Photolithography is a key process in semiconductor fabrication. It is used to transfer geometric patterns from a photomask onto a light-sensitive chemical resist on the surface of a semiconductor wafer. This patterned resist then acts as a mask for subsequent etching or deposition steps, building up the complex layers of the integrated circuit.
Integrated chip is produced on a piece of semi-conductor crystal by the process of A) Embedding B) Photolithography C) Tomography D) Cryptography
