Description
Dry chemical diamond structuring
- mm size substrates are temporarily bonded to carrier wafers for clean room processing
- optical or electron-beam direct write lithography defines dielectric or metallic etch mask via lift-off process
- ICP etching know-how allows for tuning of sidewall geometry and angles. Deep etches beyond 50µm possible as well as free-standing nanostructures
