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 7):
The method of  claim 5 , wherein, in the processing container, a position of an intersection point of the central axis and an upper surface of an electrostatic chuck, which is included in the holding structure and holds the workpiece is movable along the central axis while maintaining an orientation of the upper surface,\n wherein the predicted distributions differ depending on a combination of the value of the inclination angle the condition of the etching performed in the processing container, and the position of the intersection point, and wherein the respective values of the parameters \u03b1, \u03b2, \u03b3, \u03b6, and \u03be are determined for each value depending on the value of the inclination angle and the position of the intersection point.
