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 4):
The method of  claim 3 , wherein each predicted distribution corresponds to a numerical value obtained by integrating \u03b6/{(x\u2212\u03b1) 2 +(y\u2212\u03b2) 2 +(z\u2212\u03b3) 2 } \u03be/2 , which is a function of coordinates (x, y, z) of a point in the processing container and includes parameters \u03b1, \u03b2, \u03b3, \u03b6, and \u03be, about the central axis,\n wherein x, y, and z indicate the point in the processing container with respective coordinates of an X-axis, an Y-axis, and a Z-axis of an XYZ orthogonal coordinate system set to the processing container, \u03b1, \u03b2, and \u03b3 indicate a predetermined reference point on a plasma source side of the plasma processing apparatus with respective coordinates of the X-axis, the Y-axis, and the Z-axis, \u03b6 is an etching rate at the point (x, y, z) in the processing container when a length from the reference point to the point (x, y, z) is a unit length, and the parameters \u03b1, \u03b2, \u03b3, \u03b6, and \u03be are specified by actually measured values of the etching rate by etching performed under the same condition as the condition of the etching in the process.
