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 11):
An ion beam apparatus, comprising:\n an ion source; a plurality of lenses that focus ion beams emitted from the ion source; a stage that holds a sample; and a mask that is disposed on the sample and that has an opening portion, wherein the sample is irradiated with ion beams formed by being passed through the opening portion of the mask to process the sample, and the ion beam apparatus comprises a control section that exercises first control for irradiating the sample with a first ion beam among the formed ion beams to etch the sample, second control for forming a second ion beam having a magnitude of a skirt width of a longitudinal section smaller than a magnitude of a skirt width of a longitudinal section of the first ion beam, and third control for irradiating a region wider than a region irradiated with the first ion beam in a direction along a beam width, with the second ion beam to etch the sample.
