Claim 0:
1. A method, comprising:
a) providing a sample comprising a region of interest;
b) producing a macrolamella comprising the region of interest by removing material from the sample using a first particle beam so that first and second cross-sectional surfaces of the sample are exposed, the first and second cross-sectional surfaces being opposite one another and spaced apart from one another, and the region of interest of the sample being between the first and second cross-sectional surfaces;
c) orienting the macrolamella relative to a processing particle beam so that the processing particle beam and a selected cross-sectional surface form an angle of from 10° to 90° with respect to one another, the processing particle beam being selected from the group consisting of the first particle beam and a second particle beam, and the selected cross-sectional surface being selected from the group consisting of the first cross-sectional surface and the second cross-sectional surface; and
d) producing a microsample comprising the region of interest by removing material from the macrolamella using the processing particle beam,
wherein, during b), only the first particle beam is used to remove material from the sample to produce the macrolamella.
