Selective nitride etch

Methods of selectively etching silicon nitride are provided. Silicon nitride layers are exposed to a fluorinating gas and nitric oxide (NO), which may be formed by reacting nitrous oxide (N2O) and oxygen (O2) in a plasma. Methods also include defluorinating the substrate prior to turning off the pla...

Abstract Methods of selectively etching silicon nitride are provided. Silicon nitride layers are exposed to a fluorinating gas and nitric oxide (NO), which may be formed by reacting nitrous oxide (N2O) and oxygen (O2) in a plasma. Methods also include defluorinating the substrate prior to turning off the plasma to increase etch selectivity of silicon nitride.
