DETAILED DESCRIPTION

A semiconductor fabrication (fab) room may include multiple tools each including multiple substrate processing stations (hereinafter referred to as “stations”). Each of the stations can be configured to perform, for example, a conductor etch process, a dielectric etch process or other substrate treatment. Space within a fab room is limited and thus the amount of space available to access each of the tools to perform, for example, service and/or maintenance on a station is limited. The stations of the tools may be arranged in a star-shaped pattern or a linear pattern. When in the star-shaped pattern, the stations are disposed around a centrally located wafer transfer module with a robot, which moves substrates from a load lock chamber to each of the substrate processing stations and back. Although this arrangement of stations provides some access space between stations, density of stations is less than the density of stations in the linear pattern. When in the linear pattern, the stations are disposed side-by-side to form two rows of stations; one row on each side of a wafer transfer module, which may operate at atmosphere or vacuum. Although the linear-shaped arrangement allows for more stations to be disposed within a dedicated space, the linear-shaped arrangement provides restricted access to sides of the stations.

FIGS. 1 and 2 show portions of two tools 100, 102 (one in solid lines at 100 and the other in dashed lines at 102) disposed side-by-side in a fab room. Each of tools includes two rows of stations (one row is shown for each of the tools). The stations are located adjacent to a wafer transfer module (not depicted in FIG. 1 for clarity). There is limited space between the tools 100, 102. As an example, a width W of an aisle between the tools 100, 102 may be small. This provides a minimal amount of space between the tools 100, 102 to open processing chambers of the stations and obtain access to process modules and interiors of corresponding processing chambers.

The examples set forth herein include slide and pivot assemblies for stations allowing process module bias assemblies of stations to be pulled out and pivoted away from corresponding processing chambers and to allow service or maintenance to be performed in the aisle. The slide and pivot assemblies are configured to repeatedly pull out from a fully docked state to a fully undocked state and accurately return the process module bias assemblies to same fully docked locations as when previously docked. As an example, the slide and pivot assemblies are able to return the process module bias assemblies to locations within ±25 micrometers (μm, referred to as microns) of the last fully docked state. The slide and pivot assemblies are configured to handle and compensate for the heavy loads of the process module bias assemblies. An example overall weight of a process module bias assembly and corresponding slide and pivot assembly is 300 kilograms (kg). The slide and pivot assemblies provide ease of use and ease of assembly.

The tools 100, 102 include: front opening unified pods (FOUPs) 104; an equipment front end module (EFEM) and load lock 106; stations with radio frequency generators 107 and gas boxes 108; and a power lock out and tag out system 110. The stations further include process module bias assemblies 112, which include respective slide and pivot assemblies, examples of which and corresponding portions thereof are shown in FIGS. 4-30.

Each of the stations alone or in combination may be referred to as a substrate processing system. Each of the stations may be used to etch substrates using, for example, radio frequency (RF) plasma. Each station includes a processing chamber, such as an inductive coupled plasma (ICP) chamber or a conductive coupled plasma (CCP) chamber. The stations may, for example, perform conductive etch or dielectric etch processes.

FIG. 2 shows a portion of one of the tools 100, 102 of FIG. 1. The tool includes the FOUPs 104, the EFEM and load lock 106, the stations 109, and the power lock out and tag out system 110. The tool has an overall footprint 220. The tool further includes a wafer transfer module 222 for transferring substrates to and from the stations 109. The wafer transfer module 222 may include robots 224, 226 and a buffer 228 for temporary storage of wafers. The robots 224, 226 transfer wafers to and from the stations 109 and the buffer 228. Although positioned between robot 224 and robot 226 in FIG. 2, buffer 228 may be positioned anywhere in wafer transfer module 222. In other embodiments, the buffer 228 may be positioned outside wafer transfer module 222 (e.g., coupled to stations 109 or load lock 106).

FIG. 3 shows a portion of one of the tools 100, 102 of FIG. 1. The tool includes the FOUPs 104, the EFEM and load lock 106, the stations 109, and the power lock out and tag out system 110. The stations include the RF generators and gas boxes (collectively referred designated 300) and the process module bias assemblies with slide and pivot assemblies 112. The RF generators may provide RF power to electrodes in substrate supports of the stations. The gas boxes supply gases to processing chambers of the stations. The wafer transfer module 222 is also shown.

