  • Patent number: 10685816
    Abstract: A method MT includes etching a wafer W using plasma generated in a processing container. The etching includes a process of inclining and rotating a holding structure holding the wafer W during execution of the etching and the process successively creating a plurality of inclined rotation states RT(?, t) with respect to the holding structure. In the inclined rotation states, the wafer W is rotated about a central axis of the wafer W over a predetermined process time while maintaining a state where the central axis is inclined with respect to a reference axis of the processing container which is in the same plane as the central axis. A combination of a value ? of an inclination angle AN of the central axis with respect to the reference axis and the process time t differs for each of the plurality of inclined rotation states.
