Need For Speed Drives Targeted Testing


As packaging complexity increases and nodes shrink, defect detection becomes significantly more difficult. Engineers must contend with subtle variations introduced during fabrication and assembly without sacrificing throughput. New material stacks degrade signal-to-noise ratios, which makes metrology more difficult. At the same time, inspection systems face a more nuanced challenge — how t... » read more

HW-based Heterogeneous Memory Management for LLM Inferencing (KAIST, Stanford Unversity)


A new technical paper titled "Hardware-based Heterogeneous Memory Management for Large Language Model Inference" was published by researchers at KAIST and Stanford University. Abstract "A large language model (LLM) is one of the most important emerging machine learning applications nowadays. However, due to its huge model size and runtime increase of the memory footprint, LLM inferences suf... » read more

Co-Design Optimization For PI/SI When Considering Thermal Performance


When applications become more complex, higher data rates or high frequencies are required. However, with increasing functions, more power dissipation will be generated. Furthermore, temperature is proportional to power dissipation, so electrical performance will also depend on thermal conditions. To determine how temperature impacts power integrity/signal integrity (PI/SI), electrical simulatio... » read more

Chip Industry Week In Review


[Podcast version is here.] TSMC said it will produce 30% of its leading-edge chips in Arizona when all six of its fabs are operational, a total investment of $165 billion, Axios reported. In its latest SEC filing, the foundry said it continues to add capacity in Taiwan, Arizona, Japan, and Germany. The Trump administration launched a Section 232 investigation into semiconductors and relat... » read more

The Other Side Of The Wafer: Transistor Channel Stress In Backside Power Delivery Networks


As transistor scaling has moved to the angstrom era (18A, 14A, etc.), the issues of interconnect resistance (IR), IR drop, and power loss are becoming more severe. Traditionally, signal lines and power lines are fabricated on the same side of the wafer as the active device. But fabricating everything on one side of the wafer can create a shortage of space and resources at the interconnect la... » read more

TCAD For GPUs And GPUs For TCAD


It is well known that many steps in chip development become exponentially harder as feature sizes shrink and instance counts balloon. Billions of transistors are now commonplace, and wafer-scale devices with trillions are on the horizon. Such massive chips put pressure on every electronic design automation (EDA) tool in the development flow, from front-end architectural modeling to signoff and ... » read more

Can Chiplets Serve Cost-Conscious Apps?


Chiplets are emerging as a significant new phase in the evolution of the semiconductor market, providing a way to continue scaling performance well beyond the size limitations of a reticle. But that improvement comes with a high price tag and a lot more complexity, which so far has limited adoption. One of the main reasons for the cost increase is the need for advanced packaging when employi... » read more
