Optical endpoint detection on the dry etch tools at DTU Nanolab
Several dry etch tools at DTU Nanolab are equipped with an endpoint detection system. Out of those systems only one is not of the type optical endpoint detection. The instruments are:
- ICP Metal Etch
- III-V ICP
- Pegasus 1
- Pegasus 4
