Photolithography processing
WebA stepper is a device used in the manufacture of integrated circuits (ICs) that is similar in operation to a slide projector or a photographic enlarger. Stepper is short for step-and-repeat camera. Steppers are an essential part of the complex process, called photolithography, which creates millions of microscopic circuit elements on the ... WebFor photolithography processing SNF houses three types of UV exposure tools: contact aligner, direct write (mask-less) system, and a stepper. All of these systems utilize near-UV sensitive photoresist for pattern transfer. Selection of the appropriate exposure tool depends upon the specifics of the project. Listed in each tool’s webpage specific …
