Reflections On 2015


It is easy to make predictions, but few people can make them with any degree of accuracy. Most of the time, those predictions are forgotten by the end of the year and there is no one to do a tally of who holds more credibility for next year. Not so with Semiconductor Engineering. We like to hold people's feet to the fire, but while the "Pants-On-Fire" meter may be applicable to politicians, we ... » read more

What China Is Planning


Over the years, China has unveiled several initiatives to advance its domestic semiconductor industry. China has made some progress at each turn, although every plan has fallen short of expectations. But now, the nation is embarking on several new and bold initiatives that could alter the IC landscape. China’s new initiatives address at least three key challenges for its IC industry: 1. C... » read more

Abstraction: Necessary But Evil


Abstraction allows aspects of a design to be described in an executable form much earlier in the flow. But some abstractions are breaking down, and an increasing amount of lower-level information has to be brought upstream in order to provide estimates that are close enough to reality so informed decisions can be made. The value of abstractions in design cannot be overstated. High levels of ... » read more

Pick A Number


For the past two years there was some mumbling that 16/14nm would be short-lived, and that 10nm would be the place that foundries would invest heavily. Now the buzz is that 10nm may be skipped entirely and the next node will be 7nm. After all, 10nm is really only a half-node. Or is it? The answer depends on who's defining 10nm. The 16/14nm node is based on a 20nm back-end-of-line process, un... » read more

A Strategy For Designing For Power With FinFETs


Recently Qualcomm announced their new SnapDragon processor 820, which was designed using finFET technology. They showed some amazing results, such as 2X improvement in performance and 2X improvement in power compared to 28nm designs. Previously, when ARM announced their A72 processors in finFET, they too had claimed 3.5X improvement in power compared to 28nm designs. But can designers expect... » read more

Interconnect Challenges Grow


It’s becoming apparent that traditional chip scaling is slowing down. The 16nm/14nm logic node took longer than expected to unfold. And the 10nm node and beyond could suffer the same fate. So what’s the main cause? It’s hard to pinpoint the problem, although many blame the issues on lithography. But what could eventually hold up the scaling train, and undo Moore’s Law, is arguably t... » read more

Tech Talk: 10nm Patterning


David Abercrombie, advanced physical verification methodology program manager at Mentor Graphics, talks about triple and quadruple patterning after 20/16/14nm and what design teams need to understand to get this right. [youtube vid=7bjutPWakpw] » read more

Moving Electrons Is Getting Harder


Numerous executives across the ecosystem—from EDA and equipment companies to foundries—recently have stated that Moore's Law has at least 10 more years of life. This is interesting math, considering the semiconductor industry is now working on 10nm, with chips expected to roll out next year. So given that Moore's Law is on a two-year cadence of doubling the number of transistors every 24... » read more

Which Process, Material, IP?


For years chipmakers have been demanding more choices. They've finally gotten what they wished for—so many possibilities, in fact, that engineering teams of all types are having trouble wading through them. And to make matters worse, some choices now come with unexpected and often unwanted caveats. At the most advanced nodes it's a given that being able to shrink features and double patter... » read more

Tech Talk: Wafer Plane Analysis


Leo Pang, executive vice president at D2S, talks about the problems of patterning at 40nm and below and how to deal with them more effectively using existing equipment. [youtube vid=FbRyhw2q3fE] » read more
