The Best Foundry Strategy


By Joanne Itow Today, foundries supply more than 20% of the silicon used to produce all the semiconductor products sold. The foundry impact has grown from only 10% in 1997 to 24% today. The significance of foundries is even more evident when focused on logic wafers alone. Figure 1. Foundry Wafers as a Percent of Total, IC’s, and IC’s Minus Memory [caption id="attachment_7339" align="... » read more

Making The Right Choices


FD-SOI at 28nm, or finFETs at 20/14nm? To companies looking at the cost equation, the total market opportunity for SoCs and the NRE required to get there, this is still a manageable formula. It requires lots of number crunching and some unknowns, but by the time you get done with the math it still falls within an acceptable margin of error and the choices are relatively simple. For foundries... » read more

SOI Highlights at Common Platform Tech Forum


Posted by Adele Hars, Editor-in-Chief, Advanced Substrate News ~  ~ The 2013 Common Platform Technology Forum showcased “the latest technological advances being delivered to the world’s leading electronics companies,” so of course SOI-based topics were well-represented. Happily, those of us who weren’t able to get over to Silicon Valley were able to attend “virtually” via a ... » read more

New Issues In Signoff


By Ed Sperling Signoff has always been a challenge at every stage of an SoC design flow. No matter how good a design looks, or how well a prototype works, there are still problems that can crop up at any stage of the design flow all the way into manufacturing that can leave engineering teams shaking their heads. Even at mainstream process nodes, respins are common. At advanced nodes—part... » read more

Uncommon Goals


I had the opportunity to attend the Common Platform event recently. This is a technology and business showcase sponsored by Global Foundries, IBM and Samsung with major support from ARM, Cadence, Synopsys and Mentor. Wow, that’s some serious sponsorship. The event was well run and provided a good balance of technology details and business outlook. The wine at the evening reception was decent ... » read more

Tech Talk: Getting To The Next Node


IBM's Gary Patton talks with Low-Power/High-Performance Engineering about finFETs, EUV, and the challenges of staying on the Moore's Law road map. [youtube vid=jtz9XSXyBp0] » read more

Math Questions


The race is on. GlobalFoundries, TSMC, Samsung, IBM and Intel are all neck deep in research, test chips, variability, lithography and three-dimensional transistor designs. For the first time, though, the goal very publicly has shifted from performance and area to energy efficiency. Being able to double battery life with existing performance over the next couple nodes could mean smart phones ... » read more

What Will Replace Dual Damascene?


By Mark LaPedus In the mid-1990s, IBM announced the world’s first devices using a copper dual damascene process. At the time, the dual damascene manufacturing process was hailed as a major breakthrough. The new copper process enabled IC makers to scale the tiny interconnects in a device, as the previous material, aluminum, faced some major limitations. Dual damascene remains the workhorse... » read more

Lessons From Past Architecture Wars


By Marc David Levenson There was an interesting IEEE panel discussion in Silicon Valley recently, reviewing the microprocessor architecture wars of the ’70s, ’80s and ’90s. How did the Intel x86 architecture become so dominant when there were other capable designs, including more efficient RISC (Reduced Instruction Set Computing) chips? How did the x86s overcome competition from Zilog, M... » read more

Tradeoffs On The Fly


By Ann Steffora Mutschler With classical bulk planar technology no longer shrinkable, the industry has been honing in on new ways to continue some scaling, achieve extra speed or better power while minimizing leakage. “To overcome the limits [of bulk planar technology] we need a different solution,” explained Giorgio Cesano, technology R&D marketing director at STMicroelectron... » read more