Substrates scheduled to be loaded and processed are stored in the FOUP 104. The substrates are transferred from the FOUP 104 to the stations 109 via the EFEM and load lock 106 via respective loading ports 302. The RF generators and gas boxes 300 are arranged above the stations 109 and supply RF power and process gases to process modules of the stations 109.

FIG. 4 shows a substrate processing station 400 (including a slide and pivot assembly 402), which is an example of one of the stations 109 of FIGS. 2-3. The slide and pivot assembly 402 is connected to a processing chamber 404 and a process module bias assembly 406. The slide and pivot assembly 402 allows the process module bias assembly 406 to be pulled out away from the processing chamber 404 and pivoted up to a predetermined angle relative to a front face of the processing chamber 404. The process module bias assembly 406 includes a housing 408, a portion 410 of a process module including a process bias bowl 412. The process module may include, in addition to the process bias bowl 412, an electrostatic chuck and/or other substrate support, and a top plate assembly, examples of which are shown in FIG. 6.

The example width W of an aisle between the station 400 and an opposing station is shown to illustrate that the process module bias assembly 406 is able to be pulled out and pivoted within the aisle. This provides a clear open space 414 on a right side of the slide and pivot assembly 402 for a technician to access the process bias bowl 412 and an interior of the processing chamber 404 for service and maintenance purposes including wet cleaning. The process bias bowl 412 and an interior of the processing chamber 404 are accessed from a right side of the process module bias assembly 406 without interference. For example, no slides, rails and/or other components are in the open space 414 and/or interfere with a technician accessing the interior of processing chamber 404. Although the process module and bias assembly 406 is shown pivoting to the left, the slide and pivot assembly may be configured and mounted on the right side of the processing chamber such that the process module and bias assembly pull out and pivot to the right relative to the processing chamber.

FIGS. 5 and 6 show a substrate processing system 500 illustrating a slide and pivot assembly 502 in a fully docked state 504 and in a fully undocked state 506. The substrate processing system 500 includes a vertical arrangement of a RF generator and gas box 508, a top plate assembly 509, a processing chamber 512, and a turbo pump 513 for evacuating the processing chamber 512. The processing chamber 512 sits on a stand 510 and includes a process module bias assembly 514. The process module bias assembly 514 includes a housing 516 and a process module bias bowl 518 attached to a bias mounting plate 520 of the slide and pivot assembly 502. A portion 521 of a substrate support, such as an electrostatic chuck (ESC), is shown coupled to the process bias bowl 518. The top plate assembly 509 is shown on the processing chamber 512. The process module bias assembly 514 includes circuits for supplying RF and/or bias power to electrodes of the substrate support and/or power to heater elements of the substrate support and may include coolant channels for supplying coolant to cool the substrate support. During operation, a substrate is received from a backside of the processing chamber 512 via an access port 522 and arranged on the substrate support.

The slide and pivot assembly 502 is attached to a wall of the processing chamber 512 and is configured to hold the weight of the process module bias assembly 514, which includes the weight of the slide and pivot assembly for a total assembly mass of, for example 300 kg. The slide and pivot assembly 502 is configured to handle more than a predetermined minimum number of undocking, redocking, opening and closing cycles per year (e.g., 100 cycles per year) for a predetermined number of minimum years (e.g., 10 years). The slide and pivot assembly is configured to provide a repeatable closed and fully docked position. The slide and pivot assembly is configured to be within, for example, 25 μm of an initial closed and fully docked position each time the corresponding processing chamber is opened and then returned to a closed state. This allows for repeatable undocking and redocking without need for recalibration of parameters associated with a location of the substrate support.

FIGS. 7 and 8 show a process module bias assembly 600 illustrating a fully pulled out and non-rotated state 602 and pivot angle of rotation associated with the fully undocked state 604. The fully pulled out and non-rotated state 602 is an interim state between the fully docked and fully undocked states. The fully undocked state 604 refers to when the process module bias assembly 600 is fully rotated, such that the housing 606 and process module bias bowl 608 are fully pivoted away from the processing chamber 610. While in a fully undocked state, a technician 708 is able to access the interior of the processing chamber 610 as shown while in a standing and/or kneeling position. The process module bias assembly 600 may have a predetermined maximum slide force F1 that may have a unit of measure of pound-force (lbf) and a predetermined maximum pivot (or rotational) force F2, which may also be measured unit of measure of lbf.

