  • Patent number: 8008193
    Abstract: Provided is a manufacturing method for improving the reliability of a semiconductor device having a back electrode. After formation of semiconductor elements on the surface of a silicon substrate, the backside surface thereof, which is opposite to the element formation surface, is subjected to the following steps in a processing apparatus. After deposition of a first metal film over the backside surface of the silicon substrate in a first chamber, it is heat treated to form a metal silicide film. Then, a nickel film is deposited in a third chamber, followed by deposition of an antioxidant conductor film in a second chamber. Heat treatment for alloying the first metal film and the silicon substrate is performed at least prior to the deposition of the nickel film. The first chamber has therefore a mechanism for depositing the first metal film and a lamp heating mechanism.

  • Publication number: 20110195570
    Abstract: The described embodiments of methods of bottom-up metal deposition to fill interconnect and replacement gate structures enable gap-filling of fine features with high aspect ratios without voids and provide metal films with good film quality. In-situ pretreatment of metal film(s) deposited by gas cluster ion beam (GCIB) allows removal of surface impurities and surface oxide to improve adhesion between an underlying layer with the deposited metal film(s). Metal films deposited by photo-induced chemical vapor deposition (PI-CVD) using high energy of low-frequency light source(s) at relatively low temperature exhibit liquid-like nature, which allows the metal films to fill fine feature from bottom up. The post deposition annealing of metal film(s) deposited by PI-CVD densifies the metal film(s) and removes residual gaseous species from the metal film(s). For advanced manufacturing, such bottom-up metal deposition methods address the challenges of gap-filling of fine features with high aspect ratios.

  • Patent number: 7932585
    Abstract: At least one film composite is laminated on a surface of at least one electrical component. The film composite includes at least one electrically-conducting plastic film with at least one electrically conducting conductor. The electrically-conducting plastic film has a high-ohmic resistance. This method may be used in planar large-surface electrical contacting technology for the production of modules with power semiconductors, where an electrical contacting of the components is achieved by the plastic films. A low lateral electrical conductivity is achieved, such that an electrical charging of the plastic films required for the contacting technology is prevented on operation of the component or the module.

  • Publication number: 20110079814
    Abstract: A method for producing the LED substrate has steps of: p providing a conductive metallic board, forming multiple grooves in a top of the conductive metallic board; protecting the conductive metallic board from corrosion, forming an etched substrate with circuits and wires for plating on the conductive metallic board, electroless plating the etched substrate to form an electroless plated substrate, plating metal on the electroless plated substrate, and coating solder mask to obtain the LED substrate. Because LED chips are mounted on the surfaces of the metal layer without insulating adhesive below, heat from LED chips can be dissipated efficiently. The LED substrate of the present invention can be soldered directly onto a dissipation module to further enhance dissipation efficiency.

  • Publication number: 20110053369
    Abstract: Methods of forming a semiconductor include forming an insulation layer over a semiconductor substrate in which a first region and a second region are defined. A storage node contact (SNC) that passes through the insulation layer is formed and is electrically connected to the first region. A conductive layer that passes through the insulation layer is deposited and is electrically connected to the second region on the insulation layer and the SNC. A bit line is formed by removing an upper portion of the conductive layer, an upper portion of the insulation layer and an upper portion of the SNC until the SNC and the conductive layer are electrically separated from each other, wherein the bit line is a remaining part of the conductive layer.
