Dry Etching & Cleaning
Enhanced Solutions for Dry Etching
As the semiconductor industry continuously expands, dry etching remains a crucial process for manufacturers who need to effectively remove unwanted materials from semiconductor components. Dry etching, an eco-friendly alternative to conventional wet etching, refers to the removal of material, typically a masked pattern of semiconductor material, by exposing the material to a bombardment of ions (usually a plasma of reactive gases) that dislodge portions of the material from the exposed surface. Directed pressure under vacuum conditions allows for optimization by using gas mixtures to create a reaction that affects the wafer surface. Dry etching is a quick process that does not require much operator training.
Solvay’s innovative polymers enhance dry etching tools, while our extensive portfolio of semiconductor gases improves the dry etching and cleaning process, itself. Our unique dry etching and cleaning solutions offer a variety of performance advantages for effective semiconductor fabrication.