FIG. 9 shows a portion 800 of a processing chamber 802 including a process module bias assembly 805 (shown in FIG. 10) having a slide and pivot assembly 806. The processing chamber 802 and the slide and pivot assembly 800 may be implemented in any of the above-stated stations and have similar aspects as any of the above-stated processing chambers and slide and pivot assemblies. The slide and pivot assembly 806 includes a slide torsion plate 808, a hinge assembly 810 and a bias mounting plate 812. A pivot lock assembly 814 is shown attached to the hinge assembly 810. The pivot lock assembly 814 as further described below locks the bias mounting plate 812 in a non-pivoted state and in a fully pivoted state. The bias mounting plate 812 has bias bowl mounting features.

The slide and pivot assembly 806 is shown in an interim pivot state between the non-pivoted state and the fully pivoted state. The slide pivot assembly 806 is shown at an 80° pivot angle relative to the front sidewall 902 of the processing chamber 802. This may be a worse case bearing load position for bearings of bearing blocks of the slide and pivot assembly 806. The bearing blocks are shown in FIG. 14. The slide torsion plate 808 handles the offset load and works in torsion to support the load. The slide torsion plate 808 provides stiffness to support the cantilevered load of the bias assembly weight, and limits deflections both in the vertical and twist directions. The resulting structure is more space efficient than a design using larger rails without a torsion plate, thus allowing for shorter spacing between processing chambers, and resulting in a smaller system footprint.

FIG. 10 shows a portion 1000 of a processing chamber 802 and the corresponding process module bias assembly 805 including the slide and pivot assembly 806 of FIG. 9. The process module bias assembly 805 includes a housing 1002. A pivot lock actuator 1004 allows the housing 1002 along with the bias mounting plate 812 to be secured to processing chamber 802, or released and pivoted away from the processing chamber 802. The bias mounting plate 812 is attached to a backside of the housing 1002. The pivot lock actuator 1004 may be a “pull-tab” that pulls a cable in a cable assembly (shown in FIG. 12) to release a pivot lock plunger of the pivot lock assembly 814. The slide and pivot assembly 806 includes a slide lock assembly 1001 with a slide lock 1003 shown in a locked state while the slide and pivot assembly 806 is in a fully docked state. A slide lock actuator 1006 allows the housing 1002 along with the bias mounting plate 812 to slide in a horizontal linear manner away from the processing chamber 802. The slide lock actuator 1006 may be a “pull-knob” that pulls a cable in a cable assembly 1008 to release a slide lock plunger of the slide lock assembly 1001. Alternatively, the slide lock plunger could be actuated by electric or pneumatic control. The pivot lock plunger of the pivot lock assembly 814 may also alternatively be actuated by electric or pneumatic control.

FIG. 11 shows a portion 1100 of the processing chamber 802 and the corresponding process module bias assembly 805 including the slide and pivot assembly 806 illustrating the slide lock 1003 locked in a fully pulled out state. The slide and pivot assembly 806 includes the slide torsion plate 808 and the hinge assembly 810. The slide lock 1003 includes a plunger 1102 and wheel 1104 that is pushed into notches (one notch 1106 is shown) in the slide torsion plate 808 for different slide lock states of the slide and pivot assembly 806. The wheel 1104 spins on a pin 1107. Process module bias assembly devices and components 1110 are disposed in the housing 1002 and may include RF sources, bias voltage sources, power sources, power cables, conductive lines, coolant lines, gas lines, etc. This may include a pull handle 1112 for pulling out the process module bias assembly 805.

FIG. 12 shows the slide and pivot assembly 806 including the slide torsion plate 808, the hinge assembly 810 and the bias mounting plate 812, but not including housing 1002. The hinge assembly 810 is released from locked states by the pivot lock actuator 1004 of the pivot lock assembly 814. The pivot lock actuator 1004 is connected to a pivot lock plunger 1210 via a cable of a cable assembly 1212.

