Bridges Vs. Interposers


The number of technology options continue to grow for advanced packaging, including new and different ways to incorporate so-called silicon bridges in products. For some time, Intel has offered a silicon bridge technology called Embedded Multi-die Interconnect Bridge (EMIB), which makes use of a tiny piece of silicon with routing layers that connects one chip to another in an IC package. In ... » read more

7nm Design Challenges


Ty Garibay, CTO at ArterisIP, talks about the challenges of moving to 7nm, who’s likely to head there, how long it will take to develop chips at that node, and why it will be so expensive. This also raises questions about whether chips will begin to disaggregate at 7nm and 5nm. https://youtu.be/ZqCAbH678GE » read more

Advanced Packaging Confusion


Advanced packaging is exploding in all directions. There are more chipmakers utilizing different packaging options, more options for the packages themselves, and a confusing array of descriptions and names being used for all of these. Several years ago, there were basically two options on the table, 3D-ICs and 2.5D. But as chipmakers began understanding the difficulty, cost and reduced benef... » read more

Extending The IC Roadmap


An Steegen, executive vice president of semiconductor technology and systems at Imec, sat down with Semiconductor Engineering to discuss IC scaling and chip packaging. Imec is working on next-generation transistors, but it is also developing several new technologies for IC packaging, such as a proprietary silicon bridge, a cooling technology and packaging modules. What follows are excerpts of t... » read more

Analog Migration Equals Redesign


Analog design has never been easy. Engineers can spend their entire careers focused just on phase-locked loops (PLLs), because to get them right the functionality of circuits need to be understood in depth, including how they respond across different process corners and different manufacturing processes. In the finFET era, those challenges have only intensified for analog circuits. Reuse, fo... » read more

Tech Talk: HBM vs. GDDR6


Frank Ferro, senior director of product management at Rambus, talks about memory bottlenecks and why both GDDR6 and high-bandwidth memory are gaining steam and for which markets. https://youtu.be/CPqdZZooS2g » read more

The Case For Chiplets


Discussion about chiplets is growing as the cost of developing chips at 10/7nm and beyond passes well beyond the capabilities of many chipmakers. Estimates for developing 5nm chips (the equivalent 3nm for TSMC and Samsung) are well into the hundreds of millions of dollars just for the NRE costs alone. Masks costs will be in the double-digit millions of dollars even with EUV. And that's assum... » read more

Challenges At The Edge


By Kevin Fogarty and Ed Sperling Edge computing is inching toward the mainstream as the tech industry begins grappling with the fact that far too much data will be generated by sensors to send everything back to the cloud for processing. The initial idea behind the IoT/IIoT, as well as other connected devices, was that simple sensors would relay raw data to the cloud for processing throug... » read more

High-Performance Memory Challenges


Designing memories for high-performance applications is becoming far more complex at 7/5nm. There are more factors to consider, more bottlenecks to contend with, and more tradeoffs required to solve them. One of the biggest challenges is the sheer volume of data that needs to be processed for AI, machine learning or deep learning, or even in classic data center server racks. “The design... » read more

The Race To Mass Customization


The number of advanced packaging options continues to rise. The choices now include different materials for interposers, at least a half-dozen fan-outs, not to mention hybrid fan-out/3D stacking, system-in-package, flip-chip and die-to-die bridges. There are several reasons for all of this activity. First, advanced packaging offers big improvements in performance and power that cannot be ac... » read more
