Lithography opc
Computational lithography means the use of computers to simulate printing of micro-lithography structures. Pioneering work was done by Chris Mack at NSA in developing PROLITH, Rick Dill at IBM and Andy Neureuther at University of California, Berkeley from the early 1980s. These tools were limited to lithography process optimization as the algorithms were limited to a few square micrometres of resist. Commercial full-chip optical proximity correction, using model forms, was … Web18 mrt. 2015 · 7nm logic optical lithography with OPC-Lite Authors: Michael C.
