WebDuring the manufacturing of integrated circuits yield loss is caused for example by defects, faults, process variations, and design. During processes as implantation, etching, deposition, planarization, cleaning, lithography, etc. failures responsible for yield loss are observed. WebFollowing is a step by step overview of the basic lithography process from substrate preparation through developing of the photoresist image. It should be noted that the addition of anti-reflective coatings, lift-off layers, image reversal steps, etc. can add significant levels of complexity to the basic process outline shown below.
