Reducing Transistor Variability For Higher-Performance, Lower-Power Chips 
Peer-reviewed Contributed Article
March/April 2013
IEEE Micro Magazine 

CMOS integrated-circuit, supply-voltage reduction has plateaued in recent years as increased transistor variability has limited transistor-threshold voltage scaling. The deeply depleted channel transistor, implemented on bulk CMOS, provides a low-cost option to re-enable voltage scaling on both future and legacy CMOS fabrication processes by reducing random variability and providing a strong body factor to pull in systematic variation and compensate for environmental effects resulting in 50 percent lower power at matched performance.

System-on-chip technology comes of age
5 October, 2012

SoC technology has been used by fabless vendors and foundries for well over a decade. But it is the rapid proliferation of mobile post-PC products that is proving to be the catalyst for this technology to finally realize its full disruptive potential. Within the last five years, SoC technology has moved from being at the heart of smartphones to enabling tablets and full feature mobile computers like ultrabooks. This article describes the emerging importance of the SoC, its likely technological evolution and its potential impact on the semiconductor industry in a mobility driven age. Read more.

How Power Consumption and Cost Impact Moore's Law and More-than-Moore Roadmaps
September 2012

The semiconductor industry needs an economically sensible roadmap that addresses the excessive cost of 20nm and smaller process technologies. This article argues that the semiconductor process technology roadmap should now be split in two: a roadmap with the classical “Moore’s Law” benefit of greater density from shrinking, and a “More-than-Moore” roadmap that enhances the capability of a given process technology by reducing power consumption. Read more.

Video Interview with industry analyst Dan Hutcheson
25 June 2012

Leading-edge process technology is not economically feasible for a majority of semiconductors, but 'Everything Mobile' has put pressure on every technologist to advance their designs into lower power regimes. In a world where battery life is everything, reducing power consumption is a top priority for every chip company. In this video, we discuss how this can be done with some fairly simple process modifications. View video.

Rethinking the pursuit of Moore's Law
20 June 2012

There is much excitement about the semiconductor industry moving to 28nm and 20nm process technology. For a majority of products, however, it will be several years before these leading-edge process technologies make economic sense. These products will remain on mature process technologies, getting none of the benefits that Moore’s Law brings. What if there was another way? What if you could extend the capabilities of mature technologies without having to overcome the cost wall of a shrink to the leading edge?

This article argues that the benefits of Moore’s Law can now be split in two: the classical benefits of greater density and lower cost-per-transistor from shrinking, and the benefit of extending the capability of mature process technology generations by reducing power consumption.  Read more.

How Will the Chip Wars be Won? - Part 2
16 February 2012 

As silicon CMOS enters its fifth decade, the industry once again finds itself at a crossroads. At this juncture, the future of CMOS scaling will be defined not only by fundamental device architecture and materials innovations but also the evolving chip landscape. New alliances, players and market segments with radically different cost structures will play a role in determining the future course of the semiconductor industry and the evolution of the semiconductor fabrication process.

Part 1 of this article highlights the emerging importance of the mobile SoC and its impact on the industry landscape and the continued evolution of Moore’s Law.

Part 2 discusses why the new landscape favors an open foundry and design ecosystem and identifies trends that are likely to define the semiconductor industry over the next decade.
