Abstract
The invention relates to a personal document that can be read contactlessly and which includes a laminate having a chip film and a chip, a substrate covering the chip film on the structure side of the chip and a covering layer covering the chip film on the rear side, the chip having an integrated circuit, said chip being thinned to the thickness defined herein. The personal document includes a polymeric carrier film that connects to the chip through a coupling reagent possessing functional groups compatible with functional groups of the semiconductor material of the chip and of the polymer carrier film layers of the chip film. Also, the chip is connected to an antenna provided on the substrate.
