  • Patent number: 7951625
    Abstract: In a semiconductor light emitting device, light is lost from a side surface of a substrate; therefore, if a substrate side surface occupies a large area, it decreases light extraction efficiency. The area of the substrate side surface may be reduced by reducing a thickness of the substrate. However, a thin substrate has low mechanical strength and is cracked by a stress during work process, and that decreases the yield. A light emitting layer is formed on a substrate. After fixed to a grinding board with wax, the substrate is ground to thin. A support substrate is then bonded to the substrate for reinforcement. The substrate is fixed to an electrode and others, with the support substrate bonded to the substrate. The support substrate is lastly removed.

  • Patent number: 7951657
    Abstract: Disclosed are embodiments of a method of forming, on an SOI wafer, a planar FET with embedded and faceted source/drain stressors. The method incorporates a directional ion implant process to create amorphous regions at the bottom surfaces of source/drain recesses in a single crystalline semiconductor layer of an SOI wafer. Then, an etch process selective to different crystalline planes over others and further selective to single crystalline semiconductor material over amorphous semiconductor material can be performed in order to selectively adjust the shape (i.e., the profile) of the recess sidewalls without increasing the depth of the recesses. Subsequently, an anneal process can be performed to re-crystallize the amorphous regions and an epitaxial deposition process can be used to fill the recesses with source/drain stressor material. Also disclosed are embodiments of a planar FET structure and a design structure for the planar FET.

  • Patent number: 7951660
    Abstract: A method for fabricating a metal-oxide-semiconductor device structure. The method includes introducing a dopant species concurrently into a semiconductor active layer that overlies an insulating layer and a gate electrode overlying the semiconductor active layer by ion implantation. The thickness of the semiconductor active layer, the thickness of the gate electrode, and the kinetic energy of the dopant species are chosen such that the projected range of the dopant species in the semiconductor active layer and insulating layer lies within the insulating layer and a projected range of the dopant species in the gate electrode lies within the gate electrode. As a result, the semiconductor active layer and the gate electrode may be doped simultaneously during a single ion implantation and without the necessity of an additional implant mask.

    Abstract: A semiconductor device is made by forming a smooth conductive layer over a substrate. A first insulating layer is formed over a first surface of the smooth conductive layer. A first conductive layer is formed over the first insulating layer. A second insulating layer is formed over the first insulating layer and first conductive layer. The substrate is removed. A second conductive layer is formed over a second surface of the smooth conductive layer opposite the first surface of the smooth conductive layer. A third insulating layer is formed over the second conductive layer. The second conductive layer, smooth conductive layer, first insulating layer, and first conductive layer constitute a MIM capacitor. A portion of the second conductive layer includes an inductor. The smooth conductive layer has a smooth surface to reduce particles and hill-locks which decreases ESR, increases Q factor, and increases ESD of the MIM capacitor.