The bias mounting plate 812 is fastened to the front of the processing chamber 802 via one or more closure fasteners (e.g., bolts or screws) 1216 (shown in FIG. 26), which extends through one or more slots or holes 1218 in the bias mounting plate 812. The closure fasteners 1216 are attached after the slide and pivot assembly 806 is returned to a closed fully retracted (or fully docked) state.

The slide and pivot assembly 806 may include a jack screw assembly 1220 including a jack screw block 1222, block fasteners 1224, and a jack screw 1226. Elements of the jack screw assembly 1220 are also shown in FIGS. 18-19. The jack screw block 1222 includes slots 1223 and slides on the block fasteners 1224 between an IN position and an OUT position. In some embodiments, the IN position is the default position. The jack screw block 1222 is shown in the IN position in FIG. 18. The block fasteners 1224 are shoulder screws, which may not clamp down the jack screw block 1222. In an embodiment, the jack screw block 1222 is free to fall under its own weight at all times. due to the weight of the jack screw block 1222. The jack screw 1226 extends through the bias mounting plate 812 and is fastened to a front wall 1225 of the processing chamber 802. While the jack screw block 1222 is in the IN position, the jack screw 1226 is able to be fastened to (or screwed into) the wall 1225 of the processing chamber 802. While in the OUT position, the jack screw 1226 is able to be CCW rotated (or partially unscrewed) to move out from the front wall 1225 and push pressure on the jack screw block 1222 to disengage one or more alignment pins, such as alignment pin 1244.

The pivot lock assembly 814 includes a block 1230, which is attached to the hinge assembly 810, the plunger 1210, a bracket 1232, and a spring 1234. The bracket 1232 holds the cable assembly 1212 for the plunger 1210 in place relative to the block 1230. A portion of the pivot lock assembly 814 is shown in FIG. 17.

The bias mounting plate 812 may include one or more holes for alignment pins. Two holes 1240, 1246 and the alignment pins 1242, 1244 are shown. An example of an alignment pin is shown in FIG. 27. The alignment pins 1242, 1244 are used to align the bias mounting plate 812 relative to the processing chamber 802 when docking the slide and pivot assembly 806. The alignment pins 1242, 1244 may be mounted on the processing chamber 802 and corresponding bushings may be mounted on the bias mounting plate 812. In one embodiment, the alignment pins 1242, 1244 are mounted on the bias mounting plate 812 and the corresponding bushings are mounted on the processing chamber 802. The jack screw 1226 may be used to move the bias mounting plate 812 ON and OFF of the alignment pins 1242, 1244. The jack screw 1226 may be tightened to, for example, insert ends of the alignment pins 1242, 1244 in the corresponding bushings in the bias mounting plate 812. The jack screw may not be torqued down, but rather simply used to engage alignment pins with corresponding bushings. The above-stated closure fasteners are used to close a gap between the bias mounting plate 812 and the processing chamber 802 after the alignment pins are inserted at least partially into the bushings via the jack screw 1226. Operation of the jack screw assembly 1220 is further described below with respect to FIGS. 18-19.

FIG. 13 shows the slide torsion plate 808 and an adjustable hinge assembly 810 for the slide and pivot assembly 806 of FIG. 9. The slide and pivot assembly 806 includes the slide torsion plate 808 and the hinge assembly 810. The slide lock actuator 1006 actuates the slide lock plunger 1102. The pivot lock actuator 1004 releases the plunger 1210 of the pivot lock assembly 814.

