Patent ID: 8302870

Claim:
A personal document having an integrated readable chip that can be read in a contactless manner, comprising: a laminate that comprises at least one chip film including a chip having a thickness of d≦50 μm, a substrate covering the chip film on a structural side of the chip, and a cover layer covering the chip film on a back side of the chip, the chip including an integrated circuit; wherein the chip film comprises the chip and polymer carrier film layers that, except for contact connectors of the chip, are applied to the structural side of the chip and to the back side of the chip; the chip is joined on each of the structural side and the back side of the chip to the polymer carrier film layers by a coupling reagent possessing a first chemical functional group that reacts with a semiconductor material on a surface of the chip to form a covalent bond therewith, and which coupling reagent possess a second chemical functional group that reacts with a polymer matrix of the polymer carrier film layers; the polymer carrier film layers, the substrate, and the cover layer each comprise compatible polymers that are miscible with one another; and the chip is joined to an antenna provided on the substrate.
