Processing method using a focused ion beam










Image Number 5 for United States Patent #4457803.

A processing method using a focused ion beam is proposed which uses a focused ion beam radiation apparatus. When a specimen is irradiated with the focused ion beam in order to be etched, the desired etching depth of the specimen is preset as a function of a location. The ion dose of the focused ion beam, the acceleration voltage, or the etching time may be varied in accordance with the preset data.
