  • Patent number: 8399995
    Abstract: A semiconductor device includes a chip. The chip includes a single circuit element formed in a semiconductor substrate, a first metal layer on a first face of the semiconductor substrate, and a second metal layer on a second face of the semiconductor substrate opposite the first face. The first metal layer and the second metal layer are configured for accessing the single circuit element. A smaller of a first width of the first face of the semiconductor substrate and a second width of the first face of the semiconductor substrate perpendicular to the first width is less than or equal to a distance between an exposed face of the first metal layer parallel to the first face of the semiconductor substrate and an exposed face of the second metal layer parallel to the second face of the semiconductor substrate.

  • Patent number: 8156643
    Abstract: A method of electrically interconnecting a semiconductor chip to another electronic device including providing a carrier including contact pins and a chip attached to the carrier, the chip having a copper contact pad that faces away from the carrier, extending a copper electrical connector between the contact pins and the contact pad, and diffusion soldering the copper electrical connector to the active area with a solder material including tin to form a solder connection including a contiguous bronze coating disposed between and in direct contact with both the copper electrical connector and the contact pad.

  • Patent number: 8097918
    Abstract: A semiconductor arrangement including a load transistor and a sense transistor that are integrated in a semiconductor body. One embodiment provides a number of transistor cells integrated in the semiconductor body, each transistor cell including a first active transistor region. A number of first contact electrodes, each of the contact electrodes contacting the first active transistor regions through contact plugs. A second contact electrode contacts a first group of the first contact electrodes, but not contacting a second group of the first contact electrodes. The transistor cells being contacted by first contact electrodes of the first group form a load transistor, with the second electrode forming a load terminal of the load transistor. The transistor cells being contacted by first contact electrodes of the second group form a sense transistor.
