Latest Patents

One of his latest patents is a "Portable data carrier assembly comprising a security device." This invention relates to a portable data carrier system that includes a control unit, a body, and a data memory integrated in a chip. The system is designed to store security-relevant data and features a mechanism for information exchange between the control unit and an external access unit. A security device within the chip transmits a security signal influenced by an integrated feature in the body, which is not electrically connected to the security device. The system includes a detection feature that identifies the influenced security signal, an evaluation feature that assesses it, and a blocking feature that prevents a security-critical operating state if the expected security signal is not recognized.

Another significant patent is for a "Circuit suitable for vertical integration and method of producing same." This invention introduces a vertically integratable circuit and a method for its production. Unlike traditional methods, this approach utilizes process steps during the production of the circuit itself, allowing for vertical integration. This innovation simplifies the production sequence for vertically integratable circuits, optimizing plant running times and improving yield by eliminating unnecessary process steps that could alter already produced active circuit elements.
