Understanding Photoresist in Semiconductor Manufacturing

Source: Semiconductor Industry Observation Photoresist, also known as photoresist agent, is a light-sensitive liquid mixture. Its components include: photoinitiators (including photosensitizers and photoacid generators), photoresist resin, monomers, solvents, and other additives. Photoresist can transfer the required fine patterns from a photomask (mask) to the substrate to be processed through photochemical reactions and photolithography processes such … Read more
