Abstract:
1. A method for producing an integrated circuit, comprising the steps of: providing a semiconductor substrate having a first lateral dimension and having a first substrate surface and a second substrate surface arranged substantially parallel to the first substrate surface, producing circuit structures in the semiconductor substrate using lithography process steps, providing a first flexible film piece having a second lateral dimension which is greater than the first lateral dimension, and having a recess in the lateral dimension, said first flexible film piece further having a first film piece surface and a second film piece surface which is arranged substantially parallel to the first film piece surface, arranging the semiconductor substrate and the first flexible film piece on a holding body, with said semiconductor substrate being positioned in the recess, encapsulating the second substrate surface and the second film piece surface with a potting material in order to form a combined film, chip, detaching the film chip from the holding body, and producing a patterned layer of an electrically conductive material above the semiconductor substrate and the first flexible film piece using lithography process steps, wherein the patterned layer extends from the semiconductor substrate to the first flexible film piece and forms a number of electrically conductive contact tracks between the semiconductor substrate and the first film piece, wherein the first substrate surface and the first film piece surface are arranged on the holding body in a plane-parallel fashion in order to orient the first substrate surface and the first film piece surface in plane-parallel fashion, wherein the combined film chip is detached from the holding body such that the plane-parallel first substrate surface and first film piece surface are directly accessible, and wherein the patterned layer is produced directly on the semiconductor substrate and the first flexible film piece such that the semiconductor substrate and the film piece are electrically connected without contact holes.
