"In this paper, we present an system-technology co-optimization (STCO) framework that interfaces with workload-driven system scaling challenges and physical design-enab... » read more

DTCO/STCO Create Path For Faster Yield Ramps


Higher density in planar SoCs and advanced packages, coupled with more complex interactions and dependencies between various components, are permitting systematic defects to escape traditional detection methods. These issues increasingly are not detected until the chips reach high-volume manufacturing, slowing the yield ramp and bumping up costs. To combat these problems, IDMs and systems co... » read more

Everyone’s A System Designer With Heterogeneous Integration


The move away from monolithic SoCs to heterogeneous chips and chiplets in a package is accelerating, setting in motion a broad shift in methodologies, collaborations, and design goals that are felt by engineers at every step of the flow, from design through manufacturing. Nearly every engineer is now working or touching some technology, process, or methodology that is new. And they are inter... » read more

Chiplets: Bridging The Gap Between The System Requirements And Design Aggregation, Planning, And Optimization


A technical paper titled “System and Design Technology Co-optimization of Chiplet-based AI Accelerator with Machine Learning” was published by researchers at Auburn University. Abstract: "With the availability of advanced packaging technology and its attractive features, the chiplet-based architecture has gained traction among chip designers. The large design space and the lack of sys... » read more

The Path To Known Good Interconnects


Chiplets and heterogenous integration (HI) provide a compelling way to continue delivering improvements in performance, power, area, and cost (PPAC) as Moore’s Law slows, but choosing the best way to connect these devices so they behave in consistent and predictable ways is becoming a challenge as the number of options continues to grow. More possibilities also bring more potential interac... » read more

IEDM Keynote: Ann Kelleher On Future Technology


IEDM 2022 celebrated 75 Years of the Transistor. I can't imagine anything else invented in the last 75 years has had as much effect on my life, and probably yours, too. After the awards session, the conference got underway with a keynote by Ann Kelleher, Executive Vice President and General Manager of Technology Development at Intel. It was titled "Celebrating 75 Years of the Transistor! A L... » read more

What’s Next For Transistors And Chiplets


Sri Samavedam, senior vice president of CMOS Technologies at Imec, sat down with Semiconductor Engineering to talk about finFET scaling, gate-all-around transistors, interconnects, packaging, chiplets and 3D SoCs. What follows are excerpts of that discussion. SE: The semiconductor technology roadmap is moving in several different directions. We have traditional logic scaling, but packaging i... » read more

Shifting Left: Early Multi Physics Analysis For STCO


With the economics of transistor scaling no longer universally applicable, the industry is turning to innovative packaging technologies to support system scaling demands and achieve lower system cost. This has led to the emergence of a system technology co-optimization (STCO) approach, in which an SoC is disaggregated into smaller modules (also known as chiplets) that can be asynchronously desi... » read more

Using A System Technology Co-Optimization (STCO) Approach For 2.5/3D Heterogeneous Semiconductor Integration


With the economics of transistor scaling no longer universally applicable, the industry is turning to innovative packaging technologies to support system scaling demands and achieve lower system cost. This has led to the system technology co-optimization (STCO) concept, where a SoC type system is disaggregated, or partitioned, into smaller modules (also known as chiplets) that can be asynchrono... » read more
