WebOptical lithography (also known as photolithography) is a technique based on transferring a pattern from a mask to a surface using a radiation source, such as visible UV light or X-rays. For this process, a photosensitive material is exposed through a photomask and the exposed areas suffer a change on its chemical properties. WebLithography is the process of transferring patterns of geometric shapes on a mask to a thin layer of radiation-sensitive material (called resist) covering the surface of a semiconductor wafer. 1 These patterns define the various regions in an integrated circuit such as the implantation regions, the contact windows, and the bonding-pad areas. income tax new regime and old regime
