Description
FIELD

The present disclosure relates to, amongst other things, a semiconductor device package.


BACKGROUND

In modern electronic systems, data typically moves back and forth between the processor and DRAM which is the main memory for most chips. At times, this exchange runs into the memory wall issue resulting from (a) an outdating computing architecture (which has been dominating the semiconductor industry for decades since its inception) with a physical separation between computer processors and memory; and (b) the fact that a processor can run much faster than the speed at which memory chips can provide data. The performance gap created by the memory wall leads to a situation where processors such as CPUs and GPUs spend a significant amount of time waiting and idling for data to be delivered from the memory, thereby significantly impacting system performance, especially for tasks that require large amounts of data to be processed quickly and simultaneously, such as running complex AI algorithms. In fact, the memory wall is quickly becoming a large issue for AI applications since AI accelerators such as today's state-of-the-art Nvidia GPUs (e.g., H100) are specially designed for efficient, high-speed parallel processing of massive amounts of data.


The memory wall issue involves the limited memory capacity and clock speed, and the interconnect bandwidth or bus width of memory transfer. Lack of bandwidth has become a growing limitation for the efficiency and scalability of AI technologies even as DRAM technologies continue to advance towards higher capacities and higher clock speeds. In fact, for AI applications, bandwidth is quickly becoming a limiting factors not only for memory but also at many levels covering the compute level, the network level, and the socket level.


For high-end applications such as high-performance computing (HPC), data centers and artificial intelligence (AI), the industry's solution to address the aforementioned challenges is (a) the expensive high-bandwidth-memory DRAM stack (HBM) which allows for a much higher bandwidth and better efficiency compared to traditional DRAM designs by providing a wider interface at a higher clock speed in combination with (b) 2.5D IC packaging of HBMs and the processor (e.g., the GPU) on a silicon interposer. HBM is more expensive compared to traditional DRAM due to the need for 3D stacking (in the vertical or package thickness direction) that involves a multiplicity of fast DRAM dies (and oftentimes also a control IC), expensive through silicon vias (TSVs) and the fact that HBM contains a multiplicity of dies (DRAM dies and control IC) with a die size that is roughly twice as large as that of traditional DDR5 DRAM. 2.5D IC packaging is also expensive as it involves creating a large number of TSVs in the typically large silicon interposer that accommodates both the processor and the HBMs. In a 2.5D IC package, the HBMs are placed within a few millimeters of the processor to reduce the distances of data transfer and speed up the data transfer process. All the above combined helps alleviate the memory wall issue.


It is the focus of the present invention to disclose alternative, low-cost 3D IC packaging solutions involving stacking dies in the vertical (i.e., package thickness) direction and interconnecting the dies without evoking the expensive TSVs and silicon interposers for more cost—sensitive applications such as edge AI in comparison with the aforementioned high-end applications. As in the case of HBM, stacking memory dies in the vertical direction increases memory capacity using 3D IC packaging. It greatly shortens the distances of and speeds up data transfer between the processor and the memory, and significantly reduces energy consumption. 3D packaging also enables a far higher bus width and interconnect bandwidth due to a far higher number of data paths that can be created between the processor and the memory which is mounted in the vertical direction with the processor (one on top of the other), compared to its 2D or 2.5D counterparts. It is also an intention of the present invention to integrate in lower-cost 3D IC packaging not only the memory dies (and the control IC) but also the processor in close proximity to the memory dies to speed up data transfer between the processor and the memory and to minimize the accompanying energy consumption. When needed, other types of active and passive devices such as interconnect bridges, voltage regulators, inductors and capacitors can also be co-packaged in the disclosed 3D packages. Previous studies have shown that every time data is transferred back and forth across the memory bus, accessing DRAM requires approximately 60 pico-joules for each byte, which is a thousand-fold more energy than processing the data that requires 50-60 femto-joules per computational operation. 3D IC stacking helps speed up data transfer and minimize the required energy consumption due to the short distances data has to travel. It is also worth noting that HBM can provide better pico-joule per bit compared to 2D memory package options for AI accelerators. The 3D IC packages disclosed herein can also be designed (e.g., through IC design and IC package co-design) to maximize this benefit. Even though DRAM is cited herein for demonstration, other types of memory, combinations thereof or other die combinations can also be applied to the structures, processes and methodologies disclosed herein. Moreover, because the 3D IC packages disclosed herein do not require creating TSVs in active dies (which often takes a long time to qualify from IC design), they can be more readily implemented with existing dies in a mix and match fashion for fast time-to-market.

In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawings.


