An epitaxy hard mask is formed over the gate structure on the field oxide so that the epitaxy hard mask overlaps the semiconductor material in PMOS source/drain region. SiGe semiconductor material is epitaxially formed in the source/drain regions, so that that a top edge of the SiGe semiconductor material at the field oxide does not extend more than one third of a depth of the SiGe in the source/drain region abutting the field oxide. Dielectric spacers on lateral surfaces of the gate structure on the field oxide extend onto the SiGe; at least one third of the SiGe is exposed. Metal silicide covers at least one third of a top surface of the SiGe. A contact has at least half of a bottom of the contact directly contacts the metal silicide on the SiGe.

  • Patent number: 9245975
    Abstract: A metal-oxide-semiconductor transistor (MOS) and method of fabricating the same, in which the effective channel length is increased relative to the width of the gate electrode. A dummy gate electrode overlying dummy gate dielectric material is formed at the surface of the structure, with self-aligned source/drain regions, and dielectric spacers on the sidewalls of the dummy gate structure. The dummy gate dielectric underlies the sidewall spacers. Following removal of the dummy gate electrode and the underlying dummy gate dielectric material, including from under the spacers, a silicon etch is performed to form a recess in the underlying substrate. This etch is self-limiting on the undercut sides, due to the crystal orientation, relative to the etch of the bottom of the recess. The gate dielectric and gate electrode material are then deposited into the remaining void, for example to form a high-k metal gate MOS transistor.

  • Patent number: 9240404
    Abstract: An embedded resistor structure in an integrated circuit that can be formed in a replacement gate high-k metal gate metal-oxide-semiconductor (MOS) technology process flow. The structure is formed by etching a trench into the substrate, either by removing a shallow trench isolation structure or by silicon etch at the desired location. Deposition of the dummy gate polysilicon layer fills the trench with polysilicon; the resistor polysilicon portion is protected from dummy gate polysilicon removal by a hard mask layer. The resistor polysilicon can be doped during source/drain implant, and can have its contact locations silicide-clad without degrading the metal gate electrode.

  • Patent number: 9236308
    Abstract: Methods of fabricating fin structures having exposed upper fin portions with a uniform exposure height are disclosed herein. The fabrication methods include providing a substrate with plurality of fins and a dielectric material disposed between and over the plurality of fins, planarizing the dielectric material and the plurality of fins, and uniformly recessing the dielectric material to a pre-selected depth below upper surfaces of the plurality of fins to expose upper fin portions. The exposed upper fin portions, as a result of uniformly recessing the dielectric material, have a uniform exposure height above the recessed dielectric material. A protective film may be provided over the recessed dielectric material and exposed upper fin portions to preserve the uniform exposure height of the upper fin portions. The uniform exposure height of the exposed upper fin portions facilitates subsequent formation of one or more circuit structures above the substrate.

  • Publication number: 20160005380
    Abstract: A method of driving a display panel includes steps of generating a plurality of load signals, of which at least one load signal has a different timing from the rest of the load signals, generating data voltages synchronized to low periods of the load signals and outputting the data voltages to data lines. Accordingly, the data voltages synchronized to each of the load signals can be outputted to each of the data lines. A color coordinate problem occurring when applying a RGBW type may be solved by setting a charging time of a white sub-pixel different from the rest of the sub-pixels. Thus, display quality of a display apparatus including the display panel may be improved.

  • Patent number: 9232454
    Abstract: A method of offloading data is provided by a UE. The UE receives data from a macro cell base station over an MC-RB while an E-RAB between the macro cell base station and a gateway is established. The UE receives a first connection reconfiguration message from the macro cell base station after the E-RAB between a small cell base station and the gateway is established, and establishes an SC-RB according to the first connection reconfiguration message. Next, the UE receives a second connection reconfiguration message from the macro cell base station after a path between the macro cell base station and the gateway is switched to a path between the small cell base station and the gateway, and data for the MC-RB are exhausted on the macro cell base station. Then, the UE releases the MC-RB and switches to the SC-RB.

  • Publication number: 20150377599
    Abstract: The present invention describes an electronic fuze operable to complement a mechanical point impact fuze. The electronic fuze includes a voltage generator circuit, micro-controller, a piezo-electric sensor, a firing circuit and a safety lockout circuit. When a projectile strikes a target at an optimum angle, the mechanical point impact fuze is activated; when the strike angle is oblique, the mechanical point impact fuze may be ineffective but the piezo-electric sensor is operable to trigger the firing circuit. The safety lockout circuit ensures the firing circuit is operative only after a predetermined delay time when an n-channel FET is turned OFF. The micro-controller also generates a TIME-OUT signal, which provides for self-destruction of a projectile that has failed to explode.
