Patent ID: 8563358

Claim:
A method of producing a chip package, comprising: providing a substrate comprising a recess having a recess bottom and recess side walls in a first surface introducing a chip, which has a chip backside, into the recess such that the chip does not protrude from the recess and that a gap remains between the recess side walls and the chip, the chip backside being attached to the recess bottom; and filling the gap with a filler material, wherein the substrate comprises a flexible one-layer or multi-layer film-roll substrate, wherein the chip comprises a flexible semiconductor chip having a thickness which ranges from 10 μm to 50 μm, wherein a frontside of the chip, which is opposite the backside of the chip, is set back in relation to the first surface of the substrate, filling the gap comprising filling the recess and providing filler material on the frontside of the chip, the method further comprising patterning the filler material arranged over the frontside of the chip so as to expose at least one contact area on the frontside of the chip, wherein a photomask is used for exposing the at least one contact area, adjustment of the photomask being effected on the basis of edges and/or corners of the recess filled with the filler material, on the basis of a position of the at least one contact area, or on the basis of corners of the chip.
