The source-drain electrodes are composed of oxygen-containing layers and thin films of pure copper or a copper alloy. The oxygen-containing layer contains oxygen such that part or all of oxygen combines with silicon in the semiconductor layer. And, the thin films of pure copper or a copper alloy connect with the semiconductor layer of the thin film transistor through the oxygen-containing layers.

  • Patent number: 7859011
    Abstract: A semiconductor device may comprise a partially-depleted SOI MOSFET having a floating body region disposed between a source and drain. The floating body region may be driven to receive injected carriers for adjusting its potential during operation of the MOSFET. In a particular case, the MOSFET may comprise another region of semiconductor material in contiguous relationship with a drain/source region of the MOSFET and on a side thereof opposite to the body region. This additional region may be formed with a conductivity of type opposite the drain/source, and may establish an effective bipolar device per the body, the drain/source and the additional region. The geometries and doping thereof may be designed to establish a transport gain of magnitude sufficient to assist the injection of carriers into the floating body region, yet small enough to guard against inter-latching with the MOSFET.

  • Patent number: 7858472
    Abstract: An integrated non-volatile memory circuit is formed by first growing a thin dielectric layer on a semiconductor substrate surface, followed by depositing a layer of conductive material such as doped polysilicon on this dielectric layer, the conductive material then being separated into rows and columns of individual floating gates. Cell source and drain diffusions in the substrate are continuously elongated across the rows. Field dielectric deposited between the rows of floating gates provides electrical isolation between the rows. Shallow trenches may be included between rows without interrupting the conductivity of the diffusions along their lengths. A deep dielectric filled trench is formed in the substrate between the array and peripheral circuits as electrical isolation. Various techniques are included that increase the field coupling area between the floating gates and a control gate.
