Description
Controlled dry anisotropic etching of silicon wafers up to 6 inches in diameter utilising the Bosch process. The deep silicon etching (DSE) process alternates between deposition and isotropic etching in a chamber with an ICP configuration.
-
Related Information
Etching of silicon only.
The deposition gas is typically C4F8 and the etching gas is commonly SF6.
Gases available: SF6, C4F8, argon and oxygen.
Substrate is 6 inch wafer.
Fast silicon etch rate of 3 – 5 µm/min with a deep vertical wall.

Description
Silicon-specific dry etching with good control over feature size and Bosch process capability for high aspect ratio structures.
