So if you think about CMP, there are particles in the slurries. DRAM fabrication will need to evolve to meet the demands of high-performance devices over the next few years. controller die in the package. Adesto Technology produced its second generation CBRAM, and is working on its third-generation solutions. Packaging appears to be further along from a technology standpoint than from a supply chain standpoint. they use their own unique vertical channel capping structures. 2080. Gate pitch went from 66 to 57, and metals from 44 to 40. applying their XPoint memory devices into NAND and storage products such as Zhang: Our customers are marching down the path of 1x, 1y, 1z, and trying to squeeze out another nanometer. Unlike NAND, where cost-per-unit-cell drives innovation, fast switching speed must be prioritized. TechInsights cell design scaling down process is slowing due to many scaling issues With more and more stacking and multiple patterning, you have more CMP, and then you have to get this gunk out. As a result, the expected lifetime of the electronics systems is well beyond the lifetime of the vehicle itself. They were able to go from 8.25 tracks to 6 tracks. But the pillars are getting skinny and tall, which is creating a new challenge because the cameras are at a fixed angle.

The company has also established a development team for 16nm DRAM (Kevlar) project, which will enter mass-production in 2020 at the earliest. At the same time, if we wait on 5nm, we miss that window. High-density fan-out on wafer-level or panel-level is another. But all of those have important implications for design, reliability and test. Intel introduces Iris Xe MAX discrete GPU (mobile) graphics “That technology ran into issues with scaling. “They’ve gone 19 to 18 to 17 to 15 to 14, which is the 1x, 1y, 1z, 1a, 1b node. Both use double stacked 96L (two-step VCH etching). DRAM architecture has remained virtually unchanged for the past decade, with the dimensions shrinking proportionally with each successive device node. Experts at the Table: Extensible instruction-set architecture is drawing attention from across the industry and supply chain. i5-8305G HBM2 products use Samsung’s 2y nm HBM2 dies. Source: Intel, “Chiplets are at an inflection point,” said Calvin Cheung, vice president of engineering at ASE. Cleaning chemistries must be tailored to the CMP process for adequate residue removal. Intel’s next-gen MRAM; silicon oxide ReRAM; FeFETs. But it could not be adopted in mobile because of the high price. This is selective modification. As the benefits of Moore’s Law scaling erode at each new node after 16/14nm, different approaches are required to achieve power, performance and area/cost improvements. And because of the gap between the pitch on the substrate and the pin side, there are several packaging technologies that have been developed to bridge that gap. New types of stacking also require different technologies, not all of which are ready today. The standards to measure reliability under the tough conditions a car presents are based on how vehicles operate today. Designing, integrating and assembling heterogeneous packages from blocks developed at any process node or cost point is proving to be far more difficult than expected, particularly where high performance is one of the main criteria. That means you need to do 100% of the inspection in 3D for things like ball height planarity. The automotive supply chain is transforming with the development of autonomous vehicles. They also involve the materials used to create chips. 8. This already is happening in the memory world. Improvements in density have largely been dealt with one node at a time, although not necessarily in a straight line. Intel has created an entire architecture called Foveros based upon chiplets, connected physically through its Embedded Multi-die Interconnect Bridge (EMIB) as well as an on-chip network, which it acquired when it bought NetSpeed Systems last year. Related Stories The answer can be different, depending on how you are partitioning an FPGA, CPU or GPU. Samsung will probably use Extreme Ultraviolet (EUV) exposure equipment for the 16nm DRAMs. At some point, incremental improvements are no longer sufficient, and further device shrinking requires a completely different technology. cell (PUC) structure, or 4D NAND, is quite different from their previous But even if industry-wide standards do become prevalent, ensuring reliability with chips in a packaging is much more time-consuming than with a planar chip. Toshiba/Western Digital 96L and Intel/Micron DRAM, which consists of a transistor and a capacitor, Figure 2, is a volatile memory, meaning that data is lost when power is shut off to the cell. This linear path, however, is reaching its limits for nodes below 20 nanometers (nm) including 1x, 1y, 1z, 1a, and 1b. DRAM cell scaling down to a 17nm design rule has already been productized by major DRAM players including Samsung, Micron and SK Hynix (Figure 1). Materials issues It’s not always clear where you point your resources. Name*(Note: This name will be displayed publicly), Email*(This will not be displayed publicly). That isn’t for lack of trying. The quest to