Lithography sraf
WebAn accurate method of SRAF printing prediction is important to assure that no SRAFs are actually printed. SRAF has evolved from a simple shape of narrow line to more complex … Web(SRAF) generation is used to improve the lithographic process window of target patterns. These assist features are not actually printed; instead, the SRAF patterns would deliver …
