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(φ, 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 φ 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.

Claim (Index 3):
The method of  claim 1 , wherein a plurality of predicted distributions of the etching rate on the surface of the workpiece are acquired in advance before execution of the process,\n wherein the predicted distributions differ depending on a combination of the value of the inclination angle and a condition of etching performed in the processing container, wherein the etching rate, obtained by each of the plurality of inclined rotation states, corresponds to one of the plurality of predicted distributions, wherein the process time of each of the plurality of inclined rotation states is indicated by a weighting value given to the predicted distributions, and wherein, among the plurality of predicted distributions, a plurality of predicted distributions having the same condition as the condition of the etching performed in the step and a weighting value of each of the plurality of predicted distributions are specified before the step, the plurality of inclined rotation states are specified using the value of the inclination angle of each of the plurality of specified predicted distributions and the weighting value, and the plurality of specified inclined rotation states are implemented in the step.
