) at 246 may include applying a vacuum to the interface region between the probe assembly mounting structure and the support structure (and/or between the probe assembly mounting structure and the magnetic plate) by drawing air through a gas conduit, thereby selectively retaining the probe assembly mounting structure relative to the support structure via a suction force. Similarly, in such examples, the uncoupling the probe assembly mounting structure(s) at 242 may include interrupting and/or ceasing the drawing of the air through the gas conduit, such as by restricting the flow of gas through the gas conduit with the valve, thereby reducing and/or removing the suction force retaining the probe assembly mounting structure against the support structure.
The foregoing examples generally correspond to examples in which a force (e.g., a magnetic force and/or a suction force) retaining each probe assembly mounting structure relative to the support structure and/or the magnetic plate may be selectively reduced, mitigated, and/or opposed to facilitate the moving the probe assembly mounting structure(s) at 244. However, and as discussed, this is not required of all examples of methods 200, and it is additionally within the scope of the present disclosure that the moving the probe assembly mounting structure(s) at 244 may include moving each probe assembly mounting structure while the probe assembly mounting structure remains operatively magnetically coupled to the magnetic plate.
In some examples, and as discussed, the probe repositioning assembly may include a repositioning jig, and the moving the probe assembly mounting structure(s) at 244 may include operatively engaging each probe assembly mounting structure with the repositioning jig to bring each probe assembly mounting structure to a predetermined location and/or rotational orientation relative to the support structure. Examples of such repositioning jigs are discussed herein with reference to repositioning jig 108. As discussed, in some examples, the customizable probe card is configured to be selectively and repeatedly operatively coupled to and uncoupled from a probe card holder, such as probe card holder 60 described herein. In such examples, the repositioning the probe(s) at 230 may be performed while the customizable probe card remains operatively coupled to the probe card holder and/or operatively installed within the probe system. Stated differently, customizable probe cards 100 and/or methods 200 according to the present disclosure may enable selective reconfiguration of the customizable probe card without removing the customizable probe card from the probe card holder.
However, in such examples, it may be desirable to ensure that each probe is spaced apart from the substrate prior to repositioning the probes. Accordingly, in some such examples and as shown in
The separating the probe(s) at 210 and/or the establishing the interface at 260 may include moving each probe relative to the substrate and/or relative to the corresponding DUTs in any appropriate manner, such as by moving one or more probes with respective probe repositioning mechanisms of the respective probe assemblies and/or of the probe repositioning assembly and/or by moving the substrate with a chuck translation stage. Examples of probe repositioning mechanisms are described herein with reference to probe repositioning mechanism 106, such as may include and/or be probe translation stage 150 and/or probe assembly mounting structure 160. Examples of chuck translation stages are described herein with reference to chuck translation stage 20.
In some examples, and as discussed, each probe assembly mounting structure additionally or alternatively may be configured to enable repositioning the respective probe and/or the respective probe holder relative to the support structure along a direction at least substantially parallel to the normal axis, such as by selectively translating the respective probe holder relative to the probe assembly mounting structure. Accordingly, in such examples, and as shown in
In some examples, and as further shown in
As further shown in
As used herein, the term “and/or” placed between a first entity and a second entity means one of (1) the first entity, (2) the second entity, and (3) the first entity and the second entity. Multiple entities listed with “and/or” should be construed in the same manner, i.e., “one or more” of the entities so conjoined. Other entities may optionally be present other than the entities specifically identified by the “and/or” clause, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, a reference to “A and/or B,” when used in conjunction with open-ended language such as “comprising” may refer, in one embodiment, to A only (optionally including entities other than B); in another embodiment, to B only (optionally including entities other than A); in yet another embodiment, to both A and B (optionally including other entities). These entities may refer to elements, actions, structures, steps, operations, values, and the like.
