Process materials (gases and chemicals)
Which set correctly lists the main kinds of process materials used in semiconductor manufacturing?
- AWafers, gases, wet chemicals, photoresist, sputtering targets, CMP slurries and so on
- BWood, paper and cloth
- CGasoline, diesel and kerosene
Show answer and explanation
Answer: A. Wafers, gases, wet chemicals, photoresist, sputtering targets, CMP slurries and so on
Besides the wafers that serve as substrates, semiconductor manufacturing uses many high-purity materials: gases for deposition and etching, chemicals for cleaning and etching, photoresist for exposure, sputtering targets, and CMP slurries and pads.
- A. Correct. Wafers, gases, chemicals, resist, targets, slurries and so on.
- B. Wood, paper and cloth are not semiconductor process materials.
- C. Fuels are not process materials.
