Abstract: There are several platforms for 193 nm photoresists, including chemically/non-chemically amplified photoresists, molecular glass and inorganic-organic hybrid systems. This review mainly focueses on chemically amplified photoresists due to their predominante role in industrial applications. The main components of the 193 nm chemically amplified photoresist include polymer resins, photoacid generators, additives (alkaline additives, dissolution inhibitors, etc.) and solvents. We review the current status of representative 193 nm photoresists and their main components and their advantages, disadvantages and possible development directions are also discussed.

Key words: Chemically amplified photoresist, Polymer resin, Photoacid generator, Alkaline additive, Dissolution inhibitor
