Patent ID: 7037761

Claim:
A method of producing an electronic component having a semiconductor chip with a rear side and side border regions in which the rear side and the side border regions form outer package sides, the method which comprises: providing a semiconductor wafer having a rear side and a plurality of semiconductor chips; immediately before separating individual ones of the plurality of the semiconductor chips, applying a plastic coating having a thickness in a micrometer range to the rear side of the semiconductor wafer; separating the individual ones of the plurality of the semiconductor chips to obtain separated semiconductor chips; thermally treating the separated semiconductor chips to perform a function selected from the group consisting of softening the plastic coating and melting the plastic coating; using the plastic coating on the rear side of one of the separated semiconductor chips to wet corner regions, edge regions, and side border regions of the one of the separated semiconductor chips; and completing the one of the separated semiconductor chips to form a packaged electronic component in which the rear side and the side border regions of the one of the separated semiconductor chips form outer faces of a package.