The hinge assembly 810 includes a slide torsion plate member 1300 and a bias mounting plate member 1302. The members 1300, 1302 (also referred to as hinge members) are “U-shaped”. The slide torsion plate member 1300 is connected to a front edge of the slide torsion plate 808 via fasteners (e.g., bolts or screws) 1304, and pivots on an alignment pin that is fixed to the torsion plate. The bias mounting plate member 1302 is attached to one end of the bias mounting plate 812 (shown in FIG. 12) via fasteners (e.g., bolts or screws) 1306 (one of which is not shown). The bias mounting plate member 1302 is attached and pivots relative to the slide torsion plate member 1300 via fasteners, such as central pivot members and/or fasteners 1308; other central pivot members are shown in FIGS. 24-25. A tilt angle of the hinge assembly 810 relative to the slide torsion plate 808 may be adjusted via fasteners (e.g., bolts or screws) 1310 (may be referred to as hinge adjustment fasteners). The tilt angle may be adjusted to compensate for sag due to the weight of the process module biasing assembly and slide and pivot assembly 806. An example sag angle is shown in FIG. 26. The bias mounting plate 812 may rotate clockwise due to the weight the process module biasing assembly and slide and pivot assembly 806 when pulled out away from the processing chamber 802. This twists the slide torsion plate 808. The fasteners 1310 may be turned in or out to rotate the bias mounting plate 812 in a CCW manner relative to a pivot point (represented by pivot point 1312 and CCW rotation arrow 1314 in FIG. 26) to compensate for the clockwise sag.

Referring now to FIGS. 12 and 14, which shows a portion 1400 of the slide torsion plate 808, a guide rail system including guide rails 1402 and bearing blocks 1404, the slide and pivot assembly 806, the pivot lock assembly 814, and the slide lock assembly 1001. The guide rails 1402 are attached to an inner side of the slide torsion plate 808. In an embodiment, the guide rails 1402 are implemented as profile ball rails. The pivot lock assembly 814 includes the pivot plunger 1210, the cable assembly 1212 and pivot lock actuator 1004. The slide lock assembly 1001 includes the slide plunger 1102, the cable assembly 1008 and slide lock actuator 1006. The bearing blocks 1404 include bearings (e.g., ball bearings) that ride in grooves 1406 of the guide rails 1402. The grooves are on both top and bottom sides of the guide rails 1402. The bearing blocks 1404 are fastened to a sidewall of a processing chamber (e.g., the processing chamber 802 of FIG. 9) via fasteners that extend through holes in the bearing blocks 1404. When actuated, the slide torsion plate 808 and guide rails 1402 are moved relative to the bearing blocks 1404.

The guide rail system has high load capacity, low friction and is able to handle a large amount of weight. The load range of the guide rail system is the same for both pulling out and retracting the slide torsion plate 808. Although the rails 1402 are shown as being mounted on the slide torsion plate 808 and the bearing blocks 1404 are shown as being mounted on a processing chamber wall, the slide torsion plate 808 may be mounted on the processing chamber wall and the bearing blocks 1404 may be mounted on the slide torsion plate 808. Mounting the bearing blocks 1404 on the processing chamber wall is done for decreasing sag, because the distances from the bearing blocks 1404 to the load center of mass decrease as the slide and pivot assembly is pushed in and closed, resulting in a shorter lever arm and reduced sag effect.

A slide stop block 1420 may be attached to the sidewall of the processing chamber 802 and limit movement of the slide torsion plate 808 along the guide rails 1402. A corresponding stopping member 1422 may be fastened to the slide torsion plate 808 and be against the slide stop block 1420 depending on the state of the slide and pivot assembly 806. The slide stop block 1420 may be in contact with the stopping member 1422 when in, for example, a fully pulled out (or open) state. An additional slide stop block and an additional stopping member may be provided for the fully docked (or closed) state. The slide stop blocks 1420 and stopping member 1422 may include dampers. Example dampers are shown as round disks 1425 in FIG. 13. Other dampers may be utilized.

FIG. 15 shows the slide torsion plate 808, guide rails 1402, bearing blocks 1404, and slide lock assembly 1001 of FIG. 9-14. The guide rails 1402 are attached to the inside of the slide torsion plate 808. The bearing blocks 1404 ride on the guide rails 1402. The slide lock assembly 1001 includes the plunger 1210 and the bracket 1232, as well as a plunger housing 1500.

FIG. 16 shows a slide lock assembly 1600, which is attached to the processing chamber 802 and is an example of the slide lock assembly 1001 of FIG. 11. The slide lock assembly 1600 includes a slide lock housing 1601, the plunger 1102 and wheel 1104 that extends into notches in the slide torsion plate 808. A bracket 1602 is attached to the housing 1601 and holds the cable assembly 1008 relative to the housing 1601.