develop these devices is driving integrated device manufacturers (IDMs) to push semiconductor manufacturing technology to its very limits. A similar, less-costly approach involves the use of a bridge interconnect between die. DRAM architecture has remained virtually unchanged for the past decade, with the dimensions shrinking proportionally with each successive device node. A major change will be needed soon if DRAM is to keep up with advances in logic. In the past, it was all about performance. including patterning, leakage and sensing margin. entegris.com/storage-class-memory-advances-in-materials-new-device-architecture-for-high-density-phase-memory-wp. In some cases they have had to move to slightly new processes to get the new process window they need, from CVD to ALD, for example.”, DRAM, likewise, used to follow the traditional logic nodes until manufacturing moved into the 1x node. “One of the questions we get asked a lot is what is the right packaging platform for heterogeneous integration,” said Suresh Ramalingam, a Xilinx fellow in charge of the company’s advanced packaging. But adding layers is not scaling. The maximum allowed size of killer and latent defects reduces with each advancing node. We need to be able to create more good information at the same cost.”. “It’s typically a mix of many products from many customers. What gets etched into each cylindrical portion of that honeycomb pattern gets smaller at each new node, and there is less high-k material to store a charge. This, in turn, charges the storage capacitor, where every data bit is stored. However, the emphasis on reliability is very clear, and it is spreading into a variety of markets, such as smartphones. “We are taking necessary procedures to mass-produce 1a EUV DRAMs early 2021.” The company is also drawing a roadmap that will have the development of 1b EUV DRAM completed in 2022. Intel and Micron again stacked two NAND strings such as This is why scaling has slowed on DRAM, and why HBM is becoming a better choice for high-performance applications. But we’re also broadening this out to improve reliability. If you look at their fin and metal pitches, they weren’t that aggressively scaled. If you want to source the silicon interposer by itself, it is very difficult. A lot of experimentation is happening with advanced packaging. The fin pitch is only slightly reduced, but they were able to significantly reduce total track height via fin depopulation.”. You reduce the die size and also the power.

Lam’s CTO talks about how more data, technology advances and new materials and manufacturing techniques will extend scaling in multiple directions. As We talk about power delivery for chiplets. Gb die. This is largely a chicken-and-egg problem. products. If you’re able to reduce that variation in the gate cut edge placement, then you can have tighter design rules and get incremental improvements in area scaling. smartphones used 2D NAND; since 2017, both 2D and 3D NAND devices have been the area and cost/throughput. “Do we move to 5nm right away or do we optimize on 7nm, or do we go in a different direction and develop additional IP at older nodes. Depending on the type of package, alignment can become problematic because the chips can move during the packaging process. method as 64L products. DRAM, likewise, used to follow the traditional logic nodes until manufacturing moved into the 1x node. Conclusion Dr. Choe’s background 512 Gb 3D NAND dies are common. Variation can be controlled much more tightly than in the past, and that should improve predictability and yield and ease some of the restrictions on designs. And that will be the differentiator. “Variation mainly speaks to the design rule offsets,” Lenox said. This linear path, however, is reaching its limits for nodes below 20 nanometers (nm) including 1x, 1y, 1z, 1a, and 1b. Why multi-die solutions are getting so much attention these days. After that, they didn’t go 18 to 14 to 7 to 5nm. Gb GDDR6 packages with 8 Gb GDRAM dies for the NVIDIA GeForce RTXTM "After 1x (18nm), 1y (17nm), and 1z (16nm), the process nodes will be reduced to 1a, 1b, 1c, and 1d." Variation Issues Grow Wider And Deeper But some of the challenges involve the packaging complexity. After that, they didn’t go 18 to 14 to 7 to 5nm. ODI is bump-to-bump and it is the shortest channel.”. There is an embedded layer in the substrate. Using Sensor Data To Improve Yield And Uptime That has made 2.5D more popular, where different dies are connected to an interposer layer packed with TSVs. “In the past, most of our materials have been sacrificial,” said Srikanth Kommu, executive director of the semiconductor business at Brewer Science. DRAM Mask Counts • DRAM mask counts by node and company. This linear path, however, is reaching its limits for nodes below 20 nanometers (nm) including 1x, 1y, 1z, 1a, and 1b. with B-RCAT and cylindrical capacitor. But processes and flows still need to mature before cost and development time can be reduced sufficiently for many applications. Big Shifts In Big Data Several groups are attempting to hammer out common specs for interconnects, among other things, including IEEE, DARPA and at least one group of companies.
