Abstract:
1. A method of producing a blank having component positions arranged in rows and columns, the method comprising: producing semiconductor chips with flip-chip-like external contacts by providing a semiconductor wafer having a plurality of semiconductor chip positions arranged in rows and columns, in which integrated circuits are arranged, producing external contact connecting areas in the semiconductor chip positions on active upper sides of the integrated circuits, applying external contacts in the manner of flip-chips to the external contact connecting areas of a rewiring layer in the semiconductor chip positions, and dividing up the semiconductor wafer into individual semiconductor chips with flip-chip-like external contacts; applying and fixing the semiconductor chips with their flip-chip-like external contacts to an auxiliary carrier in rows and columns, maintaining a spacing between the semiconductor chips, the spacing corresponding to at least twice a saw blade thickness of a saw blade for dividing the blank into individual semiconductor components; applying a plastic compound to the auxiliary carrier, embedding semiconductor chips with their flip-chip-like external contacts; and removing the auxiliary carrier, exposing the areas of contact between external contacts and auxiliary carrier as external contact areas, wherein the auxiliary carrier used is a plastic film coated with adhesive and the external contacts of the semiconductor chips are pressed into the adhesive as the semiconductor chips are fixed to the auxiliary carrier.
