Large-Scale Integration’s Future Depends On Modeling


VLSI is a term that conjures up images of a college textbook, but some of the concepts included in very large-scale integration remain relevant and continue to evolve, while others have fallen by the wayside. The portion of VLSI that remains most relevant for semiconductor industry is "integration," which is pushing well beyond the edges of a monolithic planar chip. But that expansion also i... » read more

High-NA Lithography Starting To Take Shape


The future of semiconductor technology is often viewed through the lenses of photolithography equipment, which continues to offer better resolution for future process nodes despite an almost perpetual barrage of highly challenging technological issues. For years, lithography was viewed as the primary manufacturing-related gating factor to continued device scaling, beset by multiple delays th... » read more

Using ML For Improved Fab Scheduling


Expanding fab capacity is slow and expensive even under ideal circumstances. It has been still more difficult in recent years, as pandemic-related shortages have strained equipment supply chains. When integrated circuit demand rises faster than expansions can fill the gap, fabs try to find “hidden” capacity through improved operations. They hope that more efficient workflows will allow e... » read more

Goals of Going Green


The chip industry is stepping up efforts to be seen as environmentally friendly, driven by growing pressure from customers and government regulations. Some manufacturers have been addressing sustainability challenges for more than a decade, but they are becoming more aggressive in their efforts, while others are joining them. A review of sustainability reports across the semiconductor indust... » read more

Improving Performance And Lowering Power In Automotive


Automotive OEMs are boosting their investments across the semiconductor ecosystem as stepping stones toward electrification and autonomy, and they are starting to encounter some of the same issues chipmakers have been wrestling with at advanced nodes — massive compute performance, thermal and power issues, reliability over extended lifetimes, and a highly diverse and geographically distribute... » read more

Getting Rid Of Heat In Chips


Power consumed by semiconductors creates heat, which must be removed from the device, but how to do this efficiently is a growing challenge. Heat is the waste product of semiconductors. It is produced when power is dissipated in devices and along wires. Power is consumed when devices switch, meaning that it is dependent upon activity, and that power is constantly being wasted by imperfect de... » read more

HBM’s Future: Necessary But Expensive


High-bandwidth memory (HBM) is becoming the memory of choice for hyperscalers, but there are still questions about its ultimate fate in the mainstream marketplace. While it’s well-established in data centers, with usage growing due to the demands of AI/ML, wider adoption is inhibited by drawbacks inherent in its basic design. On the one hand, HBM offers a compact 2.5D form factor that enables... » read more

Demand For Timing Innovation Grows


The semiconductor industry has begun exploring a range of timing options as demand for increased performance and more features exceeds the ability to design chips using the same techniques and technology that have been relied on for decades. Like many elements in computing, timing is a hierarchy or stack. It includes everything from partitioning AI computations into multiple parts and assemb... » read more

Wi-Fi 7 Moves Forward, Adding Yet Another Protocol


The latest generation Wi-Fi protocol brings better speeds and data handling, but it does little to bridge various communications technologies. That, in turn, makes it more difficult and more expensive to design chips because they must integrate and support multiple wireless technologies, including different versions of the same technology. Wireless communications technologies are often victi... » read more

Mission-Critical Devices Drive System-Level Test Expansion


System-level testing is becoming essential for testing complex and increasingly heterogeneous chips, driven by rising demand for reliable parts in safety- and mission-critical applications. More and more chip manufacturers are jumping on the SLT bandwagon for high-volume manufacturing (HVM) of these devices. Unlike ATE and packaged device testing, SLT mimics actual semiconductor system opera... » read more
