DRIE-Pegasus 4 is dedicated Silicon oxide and Silicon nitride etching. It is originally designed for silicon etching but gas mass flow controllers has been changed to optimize silicon oxide and silicon nitride etching. The system is setup for 6" wafers. Sampler samples has to be bonded to a 6" carrier to be etched in the system.