DETAILED DESCRIPTION

The following disclosure provides many different embodiments, or examples, for implementing different features of the provided subject matter. Specific examples of elements and arrangements are described below to simplify the present disclosure. These are, of course, merely examples and are not intended to be limiting. For example, the formation of a first feature over or on a second feature in the description that follows may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be in direct contact. In addition, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.


Further, spatially relative terms, such as “beneath,” “below,” “lower,” “above,” “upper”, “on” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. The spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. The apparatus may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may likewise be interpreted accordingly.


As used herein, the terms such as “first”, “second” and “third” describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer, or section from another. The terms such as “first”, “second”, and “third” when used herein do not imply a sequence or order unless clearly indicated by the context.


This present disclosure was undertaken to enable package-level extensions of known-good-die (KGD) and two-die stack (“doubler”) technologies, while paying attention to devise approaches to expand the doubler technology to covering multiple-die-in-1 DRAM KGDs and multiple-die-in-1 DRAM/processor (logic) combos.


The present disclosure includes the following sections: fast implementation based on flip chip (see FIG. 1, FIG. 2, FIG. 3, FIG. 4 and FIG. 5), doubler extensions (see FIG. 6, FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12A, FIG. 13) and scalable multiple-die-in-1 DRAM KGDs (see FIG. 22, FIG. 24, FIG. 25, FIG. 26, FIG. 27, FIG. 28, FIG. 29, FIG. 30 and FIG. 31). Note that although redistribution layers (RDL) on the DRAM die is optional, it is shown in practically all drawings (and can be omitted as needed to reduce cost) and also that an underfill (or a non-conductive paste or film, NCP) needs to be applied following flip chip bonding though not shown.


Possible structures (and related processes) to implement doublers can be seen in fast implementation (FIG. 6, FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12A, FIG. 13), in doubler extensions involving shifted DRAM dies (when viewed from top in the x-y plane) and in scalable multiple-die-in-1 DRAM KGDs involving aligned DRAM dies (when viewed from top in the x-y plane).


With a few exceptions (e.g., flip chip), wafer-level (/panel-level) fan-out processes are used in creating the structures shown in this disclosure. There exist three primary types of fan-out processes: chip-last/(die) face-down, chip-first/(die) face-up and chip-first/(die) face-down, each of which comes with its pros and cons in route-ability, cost, yield, testability, reliability and time-to-market (that are highly dependent upon application requirements, package design/architecture and OSATs process readiness or capabilities). Fan-out processes create structures with die(s) embedded in a molding compound in a way somewhat similar to the processes to embed die(s) in a laminate substrate, both can come with RDL on one side (top or bottom) or both sides (top and bottom). For complex structures involving more than one RDL for die-to-die interconnection (e.g., doubler structures), chip-last/face-down is favored over the other two types of structures as the former allows for easier decoupling of RDL and assembled chip yields and assurance of known-good RDLs prior to chip assembly for high yields. This, however, does not imply chip-first/(die) face-up and chip-first/(die) face-down are out of the question as they may find sweet spots in certain applications.


Under fast implementation, the doubler structures shown in FIGS. 1 to 3 are based primarily on flip chip, all of which incorporate structural silicon pieces to ensure structural integrity during handling and subsequent processing. In these structures, die-to-die interconnection is achieved using a combination of flip chip, redistribution layers (as needed), copper pillar bumping and fan-out processes. The through-mold vias (TMVs) in FIG. 3, for instance, can be formed using a through-mold via process commonly used in fan-out processing or can be pre-formed in the form of metal pillars (e.g., copper pillars) on the chips.


Besides stacking dies in the vertical or package thickness direction, interconnection between two dies can also be achieved laterally when space is not a constraint as shown in FIGS. 4 and 5 wherein die-to-die interconnection is achieved using a fan-out process and the TMVs can be formed using a through-mold via process commonly used in fan-out processing or can be pre-formed in the form of metal pillars on the chips.


To package doublers beyond those shown (FIGS. 1 to 3) in the category of fast implementation, DRAMs of the same design or different designs can be stacked and packaged differently using different fan-out processes as shown in FIG. 6, FIG. 8, FIG. 9, FIG. 10, FIG. 11, FIG. 12A, and FIG. 13 (all of which fall under doubler extensions) where TMVs can be created by forming metal pillar bumps before molding, and/or a hole opening process (e.g., using an UV laser) commonly used in fan-out processing and metal hole filling after molding. In certain applications, thick film photoresists can also be deposited (e.g., laminated on) in place of the molding compound, in which case photolithography can be employed to open the through mold vias.


