Abstract:
A device for detecting the spatial distribution of properties of a sample having a surface n, the device comprising in combination:a microscope, the microscope provided with a control for a three-dimensional detection of the topography zn(x,y) of the surface n of the sample; a probe, the probe provided with a control for a spatially resolved detection of one or several properties Pj of the sample on the topography zn(x,y) of the surface n; an ablating device for etching with reactive gases or fluids or for chemimechanical polishing, and for removing a layer of the entire surface n of the sample in one ablating step An,n+1, wherein the ablating device is provided with a control; and a computer-assisted image processing device, the image processing device producing a three-dimensional image of the sample n from a sequence of surface topographies zn(x,y) to zn+m(x,y) and for the properties Pj (zn(x,y)) to Pj (zn+m(x,y)) detected on these topographies by the microscope, wherein the image processing device is provided with a control.
