Abstract:
A method for selectively etching an etch layer with respect to a mask is provided. An etch process is provided comprising a plurality of etch cycles, wherein each etch cycle comprises providing a deposition phase and an etch phase. The deposition phase comprises providing a flow of a deposition phase gas, comprising a fluorocarbon or hydrofluorocarbon containing gas and an oxygen containing gas with a fluorocarbon or hydrofluorocarbon to oxygen ratio, providing a RF power, which forms the deposition phase gas into a plasma, and stopping the deposition phase. The etch phase, comprises providing a flow of an etch phase gas, comprising a fluorocarbon or hydrofluorocarbon containing gas and an oxygen containing gas with a fluorocarbon or hydrofluorocarbon to oxygen ratio that is lower than the fluorocarbon or hydrofluorocarbon to oxygen ratio of the deposition phase gas, providing a RF power, and stopping the etch phase.

Claim (Index 14):
The method, as recited in  claim 12 , wherein the etch partially etches the etch layer to a target depth.
