Abstract:
The invention relates to a method for producing a portable data carrier, for example a chip card. The method is characterized in that a spatial structure (6) is printed onto a first foil (2). Electrically conductive lines (12) are first applied to the structure (6), by spraying or casting for example, and components (14), such as a chip and an antenna coil for example, are then inserted into the structure (6), said structure (6) corresponding to the dimensions or the shape and size of the inserted components (14). In the process, the components (14) are connected to the lines (12) in an electrically conductive manner. A cover (16) is printed over the components (14). A second foil (18) can be applied onto the cover (16), and a printed design (4, 20) can be applied onto the two foils (2, 18). Additionally, a recess can be introduced into the structure (6) and the foils (2, 18) in order to insert a chip module (22) for example.
Abstract:
A method of producing a substrate (300) with an embedded chip (110) is disclosed. This method comprises a first step of mounting a semiconductor chip (110) on a first substrate (100A) on which a first wiring (103A,103B)) is formed; and a second step of joining the first substrate (100A) with a second substrate (200) on which a second wiring (203A,203B) is formed. In the second step, the semiconductor chip (110) is encapsulated between the first substrate (100A) and the second substrate (200) and electrical connection is made between the first wiring (103A) and the second wiring (203B) so as to form multilayered wirings connected to the semiconductor chip (110). The encapsulation may occur by injection moulding. The first and second substrates (100A,200) may contain an electromagnetic shield layer (100P,200P).