As used herein, the phrase “at least one,” in reference to a list of one or more entities should be understood to mean at least one entity selected from any one or more of the entity in the list of entities, but not necessarily including at least one of each and every entity specifically listed within the list of entities and not excluding any combinations of entities in the list of entities. This definition also allows that entities may optionally be present other than the entities specifically identified within the list of entities to which the phrase “at least one” refers, whether related or unrelated to those entities specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) may refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including entities other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including entities other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other entities). In other words, the phrases “at least one,” “one or more,” and “and/or” are open-ended expressions that are both conjunctive and disjunctive in operation. For example, each of the expressions “at least one of A, B and C,” “at least one of A, B, or C,” “one or more of A, B, and C,” “one or more of A, B, or C” and “A, B, and/or C” may mean A alone, B alone, C alone, A and B together, A and C together, B and C together, A, B and C together, and optionally any of the above in combination with at least one other entity.
As used herein the terms “adapted” and “configured” mean that the element, component, or other subject matter is designed and/or intended to perform a given function. Thus, the use of the terms “adapted” and “configured” should not be construed to mean that a given element, component, or other subject matter is simply “capable of” performing a given function but that the element, component, and/or other subject matter is specifically selected, created, implemented, utilized, programmed, and/or designed for the purpose of performing the function. It is also within the scope of the present disclosure that elements, components, and/or other recited subject matter that is recited as being adapted to perform a particular function may additionally or alternatively be described as being configured to perform that function, and vice versa.
As used herein, the phrase “at least substantially,” when modifying a degree or relationship, includes not only the recited “substantial” degree or relationship, but also the full extent of the recited degree or relationship. A substantial amount of a recited degree or relationship may include at least 75% of the recited degree or relationship. For example, a first direction that is at least substantially parallel to a second direction includes a first direction that is within an angular deviation of 22.5° relative to the second direction and also includes a first direction that is identical to the second direction.
As used herein, the terms “selective” and “selectively,” when modifying an action, movement, configuration, or other activity of one or more components or characteristics of an apparatus, mean that the specific action, movement, configuration, or other activity is a direct or indirect result of one or more dynamic processes, as described herein. The terms “selective” and “selectively” thus may characterize an activity that is a direct or indirect result of user manipulation of an aspect of, or one or more components of, the apparatus, or may characterize a process that occurs automatically, such as via the mechanisms disclosed herein.
As used herein, the phrase, “for example,” the phrase, “as an example,” and/or simply the term “example,” when used with reference to one or more components, features, details, structures, and/or embodiments according to the present disclosure, are intended to convey that the described component, feature, detail, structure, and/or embodiment is an illustrative, non-exclusive example of components, features, details, structures, and/or embodiments according to the present disclosure. Thus, the described component, feature, detail, structure, and/or embodiment is not intended to be limiting, required, or exclusive/exhaustive; and other components, features, details, structures, and/or embodiments, including structurally and/or functionally similar and/or equivalent components, features, details, structures, and/or embodiments, are also within the scope of the present disclosure.
In the event that any patents, patent applications, or other references are incorporated by reference herein and (1) define a term in a manner that is inconsistent with and/or (2) are otherwise inconsistent with, either the non-incorporated portion of the present disclosure or any of the other incorporated references, the non-incorporated portion of the present disclosure shall control, and the term or incorporated disclosure therein shall only control with respect to the reference in which the term is defined and/or the incorporated disclosure was present originally.
In the present disclosure, several of the illustrative, non-exclusive examples have been discussed and/or presented in the context of flow diagrams, or flow charts, in which the methods are shown and described as a series of blocks, or steps. Unless specifically set forth in the accompanying description, it is within the scope of the present disclosure that the order of the blocks may vary from the illustrated order in the flow diagram, including with two or more of the blocks (or steps) occurring in a different order, concurrently, and/or repeatedly. It is also within the scope of the present disclosure that the blocks, or steps, may be implemented as logic, which also may be described as implementing the blocks, or steps, as logics. In some applications, the blocks, or steps, may represent expressions and/or actions to be performed by functionally equivalent circuits or other logic devices. The illustrated blocks may, but are not required to, represent executable instructions that cause a computer, processor, and/or other logic device to respond, to perform an action, to change states, to generate an output or display, and/or to make decisions.
