Etching (microfabrication)

ID: etching-microfabrication

Etching is a crucial process in microfabrication, which is the technology used to create structures on the microscale, often for semiconductor devices and microelectromechanical systems (MEMS). Etching involves selectively removing material from a substrate to create patterns, structures, or features. There are two primary types of etching processes: wet etching and dry etching. 1. **Wet Etching**: - This process uses liquid chemicals or etchants to remove material from a substrate.
