  • Patent number: 7935611
    Abstract: A silicon layer having a conductivity type opposite to that of a bulk is provided on the surface of a silicon substrate and hydrogen ions are implanted to a predetermined depth into the surface region of the silicon substrate through the silicon layer to form a hydrogen ion-implanted layer. Then, an n-type germanium-based crystal layer whose conductivity type is opposite to that of the silicon layer and a p-type germanium-based crystal layer whose conductivity type is opposite to that of the germanium-based crystal layer are successively vapor-phase grown to provide a germanium-based crystal. The surface of the germanium-based crystal layer and the surface of the supporting substrate are bonded together. In this state, impact is applied externally to separate a silicon crystal from the silicon substrate along the hydrogen ion-implanted layer, thereby transferring a laminated structure composed of the germanium-based crystal and the silicon crystal onto the supporting substrate.

  • Patent number: 7935559
    Abstract: This method for producing a non-planar microelectronic component, especially a concave component, involves superposing a layer that contains an active flexible circuit above a cavity shaped according to the desired profile of said component, said cavity being formed in substrate; and applying a pressure difference either side of said layer thereby causing slumping of the flexible circuit into the cavity therefore causing the circuit to assume the shape of the cavity. Superposition of the flexible circuit and the cavity is realized by filling the cavity with a material capable of being selectively removed relative to the substrate and the flexible circuit; then fitting or forming the flexible circuit on the cavity thus filled; then forming at least one feedthrough to access the filled cavity; and by selectively etching the material that fills the cavity via at least one feedthrough in order to remove said material.

  • Patent number: 7915114
    Abstract: Method of fabricating a thin-film transistor (TFT) in which a gate metal is deposited onto a substrate in order to form the gate of the thin-film transistor. The substrate may be an insulative substrate or a color filter. In a first method, the gate metal is subjected to an H2 plasma. After subjecting the gate metal to an H2 plasma, the gate insulating film is deposited onto the gate. In a second method, first and second layers of gate insulating film are respectively deposited on the gate at a first and second deposition rates. One layer is deposited under H2 or argon dilution conditions and has improved insulating conditions while the other layer serves to lower the overall compressive stress of the dual layer gate insulator. In a third method, an n+ silicon film is formed on a substrate by maintaining a flow of silane, phosphine and hydrogen gas into a processing chamber at substrate temperatures of about 300° C. or less.
