Further, 60-MHz technology reduces voltage potential across the plasma sheath, minimizing ion etch damage, and thus improving film quality and yields.
This model includes a complete treatment of the time-dependent ion kinetics in the plasma sheath, the thin region between the plasma and the substrate surface.
The new hardware targets the shape of the plasma sheath, the electron energy and other key parameters to improve performance.
