Abstract:
A sufficient processing speed and sufficient processing accuracy are obtained in a microstructure manufacturing method using ion beams. The microstructure manufacturing method includes the steps of: (a) irradiating a first region of a sample with a first ion beam (projection ion beam) formed by being passed through a first opening portion of a first mask, and etching the sample; and (b) irradiating a second region that is wider than the first region in a direction along a beam width, with a second ion beam (projection ion beam), and processing the sample. Furthermore, a magnitude of a skirt width of a longitudinal section of the second ion beam is smaller than a magnitude of a skirt width of a longitudinal section of the first ion beam.

Claim (Index 12):
The ion beam apparatus according to  claim 11 , wherein\n the opening portion is formed from a plurality of types of shapes, the plurality of types of shapes of the opening portion are similar, and the control section exercises control such that the first ion beam is formed by being passed through a first opening portion among the plurality of types of shapes of the opening portion, and that the second ion beam is formed by being passed through a second opening portion having a larger area than an area of the first opening portion.
