    摘要: A system for measuring surface features having form birefringence in accordance with the present invention includes a radiation source for providing radiation incident on a surface having surface features. A radiation detecting device is provided for measuring characteristics of the incident radiation after being reflected from the surface features. A rotating stage rotates the surface such that incident light is directed at different angles due to the rotation of the rotating stage. A processor is included for processing the measured characteristics of the reflected light and correlating the characteristics to measure the surface features. A method for measuring feature sizes having form birefringence, in accordance with the present invention includes the steps of providing a surface having surface features thereon, radiating the surface features with light having a first polarization, measuring a reflected polarization of light reflected from the surface features, rotating the surface features by rotating the surface to measure the reflected polarization of the reflected light at least one new rotated position and correlating the reflected polarization to surface feature sizes.

    摘要: The present invention relates to a method for the depth-resolved characterization of a layer of a carrier. This involves firstly producing a cutout in the layer of the carrier with a sidewall and subsequently removing carrier material adjoining the sidewall with the aid of an ion beam. During the removal process, images of the sidewall are recorded and material compositions of the removed carrier material are determined as well. A depth-resolved characterization of the layer of the carrier is carried out on the basis of a correlation of the determined material compositions of the removed carrier material with the recorded images of the sidewall, layer depths being assigned to the material compositions of the removed carrier material with the aid of the images of the sidewall. The invention furthermore relates to an apparatus for carrying out this method.

    摘要: In order to monitor the etching operation for a regular depth structure in a semiconductor substrate, a radiation source is used to irradiate, in large-area fashion, the semiconductor substrate in the region of the depth structure during the etching operation at a predetermined angle of incidence with respect to the surface of the semiconductor substrate with an electromagnetic radiation whose wavelength lies in the infrared region, a radiation detector is used to continuously detect the intensity of the reflected radiation at an angle of reflection—corresponding to the angle of incidence—with respect to the surface of the semiconductor substrate, and an evaluation unit is used to determine the depth of the etched structure and/or the quality of the etched structure with regard to the regularity thereof from the recorded intensity profile.
