3D-IC Ecosystem Starts To Take Form


The adoption of chiplets is inevitable, but exactly when a mass migration toward this design approach will begin is yet to be determined. Nevertheless, some of the biggest technological and business-related barriers are being addressed. And while a chiplet-based design remains beyond the economic reach of many companies today, that is starting to change. Early signs of an emerging ecosystem ... » read more

Nearly Invisible: Defect Detection Below 5nm


Detecting sub-5nm defects creates huge challenges for chipmakers, challenges that have a direct impact on yield, reliability, and profitability. In addition to being smaller and harder to detect, defects are often hidden beneath intricate device structures and packaging schemes. Moreover, traditional optical and electrical probing methods, trusted for decades, are proving inadequate against ... » read more

Bold Prediction: 50% Of New HPC Chip Designs Will Be Multi-Die In 2025


Monolithic chips have been the workhorses behind decades of technological advancement. But just as the industrial revolution saw workhorses replaced with more efficient and powerful machinery, the semiconductor industry is on the cusp of a similar revolution. Multi-die and chiplet-based designs — which integrate multiple specialized dies in a single package or stack integrated circuits ver... » read more

Chip Architectures Becoming Much More Complex With Chiplets


The migration from monolithic SoCs to chiplet-based designs is creating a confusing array of options and tradeoffs for design teams working at the leading edge, and the number of choices is only going to increase as third-party chiplets begin pouring into the market. That hasn't dampened the appetite for chiplets, however, which are deemed essential for future generations of semiconductors f... » read more

Assembly Design Rules Slowly Emerge


Process design kits (PDKs) play an essential in ensuring that silicon technology can proceed from one generation to the next in a manner that design tools can keep up with. No such infrastructure has been needed for packaging in the past, but that's beginning to change with advanced packages. Heterogeneous assemblies are still ramping up, but their benefits are attracting new designs. “Chi... » read more

Startup Challenges In A Changing EDA World


The Electronic Design Automation (EDA) industry is a mature industry, but it's also one that is constantly changing. Each process node and packaging technology advancement places new demands and constraints on existing tools. In addition, changing design problems and paradigms transform how design teams operate, and the goals they target. For a relatively small industry, EDA requires a dispr... » read more

Testing For Thermal Issues Becomes More Difficult


Increasingly complex and heterogeneous architectures, coupled with the adoption of high-performance materials, are making it much more difficult to identify and test for thermal issues in advanced packages. For a single SoC, compressing higher functionality into a smaller area concentrates the processing and makes thermal effects more predictable. But that processing can happen anywhere in a... » read more

Metrology Advances Step Up To Sub-2nm Device Node Needs


Metrology and inspection are dealing with a slew of issues tied to 3D measurements, buried defects, and higher sensitivity as device features continue to shrink to 2nm and below. This is made even more challenging due to increasing pressure to ramp new processes more quickly. Metrology tool suppliers must exceed current needs by a process node or two to ensure solutions are ready to meet tig... » read more

Ensure Reliability In Automotive ICs By Reducing Thermal Effects


In the relentless pursuit of performance and miniaturization, the semiconductor industry has increasingly turned to 3D integrated circuits (3D-ICs) as a cutting-edge solution. Stacking dies in a 3D assembly offers numerous benefits, including enhanced performance, reduced power consumption, and more efficient use of space. However, this advanced technology also introduces significant thermal di... » read more
