“Inverse lithography technology (ILT) represents the most significant EDA advance in the last two decades.”  Danping Peng from TSMC made that assertion at the recent SPIE Advanced Lithography + Patterning Conference, in his talk entitled:  ILT for HVM:  History, Present, and Future.  This article summarizes the highlights… Read More


Magic? No! It’s Computational Lithography

Magic? No! It’s Computational Lithography

The industry plans to use 193nm light at the 20nm, 14nm, and 10nm nodes. Amazing, no? There is no magic wand; scientists have been hard at work developing computational lithography techniques that can pull one more rabbit out of the optical lithography hat.

Tortured metaphors aside, the goal for the post-tapeout flow is the same… Read More
