  • Patent number: 10249583
    Abstract: A semiconductor die includes a last metallization layer above a semiconductor substrate, a bond pad above the last metallization layer, a passivation layer covering part of the bond pad and having an opening that defines a contact area of the bond pad, an insulating region separating the bond pad from the last metallization layer at least in an area corresponding to the contact area of the bond pad, and an electrically conductive interconnection structure that extends from the bond pad to the upper metallization layer outside the contact area of the bond pad. Corresponding methods of manufacture are also provided.
    Type: Grant
    Filed: September 19, 2017
    Date of Patent: April 2, 2019
    Assignee: Infineon Technologies AG
    Inventors: Christian Bretthauer, Bernhard Laumer, Holger Poehle, Momtchil Stavrev

  • Patent number: 7851362
    Abstract: In order to reduce an unevenness of a surface of a body, a sacrificial layer is applied to the surface, a chemical-mechanical polishing of the sacrificial layer and material of said body is performed to reduce the unevenness of the surface, and a remainder of the sacrificial layer, if any, may be removed.

  • Patent number: 6303980
    Abstract: A fusible link in an integrated semiconductor circuit and a process for producing the fusible link contemplate the disposition of a fusible link, which is constructed with a cross-sectional constriction as a desired fusing point for its conductor track, in a void. A surface of the void and/or a bare conductor track can be covered with a protection layer, to prevent corrosion. The advantages of such a fusible link are a lower ignition energy and increased reliability. The fusible link may be used as a memory element of a PROM.

  • Patent number: 5777376
    Abstract: A pnp-type bipolar transistor includes a highly dop p-conducting emitter zone, a base zone and a buried n-conducting zone below the emitter zone. An additional p-conducting region is connected to the highly doped emitter zone and is disposed between the highly doped emitter zone and the buried zone. A collector zone includes a highly doped collector connection zone and a p-conducting region reaching from the collector connection zone to the buried zone.
