Abstract

A method for producing a document structure, wherein the method includes producing a chip structure by forming a cavity in a carrier having a top side and an under side, picking up a chip having at least one chip contact and a redistribution layer (RDL) connected to the at least one chip contact by means of a picking-up device detaching the chip from an auxiliary carrier, wherein the chip bears on the auxiliary carrier by way of the RDL, wherein the chip is lifted up from the auxiliary carrier by means of pressure being exerted on the RDL, wherein the lifted-up chip is picked up and inserted into the cavity, and wherein the RDL is oriented on the top side of the carrier, fixing the chip in the cavity by means of an adhesive, electrically conductively connecting the at least one chip contact of the RDL to an electrically conductive region of the carrier by means of an electrically conductive material, and embedding the carrier between a first paper layer and a second paper layer.
