Looking Beyond Moore’s Law


For decades, chip scaling has followed a simple linear curve. In this curve, the transistor gate-pitch scales at 0.7x every two years. This is the driving force behind Moore’s Law, which states that the number of transistors per chip roughly doubles every two years. But starting at the 16nm/14nm node, there is a change taking place in chip scaling. According to a chart from Imec, there are... » read more

IMEC’s 30th Anniversary: A Consortium With Impact


In the history of semiconductor technology, one of the critical non-technology changes was the point when the biggest companies realized that they could not afford to do all the basic R&D. They agreed to collaborate in “pre-competitive” phase development through consortia such as IMEC and Sematech. IMEC is celebrating its 30th anniversary, and it’s interesting to recognize the signifi... » read more

Printed Electronics Gets Serious About Manufacturing


A leading indicator in the coming-of-age saga of a new technology is the enthusiasm to be in the business of supplying manufacturing infrastructure. To sell infrastructure, there needs to be a belief that there are several customers out there. At the recent IDTech conference for printed electronics, the transition to manufacturing was clear based on those who presented and some notable absences... » read more

The Trouble With Triples—Part 2


In my last blog, we started to look at some of the challenges of triple patterning (TP) compared to double patterning (DP). In particular, we looked at the algorithmic complexity of determining if a valid coloring solution exists, and if so, producing a three-mask decomposition. This time, let’s look into the challenges of what to do if a layout is not legally decomposable into three colors. ... » read more

Beyond The CES Hype


Now that the dust has settled, it’s time to realistically assess all the activity at CES 2014. The big screen TVs, the shiny new cars and all the excitement over Internet of Things certainly dazzled the CES show floor. But how much of it is hype and what will really become sustainable products? Smart lighting, smart refrigerators, smart cars, and a smart thermostat are all part of what is... » read more

Fab Tool Industry Has Lost Its Way


The relationship between chipmakers and fab tool vendors has always been a bit rocky, but the supply chain has generally worked. Chipmakers demand a tool for a particular application. Then, tool makers attempt to deliver the goods, and ask few, if any, questions. Now, fab tool executives are beginning to ask some tough questions about the industry. And the tension is mounting between equ... » read more

Routing Closure Challenges At 28nm And Below


As I described in my last article, the gap between router tech files and signoff rule decks at 28 nm and below is generating some serious impacts on tapeout schedules. The mismatch between the router’s simplified tech file and the complex rules that represent the intricate manufacturing requirements at these leading-edge nodes means designs that come from the router “DRC/DFM-clean” will, ... » read more

Different Economies Of Scale, And Lots Of Questions


Being able to shrink features and reach the next node is already an exclusive club. It will become more exclusive at 16/14nm, which is expected to hit volume production in 2015, and even more exclusive still at 10nm. In fact, it may begin to look like a semi-private affair. The argument being presented is that economies of scale will still exist for those companies with pockets deep enough ... » read more

2014 CapEx: Memory Is Leading The Way


The semiconductor industry is expensive. Billions of dollars are spent every year to keep the fabs running, build new fabs, and push the process technology to greater and greater heights. Billions more will be spent to make 450mm production a reality. In January 2013, Semico predicted that, based on initial indications from some companies, total CapEx would be flat this year. Based on current d... » read more

What Just Happened?


Boy that went by fast. One minute, I’m waking up a little groggy on New Year’s Day, wondering whether the silicon industry is ever going to rebound. The next minute, it’s today and the industry had a good year, and is, in many ways, a completely different animal than it was 12 months ago. Innovation is evolutionary, sure. But if you really think about 2013, you can make an argument tha... » read more
