The Applied Materials CENG 2 is a dry etcher used in semiconductor manufacturing.[1]
What it is
The Applied Materials CENG 2 is a dry etcher.[1]
How it works
General reference — not yet source-verifiedDry etching operates by generating a plasma from process gases inside a vacuum chamber. The plasma produces reactive species and ions that etch exposed material on the wafer, either through chemical reactions (reactive ion etching) or physical sputtering.
The system uses radio-frequency power to sustain the plasma and control etch directionality. The etch chemistry is selected based on the material to be removed, such as silicon dioxide, silicon nitride, or metals.
Where it fits in the process flow
General reference — not yet source-verifiedDry etchers are used in semiconductor fabrication after photolithography to transfer patterns into underlying layers. The etched patterns define transistor structures, interconnect lines, and other device features.
