Patent ID: 8829938

Claim:
A non-contact measuring method for characterizing a semiconductor component with at least one pn junction and one measurement area that is a front or rear side of the semiconductor component and that has at least one contacting sub-area that is covered with a contacting structure or is provided for coverage with a contacting structure, comprising the following steps: A) planar application of electromagnetic excitation radiation to the measurement area of the semiconductor component for separation of charge-carrier pairs in the semiconductor component; and, B) spatially resolved measurement of electromagnetic radiation emerging from the semiconductor component by at least one detection unit, wherein in at least one Step A, the measurement area is divided into segments by one or more of the contacting sub-areas and at least one specified excitation sub-area of the measurement area covers at least one segment and receives excitation radiation at an intensity specified for the specified excitation sub-area and at least one sink sub-area of the measurement area receives excitation radiation at an intensity that is less relative to that of the specified excitation sub-area, wherein the excitation sub-area and the sink sub-area are arranged on an opposite side of the at least one contacting sub-area and border the at least one contacting sub-area or completely or partially overlap the at least one contacting sub-area, and in at least one Step A′ excitation radiation is applied to the measurement area over a full surface and homogenously with respect to the specified radiation intensity, and a measurement according to Step B is performed at the specified sub-area of the at least one Step A and over the full surface of the at least one Step A′.
