Introduction Optical lithography is the process of creating specific patterns on semiconductor wafers using a photosensitive material (known as photoresist, PR) and an ultraviolet light exposure system to transfer patterns from masks to wafers. It is particularly recommended for use in applications where the photo-resist has seen high temperatures, strongetchants, or other harsh processing conditions. Uniform thin coatings provide improved surface conformance, improved fine-line etching performance, as well as lower costs and reduced waste. Shipley MF-319.
