FinFET & Multi-patterning Need Special P&R Handling

FinFET & Multi-patterning Need Special P&R Handling
by Pawan Fangaria on 04-28-2014 at 1:00 pm

I think by now a lot has been said about the necessity of multi-patterning at advanced technology nodes with extremely low feature size such as 20nm, because lithography using 193nm wavelength of light makes printing and manufacturing of semiconductor design very difficult. The multi-patterning is a novel semiconductor manufacturing… Read More

Image RemovedI’ll bet you’ve read a bunch of stuff about double patterning, and you’re probably hoping that the design tools will make all your double patterning issues just go away. Well, the truth is that the foundries and EDA vendors have worked really hard to make that true.

However, for some critical portions of your … Read More

David Avercrombie of Mentor won the award for the best tutorial at the 2012 TSMC OIP for his presentation, along with Peter Hsu of TSMC, on Finding and Fixing Double Patterning Errors in 20nm. The whole presentation along with the slides is now available online here. The first part of the presentation is an introduction to double … Read More


Double Patterning Verification

Double Patterning Verification

You can’t have failed to notice that 20nm is coming. There are a huge number of things that are different about 20nm from 28nm, but far and away the biggest is the need for double patterning. You probably know what this is by now, but just in case, here is a quick summary.

Lithography is done using 193nm light. Today we use immersion… Read More