FIG. 17 shows the pivot lock assembly 814, which is attached to the bias mounting plate member 1302 of the hinge assembly 810. The hinge assembly 810 also includes the slide torsion plate member 1300, which is attached to the slide torsion plate 808. The hinge assembly 810 includes the fastener 1308, or other central pivot member, such as a pivot shaft or pin. Two locking positions for the plunger 1210 are shown and represented by channels 1700, 1702 in a pivot block 1704 attached to the slide torsion plate member 1300. The plunger 1210 is shown in the channel 1700, which is associated with the non-rotated state. The plunger 1210 may be pulled out of the channel 1700 and the bias mounting plate member 1302 may be rotated clockwise (CW) about the fastener 1308 and the plunger 1210 may then extend into the channel 1702. The channel 1702 is associated with the open (or fully rotated) position. The bias mounting plate member 1302 pivots to a fully open position at which the pivot lock plunger 1210 engages the channel 1702, referred to as a service position. The pivot lock plunger may be actuated by a pull cable (as shown in FIG. 13), or by electric or pneumatic control.

FIGS. 18-19 show the jack screw assembly 1220 including the jack screw block 1222, block fasteners 1224, and jack screw 1226. The jack screw block 1222 includes the slots 1223 and slides on the block fasteners 1224 between the IN and OUT positions. The IN and OUT positions correspond respectively to (i) the jack screw 1226 extending through the bias mounting plate 812 and fastening to the processing chamber 802, and (ii) the jack screw 1226 being used as a jack to release the bias mounting plate 812 from the processing chamber 802. While in the IN position, the head of the jack screw 1226 is able to extend into the jack screw block 1222 further than when in the OUT position. The jack screw 1226 includes a screw head 1800, a stem 1801, a screw head wear cap 1802 and a washer 1804. The jack screw block 1222 includes a stopper 1810 for the OUT position. The screw head wear cap 1802 is pressed against the stopper 1810 when the jack screw block 1222 is in the out position and the jack screw 1226 is being used to release the alignment pins from the corresponding bushings as described above. The stopper 1810 is a solid integral portion of the jack screw block 1222 that prevents the head 1800 of the jack screw 1226 from being moved into the jack screw block 1222. The stem 1801 may be threaded and be screwed into a threaded bushing 1812 inserted in the processing chamber wall 1814. Another jack screw assembly example is further shown in FIGS. 44-46. In an alternative embodiment, the screw head wear cap 1802 is not included and instead a wear element is inserted in the block OUT position covering a screw head contact area (i.e. stopper area) of the jack screw block 1222. In yet another alternative embodiment, the screw head wear cap 1802 is not included and the jack screw block 1222 is formed of a low friction low wear material. A similar example is shown in FIGS. 40-43. This embodiment utilizes a self-retaining wear cap with stepped washer, both of a low friction and low wear material.

FIGS. 20-23 show a portion 2000 of the slide and pivot assembly 806 including the slide torsion plate 808, hinge assembly 810 and a slide-pivot interlock mechanism 2002. The slide-pivot interlock mechanism 2002 is used to hold the slide and pivot assembly in the fully pulled out state. The slide-pivot interlock mechanism 2002 prevents accidental damage to the corresponding process module bias assembly and/or processing chamber by, for example, a user attempting to dock the bias assembly when the corresponding bias mounting plate is not in a fully non-rotated position. The slide-pivot interlock mechanism 2002 also, for example, prevents pivot motion towards the fully non-rotated position unless the slide is in the fully extended pulled out/open position.

The slide-pivot interlock mechanism 2002 includes an attachment bar 2003, a latch bar 2004, a spring (example of a torsion spring is shown in FIGS. 34-35), a stop strip 2008, an adjustable catch bracket 2010, and a toggle stop bracket 2012. The spring may be a torsion spring or a spring of a different type or may be located away from the latch bar center of rotation. When in a fully pulled out state, a bearing roller 2014 on the latch bar 2004 is moved relative to and past the stop strip 2008 and allows the spring to rotate the latch bar 2004 releasing a hooked end 2016 of the latch bar 2004 from the adjustable catch bracket 2010. In an alternate embodiment, the function of the attachment bar 2003 is made an integral part of the torsion plate 808, and the torsion spring function can be achieved using an extension or compression spring.