When needed, the doubler extension structures can be complemented with attachment of a high-thermal-conductivity (High-TC) heat spreader (and spacers as needed) and a High-TC thermal interface material (TIM) on the backside of the exposed die and spacer as applicable, for example, see 9-1 and 9-8 in FIG. 9.


The doubler extension structures (and processes) can be repeated for the stacking of more than two dies in the thickness direction. A case in point is the stacking of two 4 Gb DRAM dies on a 8 Gb DRAM die as shown in FIG. 12A.


Instead of shifting the position of the top die relative to the bottom die in the lateral direction in forming the shifted 3D stack structure (e.g., see FIG. 6 based on chip-last/face-down under doubler extensions), one can align the two dies laterally in the stack, i.e., the aligned stack structure, as shown in FIG. 22 (under scalable multiple-die-in-1 DRAM KGDs). The latter represents an easier, more scalable structure compared to the shifted 3D structure in terms of achieving stacking dies beyond two dies (see FIG. 25, FIG. 26, FIG. 27, FIG. 28, FIG. 29, FIG. 30 and FIG. 31). To achieve high yields for the structures in FIGS. 6 and 22, the process as shown in FIGS. 7A to 7F can be deployed where the metal pillars can be on known-good redistribution layers 1 (known-good RDL 1 or simply KGR 1) or KGR 2. This process involves building and testing for the two known-good RDLs (KGR 1 and KGR 2 in FIG. 6) separately to ensure only sub-structures involving known-good RDLs are assembled with the two known-good DRAM dies which can come with their own RDLs or without. In forming the 3D structure shown in FIG. 6, a chip-last/face-down fan-out process is assumed. Other types of fan-out processes can also apply here.


The “aligned” structure (and the related processes) in FIG. 22 is scalable with relative ease to stacking of more than two dies as shown in FIG. 25 based on chip-last/face-down), FIG. 26 (based on chip-first/face-up), FIG. 27 (based on chip-first/face-down) and FIG. 28 (based on embedded substrates). For lower-end applications, lower-cost panel-level embedded substrate processes may also be used in place of the wafer-level fan-out processes to achieve die embedding and formation of RDLs.


Following 3D DRAM die stacking, the 3D DRAM stack can be assembled with the processor on the opposite side of the substrates (FIG. 29) or on top of a fan-out embedded processor (or another logic chip such as a controller) as shown in FIG. 30 (without heat spreaders) and in FIG. 31 (with heat spreaders) using the chip-last/face-down multiple-die-in-1 DRAM stack as an example. These package architectures also allow for DRAM dies of different sizes/capacities, other types of dies and active devices, and/or passives (e.g., one capacitor or more and inductors) to be co-packaged in the same fan-out layer of the 3D stack or in the same 3D package.


In summary,

    • to form 2-in-1 DRAM KGDs (whether they be 8 Gb+8 Gb or 4 Gb+8 Gb), it is recommended that one focuses on the structures (and related processes) shown in FIG. 6 (shifted dies) and FIG. 22 (aligned dies) created using chip-last/face-down fan-out processes,
    • for 4 Gb+8 Gb and 8 Gb+8 Gb, the structures shown in FIG. 1 and FIG. 2 created using flip chip also merit some attention,
    • to scale up beyond two dies, it is advisable to use the aligned-die structure as shown in FIGS. 25 to 28.


To create the dual-die structure in FIG. 6, for instance, one can follow the process below:

