Integrated circuit with an adhesive liaison offering high protection against unwanted analysis, for use in security applications for secret or confidential information storage

摘要

Integrated circuit in which some surfaces of the side supports face to face with a layer, fitted with the structures of the circuit, of a substrate and a support (1) are linked with the aid of a glue layer. The adhesive liaison consists of adhesive materials which form at least two adhesive threads (3,4). The first adhesive thread (3) is formed in the zone of the junction that one may reach at the exterior and that is found between the layer and the support and the second adhesive thread (4) extends parallel to this in the inner zone of the facing support surfaces.
