Chiplets Still A Challenge With UCIe 2.0


Plug-and-play chiplets are a popular goal, but does UCIe 2.0 move us any closer to that becoming a reality? The problem is that the current drivers of the standard are not after interoperability in the way that plug-and-play requires. Released in August 2024, UCIe 2.0 touts higher bandwidth density and improved power efficiency, as well as new features supporting 3D packaging, a manageable s... » read more

Global IC Fabs And Facilities Report: 2024


The chip industry made significant capital investments this year to build new fabs and facilities or expand existing premises. A number of sites were dedicated to SiC, GaN, DRAM, HBM, along with packaging and assembly by OSATs, and essential gases, chemicals, and other components. More than a dozen R&D centers were also established for 8-inch wafers, EUV, and advanced packaging. Investments... » read more

What’s The Best Way To Sell An Inference Engine?


The burgeoning AI market has seen innumerable startups funded on the strength of their ideas about building faster, lower-power, and/or lower-cost AI inference engines. Part of the go-to-market dynamic has involved deciding whether to offer a chip or IP — with some newcomers pivoting between chip and IP implementations of their ideas. The fact that some companies choose to sell chips while... » read more

What’s Next For Through-Silicon Vias


From large TSVs for MEMS to nanoTSVs for backside power delivery, cost-effective process flows for these interconnects are essential for making 2.5D and 3D packages more feasible. Through-silicon vias (TSVs) enable shorter interconnect lengths, which reduces chip power consumption and latency to carry signals faster from one device to another or within a device. Advanced packaging technology... » read more

Navigating Increased Complexity In Advanced Packaging


As chips evolve toward stacked, heterogeneous assemblies and adopt more complex materials, engineers are grappling with new and often less predictable sources of variation. This is redefining what it means to achieve precision, forcing companies to rethink everything from process control and in-line metrology to materials selection and multi-level testing. These assemblies are the result of ... » read more

Auto Chip Aging Accelerates In Hot Climates


Automotive chips are aging significantly faster than expected in hot climates with sustained high temperatures, raising concerns about the reliability of electrified vehicles over time and whether advanced-node chips are the right choice for safety-critical applications. Many of the most advanced electronics used in vehicles today are ASIL D-compliant, expected to function up to 125° C. But... » read more

NAND Flash Targets 1,000 Layers


The chip industry is pushing to quadruple the stack height of 3D NAND flash from 200 layers to 800 layers or more over the next few years, using the additional capacity will help to feed the unending need for more memory of all types. Those additional layers will add new reliability issues a number of incremental reliability challenges, but the NAND flash industry has been steadily increasin... » read more

Top-Down Vs. Bottom-Up Chiplet Design


Chiplets are gaining widespread attention across the semiconductor industry, but for this approach to really take off commercially it will require more standards, better modeling technologies and methodologies, and a hefty amount of investment and experimentation. The case for chiplets is well understood. They can speed up time to market with consistent results, at whatever process node work... » read more

HBM Options Increase As AI Demand Soars


High-bandwidth memory (HBM) sales are spiking as the amount of data that needs to be processed quickly by state-of-the-art AI accelerators, graphic processing units, and high-performance computing applications continues to explode. HBM inventories are sold out, driven by massive efforts and investments in developing and improving large language models such as ChatGPT. HBM is the memory of ch... » read more

Shift Left Is The Tip Of The Iceberg


Shift left is evolving from a buzzword into a much broader shift in design methodology and EDA tooling, and while it's still early innings there is widespread agreement that it will be transformative. The semiconductor industry has gone through many changes over the past few decades. Some are obvious, but others happen because of a convergence of multiple factors that require systemic change... » read more