    • 1. Use a chip-last/face-down fan-out process to create the RDL with copper pillars, 7-75 in FIG. 7A, each of which containing a solder tip, 7-750 to facilitate subsequent joining to KGR 2 on a temporary glass carrier (the first glass carrier), 701, pre-coated with the release (or release/adhesive) layer, 702, followed by using a built-in test circuitry in KGR 1, 7-8, and quality inspection methodologies (e.g., optical inspection) to ensure KGR 1 is known good;
    • 2.
    • Flip chip bond the first DRAM die on the KGR 1 using solder bumps or copper pillar micro-bumps, 7-41 (see FIG. 7B) and an underfill or a NCP, 7-40, and test using the test circuitry in KGR 1 to ensure the known-good KGR 1+DRAM chip sub-assembly (sub-assembly 1);
    • 3. Overmold sub-assembly 1 (see FIG. 7C);
    • 4. Planarize the mold as shown in FIG. 7C to reveal the TMVs and the chip (or alternatively, the TMVs while leaving a layer of molding compound on the backside of the first DRAM);
    • 5. repeat step 1 to create KGR 2 on a second glass carrier and use the test circuitry in the KGR 2 to ensure KGR 2, 7-7 in FIG. 7D, is known good;
    • 6. bond KGR 2 to KGR 1 in sub-assembly 1 and test the newly formed sub-assembly (sub-assembly 2) using the test circuitry in KGR 2 to ensure sub-assembly 2 is known good (alternatively, steps 5 and 6 can be replaced by forming the RDL 2 directly on the planarized mold embodying sub-assembly 1 at the expense of yield loss);
    • 7. flip chip bond the second DRAM die onto the KGR 2—see FIG. 7F;
    • 8. repeat steps 3 and 4 to reveal the second DRAM die and form sub-assembly 3 as shown in FIG. 7F with sub-assembly 3 still being supported by the first temporary glass carrier;
    • 9. (Optional) attach a High-TC heat spreader using a High-TC thermal interface material, TIM, to the backside of the second DRAM die (note: this heat spreader can also serve as a stiffener for enhanced structural integrity during the subsequent assembly process);
    • 10. attach sub-assembly 3 embodying the two dies to a third glass carrier with a release/adhesive layer;
    • 11. release sub-assembly 3 from the first glass carrier and the release/adhesive layer;
    • 12. create appropriate surface finishes (e.g., Ni/Au or Ni/Pd/Au) and bonding pads (and test pads as needed) for subsequent bonding;
    • 13. test through the KGR 1 for known-good final assembly and release it from the third glass carrier;
    • 14. Singulate the final assembly



FIG. 6 shows a 3D shifted-die stack that can be formed using a chip-last/face-down fan-out process as illustrated in FIG. 7A-7F.


A similar structure as shown in FIG. 8 can be created using a chip-first/face-up fan-out process involving the optional use of a spacer (e.g., a silicon spacer), 8-9.


The process to create the dual-die structure in FIG. 22 is similar to that FIGS. 7A to 7F to form the structure in FIG. 6.


Similar methodologies and processes can also be applied to create structures using the chip-first/face-down and chip-first/face-up approaches.


The processes described above can be repeated to create multiple-die-in-1 DRAM KGDs shown in FIG. 12A, FIG. 25, FIG. 26, FIG. 27 and FIG. 28.


Following KGD assembly, the 2-in-1 DRAM KGDs or the multiple-die-in-1 DRAM KGDs can then be interconnected to processors through wire bonding and/or flip chip through the use of a substrate such as a laminate substrate as shown in FIG. 29, FIG. 30 and FIG. 31, wherein the processor can be mounted on the opposite side of the laminate or fan-out substrate to the KGDs, or embedded in the substrate underneath the KGDs (with or without heat spreaders) along with companion active dies (e.g., voltage regulators) and/or passives such as decaps and inductors for power integrity.


The passives (e.g., capacitors and/or inductors) can be embedded in the fan-out layers containing the active dies (e.g., DRAM or other types of active dies), mounted on the substrate and/or embedded in the substrate (see FIG. 29 to FIG. 31).


The laminate substrates can be fine-line/space (L/S) (e.g., 6 μm/8 μm or finer) substrates built using a low-curing-temperature, fine-L/S dielectric such as a polyimide, ABF build-up layers and a BT core and a panel-level laminate substrate process. In contrast, the RDL created by wafer-level fan-out processing can achieve a finer L/S of 2 μm/2 μm and below compared to panel-level substrate processes.


For certain cost sensitive applications, the KGRs can be formed by coreless laminate substrate processes.


The structure shown in FIG. 2 can be created by the following process:

    • 1. Use a chip-first/face-up fan-out process to reconstitute a 12″ glass carrier (pre-coated with a release/adhesive layer) with the first DRAM die, 2-1, and the spacer, 2-8;
    • 2. Apply an encapsulant (e.g., epoxy based filler), 2-65, to fill the spaces between spacers and dies;
    • 3. Flip chip bond the second die, 2-2, to the first die, 2-1;
    • 4. Attach structural silicon pieces, 2-51 and 2-52, which can assume the same or different dimensions with a die attachment material, 2-53 and 2-55;
    • 5. Apply an encapsulant, 2-61, to fill the intervals between structural silicon pieces and the second dies, 2-2;
    • 6. Test to ensure known-good doubler or dual-die assembly; and
    • 7. Release the final assembly from the glass carrier and singulate it.


Interim and final testing can be perform to ensure known-good sub-assemblies and final assembly, respectively.


An alternative to the structure shown in FIG. 2 is depicted in FIG. 3 which uses a chip-first/face-up fan-out process to create the die 1 and spacer combo sub-assembly with the die 1 RDL, 3-5, and micro-TMVs which interconnect the die 1 pads and the die 1 RDL, followed by steps 3 to 5 of the process above to form the structure in FIG. 2.
