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. Webwhich is more robust to mask defects. • Mask size can get unwieldy for large wafers. • Most wafers contain an array of the same pattern, so only one cell of the array is needed on the mask. This system is called Direct Step on Wafer (DSW). These machines are also called “Steppers” • Example: GCA-4800 (original machine)
