A carrier element for a semiconductor chip and in particular for incorporation into smart cards. The carrier element has an encapsulation composition protecting the semiconductor chip. The carrier element connections are disposed on one of the main surfaces of the encapsulation composition along only two opposite edges. They are made of a conductive material and have a reduced thickness at the ends facing one another, the cross section having a step only on one side. The semiconductor chip is disposed on the connections in a region of the section of reduced thickness and is mechanically connected to the connections.

A smart-card module is described which has a substrate film of an anisotropically conductive material and at least one semiconductor chip. The semiconductor chip has connection points. On one surface of the semiconductor film, contact areas are applied directly. The substrate film is disposed between the semiconductor chip and the contact areas in such a way that it connects the connection points of the semiconductor chip to the contact areas in a manner of a direct contact.

A chip card with a chip module having an integrated circuit and, for external contacting, has on a main face a contact zone with a number of contact areas which are spaced apart from one another and are electrically connected to the integrated circuit. At least one contact area is made up of first functional regions with first surfaces and of second functional regions with second surfaces, and the first surfaces of the first functional regions lie higher with respect to the main face than the second surfaces of the second functional regions.

A smart card is laminated from at least two layers of paper or film as a mounting material. A first of the layers is fitted with a semiconductor chip and a second layer has connecting contacts as well as conductor tracks or external connecting surfaces. The contacts of the semiconductor chips are electrically conductively connected to the connecting contacts on the second layer. No chip modules are required to produce the smart cards. The mounting materials provided with ICs and contacts can be laminated in an endless roll format, in the same way as for paper production.
摘要:
A method for producing a chip module includes punching a chip carrier to form a chip carrier fixing section and chip carrier contact sections spaced apart from the chip carrier fixing section by slots defining a given distance. The given distance is subsequently reduced to a dimension preventing a flow through of a sealing mass by a swaging operation carried out at least in a region close to the slots.

A portable data carrier includes a card-shaped body having a recess for receiving a chip module. The chip module includes at least one semiconductor chip on a first main side of a chip carrier connected to the card-shaped body, and a metallization layer disposed on a second main side of the chip carrier and having contact lugs. The chip carrier has desired bending points which, upon the occurrence of bending stresses, reduce forces on the semiconductor chip and wire connections.
摘要:
A smart card with a card carrier on which a data processing circuit and also a connection assembly for the contactless communication of data between the data processing circuit and an external data processing station are provided. In the course of producing a prior art smart card, an integrated circuit is applied to a card carrier made of plastic. Afterwards, a transmitting/receiving coil connected to corresponding terminals of the integrated circuit is applied along the outer edges of the prior art smart card. In the case of the prior art smart card, the fact that defective prior art smart cards have to be destroyed is disadvantageous. According to the invention, the data processing circuit and the connection assembly are provided in a region of at least one module carrier and the card carrier has a region for accommodating the module carrier. This makes it possible firstly to test the completed module carrier in respect of its proper functioning before it is incorporated into a card carrier.
摘要:
Flip-chip bumps (solder bumps) are applied on the contact-connection points of a semiconductor chip. These bumps extend from there through a covering compound (mold) that is applied as a protective layer. The end of each one of the bumps that is remote from the semiconductor chip forms a pad. This pad lies approximately plane-parallel in the surface of the covering compound that is remote from the semiconductor chip. At least during the encapsulation process, the chips are preferably arranged on a carrier element, in particular a carrier strip.
