Web20 languages. Tools. A photoresist (also known simply as a resist) is a light-sensitive material used in several processes, such as photolithography and photoengraving, to form a patterned coating on a surface. This process is crucial in the electronic industry. [1] The process begins by coating a substrate with a light-sensitive organic material.

Lithography, which is also called optical lithography or UV lithography, is a process used in microfabrication to pattern parts of a thin film or the bulk of a substrate. It uses light to transfer a geometric pattern from a photomask to a light-sensitive chemical "photoresist", or simply "resist," on the substrate. the range xmas outdoor decorationsWebEtching is a critically important process module, and every wafer undergoes many etching steps before it is complete. For many etch steps, part of the wafer is protected from the etchant by a "masking" material which resists etching. In some cases, the masking material is a photoresist which has been patterned using photolithography. the range yarnWebFor the man production of the LSI and VLSI the following methods are available. 1) Ultraviolet (UV) optical direct-step on wafer litho-graphic process or Optical Lithography. … the range wrexham telephone numberWeb1 Answer.
