Development photolithography
Web1 Answer. Photolithography is the process of transferring geometric shapes on a mask to the surface of a silicon wafer. The steps involved in the photo-lithography process are wafer cleaning barrier layer, formation photo-resist applications soft baking, mask alignment, exposure and development and hard baking.
