WebPhotolithography is the most critical process step in device fabrication. The main goal of photolithography is to replicate a pattern representing an integrated circuit component on the wafer surface. In this lab you will simulate the four key stages of photolithography that are typically carried out in an IC fabrication: Surface preparation WebStep 3 – Chrome Process for glass and quartz photomasks fabrication. The quartz / glass (substrate) has a layer of chrome on one side. The chrome is covered with an AR (anti-reflective) coating and a photosensitive resist. The photomask substrate with chrome, AR, and resist is known as a blank photomask. The blank photomask is placed on the ...
