Webgeneral, modern photolithography involves a procedure with five steps; wafer preparation, application of photoresist, pre-exposure bake, exposure, post-exposure bake, and development. In photolithography, a wafer is a thin slice of semi conductive material, such as crystalline silicon, that forms the base for the photolithographic process.
Webthe development rates calculated with the DRM are not representative of production. A wish list for photolithography development rate measurements might look like this. 1) An in-situ measurement of the development rate of exposed regions on a patterned wafer. 2) A polychromatic sample of the resist thickness interference.