The torsion spring is disposed between the attachment bar 2003 and the latch bar 2004 and coiled around a torsion pin 2018. The latch bar 2004 includes two slots 2020 corresponding to a pair of pins 2022. The latch bar 2004 rotational limits are defined by movement of the pins 2022 in the slots 2020. An end 2024 of the stop strip 2008 is angled to allow the bearing roller 2014 to roll along the end 2024. The end 2024 may be angled such that the slide and pivot assembly 806 remains in the fully pulled out state and unless a predetermined amount of lateral force is applied on the process module bias assembly to push in the slide and pivot assembly 806 to a fully pushed in state. When the predetermined amount of force is applied, the bearing roller 2014 rotates causing the latch bar 2004 to rotate against the force of the torsion spring and hook the hooked end 2016 on the adjustable catch bracket 2010. A pull cable or other actuation device may be used to pivot the latch bar 2004 into the closing state, or the latch bar may be pivoted into the closing state by pushing on it directly by hand. This would allow a square end, or reverse angle, on the stop strip for a more positive slide lock in the open position.

The adjustable catch bracket 2010 has screws 2030, 2032 to adjust position of the catch bracket 2010 in respective directions relative to the bias mounting plate member 1302. The latch bar 2004 includes a latch bar stop element 2034, which is used to prevent rotation of the latch bar 2004 while the bias mounting plate member 1302 is rotated away from a fully closed (or 90°) state relative to the slide torsion plate member 1300, as shown in FIG. 23. The latch bar stop element 2034 may be implemented as a pin, a flange, a cut-down semi-circular pin or other part, or other stop element. The toggle stop bracket 2012, which is mounted on the slide torsion plate member 1300, contacts the latch bar stop element 2034 and prevents the latch bar 2004 from rotating into the closed position, except when the hinge is in the fully non-rotated position.

The toggle stop bracket 2012 has multiple “L-shaped” portions and is able to slide relative to the slide torsion plate hinge member 1300 along a notch 2040 in a spring holding block 2042, and guide pins in hinge member 1300. The spring holding block 2042 holds a spring 2044 that slides the toggle stop bracket 2012 towards the bias mounting plate member 1302. As the bias mounting plate member 1302 is pivoted open and away from the slide torsion plate member 1300, the toggle stop bracket 2012 slides to the position shown in FIG. 23 to stop rotation of the latch bar 2004. As the bias mounting plate member 1302 is pivoted closed towards the slide torsion plate member 1300, the toggle stop bracket 2012 slides in an opposite direction to no longer be in contact with the latch bar stop element 2034, which allows the hooked end 2016 to engage a hooked end 2050 of the adjustable catch bracket 2010. An alternative embodiment is illustrated in FIGS. 36-39.

FIGS. 24-25 show an example of a bearing assembly 2500 for a hinge assembly, such as the hinge assembly 810 of FIG. 9. Although a particular bearing assembly is shown, other bearing assemblies may be used. Two of the bearing assembly 2500 may be used for both ends of the hinge assembly 810. The hinge assembly 810 includes the members 1300, 1302. The bearing assembly 2500 includes a pin 2502 that extends through holes 2504, 2506 in the members 1300, 1302, a thrust bearing 2508, a tapered roller bearing assembly 2510, a washer 2512 and a lock nut 2514. The roller bearing assembly 2510 includes an outer cup 2516, containing tapered roller hinge pivot bearings 2518 and an inner cone 2520. The roller bearing assembly 1510 sits in a pocket 2530 of the bias mounting plate member 1302.

The tapered roller bearing assembly 2510 improves bias alignment and repeatability, as compared with a simple sleeve bearing assembly. The tapered bearing eliminates clearance between hinge member 1302 and pivot shaft 2502. Bearing clearance contributes to position error during and after the hinge tilt adjustment procedure to compensate for bias mounting plate sag angle (FIG. 26). One of the above disclosed alignment pins (e.g., the pin 2904 of FIG. 28) may be referred to as a clocking alignment pin, which serves to properly align the bias mounting plate angle. When bearing clearance related position error is small and negligible, the clocking pin requirement may be removed. Clocking pin removal eases docking and fastening the bias mounting plate 812 to the processing chamber 802 of FIG. 9.

