Coventor, Lego and IoT in Denmark

Coventor, Lego and IoT in Denmark
by Paul McLellan on 04-17-2015 at 7:00 am

Coventor were in Copenhagen Denmark a few weeks ago at the Smart Systems Integration Conference to talk about MEMS and IoT entitled (take a deep breath) Towards a Lego Block Principle for Heterogonous Systems Design Including MEMS and Electronics—Choose and Put Together Fit. Since this seems to have become IoT week for me, without… Read More


Vertical NAND Flash

Vertical NAND Flash
by Paul McLellan on 03-23-2015 at 7:00 am

You may know that up until now NAND flash has been a planar technology. But just as with SoC processes where we have had to go vertical to FinFETs, NAND flash has reached the limitations of scaling in the 20nm nodes and is also going vertical. It is not just a lithography issue but there are also reliability and voltage scaling issues.… Read More


Mapping Focus and Dose onto BEOL Fabrication Effects

Mapping Focus and Dose onto BEOL Fabrication Effects
by Tom Simon on 03-16-2015 at 7:00 pm

With today’s ArF based lithography using 193nm wavelength light, we are hard up against the limitations imposed by the Raleigh equation. Numerous clever things have been devised to maximize yield and reduce feature size. These include 2 beam lithography, multiple patterning, immersion litho processes to improve NA, thinner… Read More


IoT Sensor Node Designs Call for Highly Integrated Flows

IoT Sensor Node Designs Call for Highly Integrated Flows
by Tom Simon on 02-21-2015 at 7:00 pm

Applications for IoT sensors are becoming more sophisticated, especially for industrial usage. Building optimal sensors for different applications requires multi-domain design, optimization and verification flows. The sensor devices are usually MEMS, and as such have electrical properties that need to be tailored to … Read More


Chips Are Going 3D, DRC Needs to Go 3D Too

Chips Are Going 3D, DRC Needs to Go 3D Too
by Paul McLellan on 02-10-2015 at 7:00 am

The last paradigm shift in DRC was around 0.35um when designs got too large to handle as flat data, and hierarchical approaches were required. Back then the design rules themselves were not that complex, the explosion of data volume came from the complexity of the design itself. But each process node added more design rules intricacies… Read More


Coventor Panel at IEDM Digs into Variation Issues

Coventor Panel at IEDM Digs into Variation Issues
by Tom Simon on 01-05-2015 at 7:00 pm

Recently I attended a panel discussion on variability in semiconductor fabrication hosted by Coventor in conjunction with the IEEE IEDM conference in San Francisco. The IEEE bills the conference as “the world’s pre-eminent forum for reporting technological breakthroughs in the areas of semiconductor and electronic device… Read More


Variation: How Can We Survive?

Variation: How Can We Survive?
by Paul McLellan on 12-24-2014 at 12:57 pm

At IEDM last week Coventor hosted a panel session as they do each year. The theme this year was surviving variation. The panel was hosted by someone whose name is familiar round here, Dan Nenni. The panel that Coventor had put together had people from all sorts of different slots in the design/supply chain for semiconductor. Unfortunately… Read More


Intel has Another First for 14nm Production!

Intel has Another First for 14nm Production!
by Daniel Nenni on 12-10-2014 at 7:00 am

An interesting thing happened while I was researching a slide from Bill Holt’s “Advancing Moore’s Law” presentation at last month’s analyst meeting. Slide #19 mentioned that Intel was the first to use “air gap” dielectric spaces to improve performance in a digital logic flow for microprocessors. I know a certain foundry that … Read More


Variation at IEDM

Variation at IEDM
by Paul McLellan on 12-05-2014 at 7:01 am

IEDM (technically the International Electron Devices Meeting although I’ve never heard anyone use the full name) is in a couple of weeks time, in San Francisco. It is December 15-17th at the Hilton Union Square (which is not actually at Union Square but nearby at 333 O’Farrell Street).

For the last few years on the Tuesday… Read More


What makes the world smart?

What makes the world smart?
by Pawan Fangaria on 11-25-2014 at 4:00 pm

The simple answer is when everything in the world is smart. But if you think deeply, you would find that the continuous progression to make things easy in life is what makes the world smarter day-by-day – the sky is the limit. In the world of computing, consider the 17[SUP]th[/SUP] century era when humanbrain was used as a computer … Read More
