Abstract:
Silicon nitride plasma etching processes are disclosed that minimize the SiN roughness layer on a substrate having a SiN layer thereon by simultaneously introducing an oxidizer at a predetermined flow rate and an etch gas into a plasma reaction chamber containing the substrate. The etch gas has the formula C x H y F z , wherein x is 2-5, z is 1 or 2, 2x+2=y+z, and a fluorine atom is located on a terminal carbon atom of the etch gas.

Claim (Index 17):
The method of  claim 1 , wherein the substrate is selected from the group consisting of silicon, polysilicon, silicon oxide, SiGe, Ge, GaAs, InGaAs, InP, InAs, or combinations thereof.
