    摘要: The invention relates to a tamper-resistant semiconductor device comprising a substrate (5) comprising an electronic circuit arranged on a first side thereof. An electrically-conductive protection layer (50, 50a, 50b) is arranged on a second side of the substrate (5) opposite to the first side. At least three through-substrate electrically-conductive connections (45) extend from the first side of the substrate (5) into the substrate (5) and in electrical contact with the electrically-conductive protection layer (50, 50a, 50b) on the second side of the substrate (5). A security circuit is arranged on the first side connected to the through-substrate electrically-conductive connections (45) and is arranged for measuring at least two resistance values (R12, R23, R34, R14, R13, R24) of the electrically-conductive protection layer (50, 50a, 50b) through the through-substrate electrically-conductive connections (45). The security circuit is further arranged for comparing the measured resistance values (R12, R23, R34, R14, R13, R24) with reference resistance values.

    摘要: A semiconductor device in which a capacitor (2) is provided on a surface (10) of a semiconductor body (3) with a semiconductor element (1) in which a lower electrode (11), an oxidic ferroelectric dielectric (12) and an upper electrode (13) are provided in that order, the upper electrode not covering an edge of the dielectric, after which an insulating layer (14) with superimposed metal conductor tracks is provided. According to the invention, the edge of the dielectric (12) not covered by the upper electrode (13) is coated with a coating layer (14, 20, or 30) practically imperviable to hydrogen, after which the device is heated in a hydrogen-containing atmosphere. Heating in a hydrogen atmosphere neutralizes dangling bonds which arise during deposition of the conductor tracks on the insulating layer, while the coating layer protects the dielectric from attacks by hydrogen. The semiconductor device then has a shorter access time.

    摘要: A method of manufacturing a semiconductor device is set forth comprising a semiconductor body (1) having a surface (2) adjoined by a semiconductor region (3) and a field oxide region (4) surrounding this region, on which surface (2) is provided a metal layer (13), in which a conductor track (17, 18) is formed, after which an isolating layer of silicon oxide (19) is deposited over the conductor track (17, 18) on the surface (2). According to the invention, before the layer of silicon oxide (19) is provided over the conductor track (17, 18), this track is provided with a top layer (16) of an oxidation-preventing material. By providing this top layer (16), it is avoided that the conductor track (17, 18) covered by silicon oxide (19) has a high electrical resistance or even an electrical interruption.
