- Acetic Acid
Acetic acid is used in mixed acid etchants and in SEZ etchants. Acetic acid is used in place of water to help keep nitric acid from dissociating, which makes for a more oxidizing solutions.

- Hydrochloric Acid 37%
In semiconductor processing, the presence of metallic impurities on the wafer can lead to early dielectric breakdown. Hydrochloric acid is a key ingredient to remove surface metallic ions by forming soluble metal chlorides.
- Hydrofluoric Acid
Hydrofluoric acid is a critical chemistry in semiconductor processing. It is used to solubilize many oxides, particularly silicon dioxide, the most widely used insulator on semiconductor devices.

- Hydrofluoric Acid Dilutes
Dilute HF solutions transform a hydrophilic silicon surface to a hydrophobic surface by terminating the silicon surface with hydrogen. Dilute HF can be used to eliminate a silicon dioxide dielectric layer or to remove a metal contaminated native oxide.
