摘要: An object to be processed has a structure having an SiC film and an organic Si-low dielectric constant film formed on the SiC film. The SiC film is etched using a plasma produced from an etching gas and using the organic Si low-dielectric constant film as a mask. The etching gas contains CH2F2 or CH3F.

摘要: A method for plasma treatment etches an SiC layer with an increased etching rate and enhanced selectivities of SiC with respect to SiO2 and an organic layer. An etching gas is converted into plasma to etch SiC. The etching gas may include CHF3; CHF3 and N2, for example, a mixed gas of CHF3, N2 and Ar; or a material having C, H and F and a material having N but without any material having O.

摘要: A plasma etching method includes the steps of exciting an etching gas introduced in a processing vessel into a plasma, the etching gas including 1,1,1,4,4,5,5,5-octafluoro-2-pentyne, and carrying out a plasma etching on a film on a target object accommodated in the processing vessel via opening patterns of a resist mask on the film. Therefore, it is possible to perform plasma etching having a high selectivity to resist and/or suppressing the etch stop.
