diyhpl.usLithography Using ASML Stepper Page 4 INTRODUCTION Overlay (alignment) is as important as resolution in lithography. Modern CMOS integrated circuits have ~ 30 layers to be aligned. The RIT SUB-CMOS processes use up to 15 layers. Alignment marks are placed on the wafer at the beginning of the process
