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.

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.

A product label includes a semiconductor chip and an antenna. The semiconductor chip stores information about a product. The antenna transmits the information about the product to a reading device. The antenna has a predetermined breaking point at which the antenna can be destroyed during the reading operation by energy introduced by the reading device so that the product label can be read only for a specific number of read cycles. A method of producing product labels and a method for a contactless, forgery-proof identification of products are also provided.

In a biometric sensor and a method for its production, a sensor chip is provided with connecting contacts in the form of electrically conductive bumps. The sensor chip is inserted into a chip housing, the bumps making contact with corresponding connecting leads belonging to the chip housing. At the same time as this contact is made, the sensor chip is bonded adhesively into the chip housing by an adhesive layer, which surrounds the sensor field in a sealing manner.

A flat carrier having a power supply, for example in the form of a coil. The carrier is characterized by an electroluminescent device that contains two flat electrodes lying above one another and an electroluminescent paste located between the electrodes. The electrodes of the electroluminescent device are connected to terminals of the power supply, which can be implemented, for example, as a coil or battery.

A copy-protection device for a semiconductor chip with a cover has a resonant oscillating circuit whose elements are located on the chip surface and within the cover. The semiconductor chip also has an evaluation circuit connected to the oscillating circuit. The evaluation circuit disables the semiconductor chip if the oscillating circuit is detuned and thus stopped from resonating. This detuning of the oscillating circuit occurs when the cover is removed, since the cover acts as a dielectric for the capacitor. After the cover has been removed, it is impossible to operate the semiconductor chip, in order to copy or analyze it.

An optoelectronic component with an optoelectronic transducer is produced with the novel method. The optoelectronic component has a coupling region, which is formed in a radiation-transparent molding of the optoelectronic component. On the base of a clearance of the coupling region, the optoelectronic component has a radiation-optical functional surface, which is formed from the housing material and introduced into the molding with the aid of a profile milling cutter.
摘要:
A configuration of a flat carrier with a chip module in a padded envelope, which can be transported in a transport device in the direction of one of the envelope's side edges, includes disposing the chip module in the padded envelope such that wire connections in the chip module extend over a side of the semiconductor chip that runs parallel to the transport device. Such a configuration is made possible by the fact that the flat carrier is applied in a standard way to a further carrier, which is folded in a suitable way.
