  • Patent number: 8828804
    Abstract: An electronic device and fabrication of an electronic device. One embodiment provides applying a paste including electrically conductive particles to a surface of a semiconductor wafer. The semiconductor wafer is singulated with the electrically conductive particles for obtaining a plurality of semiconductor chips. At least one of the plurality of semiconductor chips is placed over a carrier with the electrically conductive particles facing the carrier. The electrically conductive particles are heated until the at least one semiconductor chip adheres to the carrier.

  • Publication number: 20110309450
    Abstract: A semiconductor structure includes a first PMOS transistor element having a gate region with a first gate metal associated with a PMOS work function and a first NMOS transistor element having a gate region with a second metal associated with a NMOS work function. The first PMOS transistor element and the first NMOS transistor element form a first CMOS device. The semiconductor structure also includes a second PMOS transistor that is formed in part by concurrent deposition with the first NMOS transistor element of the second metal associated with a NMOS work function to form a second CMOS device with different operating characteristics than the first CMOS device.

  • Patent number: 7176075
    Abstract: The present invention is a novel field effect transistor having a channel region formed from a narrow bandgap semiconductor film formed on an insulating substrate. A gate dielectric layer is formed on the narrow bandgap semiconductor film. A gate electrode is then formed on the gate dielectric. A pair of source/drain regions formed from a wide bandgap semiconductor film or a metal is formed on opposite sides of the gate electrode and adjacent to the low bandgap semiconductor film.

  • Patent number: RE44657
    Abstract: A circuit with a large load driving capability, which is structured by single polarity TFTs, is provided. With a capacitor (154) formed between a gate electrode and an output electrode of a TFT (152), the electric potential of the gate electrode of the TFT (152) is increased by a boot strap and normal output with respect to an input signal is obtained without amplitude attenuation of an output signal due to the TFT threshold value. In addition, a capacitor (155) formed between a gate electrode and an output electrode of a TFT (153) compensates for increasing the electric potential of the gate electrode of the TFT (152), and a larger load driving capability is obtained.