As an alternative to the bearing assembly of FIGS. 24-25, a sleeve or needle bearing assembly may be used. The alternate bearing assembly may include a fastener, such as a pin, which extends through nuts, thrust bearings, a thrust washer, sleeve bushings and holes in the members 1300, 1302. The sleeve bushings may extend out of the holes and include washer-shaped ends, designated 2060 in FIGS. 20 and 21. As an example, the sleeve bushings may be steel backed and/or polytetrafluorethylene (PTFE) sleeve bushings.

FIG. 26 shows the slide and pivot assembly 806 including the hinge assembly 810 and the bias mounting plate 812. Due to weight of the corresponding process module bias assembly and the slide and pivot assembly 806, sag can occur and is illustrated as an example sag angle. An alignment pin 2710 is shown in an opening 2712 of the bias mounting plate 812. FIG. 30 shows how the hinge assembly 810 is adjusted to account for this sag angle using the hinge adjustment fasteners 1310 of FIG. 13.

FIG. 27 shows an alignment pin 2800 and receiving bushing 2802. The alignment pin 2800 is shown in the chamber wall 1814. The receiving bushing 2802 is shown in the bias mounting plate 812. The alignment pin 2800 has a tapered end 2804 and allows for easy alignment and insertion of the alignment pin 2800 in a hole 2806 of the bushing 2802. The bushing 2802 has a rounded end 2807 for ease in sliding the alignment pin 2800 into the bushing 2802. This aligns the bias mounting plate 812 relative to the processing chamber 802 of FIG. 9, prior to tightening closure fasteners, such as fastener (e.g., bolt or screw) 1216 of FIG. 26. In an embodiment, 4 closure fasteners are used to fasten the bias mounting plate 812 to the processing chamber 802. As an example, the bushing 2802 provides up to 30 microns of pin clearance relative to the bushing 2802. In an embodiment, the alignment pin 2800 is on the bias mounting plate 812 and the bushing 2802 is on the chamber wall 1814.

FIG. 28 shows a portion 2900 of the processing chamber 802 of FIG. 9 including the bias plate with alignment pins 2902, 2904. In FIG. 28, the bias mounting plate member 1302 of the hinge assembly 810 is not shown as being attached to the bias mounting plate 812 and is rotated away from the processing chamber 802. The alignment pin 2904 may be referred to as a clocking alignment pin. In one embodiment, the clocking alignment pin 2904 is not included to ease attachment of the bias mounting plate 812 of FIG. 9 to the processing chamber 802, and to ease the hinge tilt adjustment procedure used to align the bushings and pins.

FIGS. 29 and 30 show a hinge assembly 3000 similar to the hinge assembly 810 of FIG. 9. The hinge assembly 3000 includes the members 1300, 1302 attached to the plates 808, 812. The hinge assembly 3000 includes a tilt adjustment screw 3001, a tilt lock screw 3002, or in an alternate embodiment, eccentric tilt adjustment bushings 3004. The slide torsion plate member 1300 is rotatable about a rotation pin 3006 attached to the slide torsion plate 808. The hinge assembly 810 is shown with different hinge pivot fasteners 3010 than in the previous figures associated with the embodiment of FIG. 9.

The tilt adjustment screw 3001 and/or the tilt lock screw 3002 may be turned to tilt the bias mounting plate CCW to compensate for sag and negate slide plate twist. This may be done while under load. Arrows 3012 represent CCW rotation of the slide torsion plate member 1300 about the pin 3006 and corresponding CCW motion of the hinge assembly 3000 and bias mounting plate 812. Hinge fasteners (e.g., bolts or screws) 3020 are included and tightened down after the tilt adjustment screw 3001 has been adjusted.

FIGS. 31-33 show a portion 3200 of another slide and pivot assembly including a slide torsion plate 3202, a hinge assembly 3204, an attachment bar 3208, and a latch bar 3210. The hinge assembly 3204 includes a slide torsion plate member 3212 and a bias mounting plate member 3214 that is attached to a bias mounting plate.
