  • Final Report | Exhaust Gas Monitoring for Process Control

    During the recovery from this process, a series of SF6/O2/Cl2 plasmas are struck in the chamber without a wafer, followed by a series of bare and polysilicon wafer etches and chamber cleans. The conservative recipe for this recovery was developed to ensure consistent conditioning of the chamber in preparation for etching of production wafers.
