Abstract:
A method for processing a semiconductor wafer is provided. A semiconductor wafer includes a first main surface and a second main surface. Defects are generated inside the semiconductor wafer to define a detachment plane parallel to the first main surface. Processing the first main surface defines a plurality of electronic semiconductor components. A glass structure is provided which includes a plurality of openings. The glass structure is attached to the processed first main surface, each of the plurality of openings leaving a respective area of the plurality of electronic semiconductor components uncovered. A polymer layer is applied to the second main surface and the semiconductor wafer is split into a semiconductor slice and a remaining semiconductor wafer by cooling the polymer layer beneath its glass transition temperature along the detachment plane. The semiconductor slice includes the plurality of electronic semiconductor components.
