  • Patent number: 9680016
    Abstract: An embodiment of the invention reduces the external resistance of a transistor by utilizing a silicon germanium alloy for the source and drain regions and a nickel silicon germanium self-aligned silicide (i.e., salicide) layer to form the contact surface of the source and drain regions. The interface of the silicon germanium and the nickel silicon germanium silicide has a lower specific contact resistivity based on a decreased metal-semiconductor work function between the silicon germanium and the silicide and the increased carrier mobility in silicon germanium versus silicon. The silicon germanium may be doped to further tune its electrical properties. A reduction of the external resistance of a transistor equates to increased transistor performance both in switching speed and power consumption.

  • Publication number: 20170144155
    Abstract: Systems and methods for conducting designated reactions that include a fluidic network having a sample channel, a reaction chamber, and a reservoir. The sample channel is in flow communication with a sample port. The system also includes a rotary valve that has a flow channel and is configured to rotate between first and second valve positions. The flow channel fluidically couples the reaction chamber and the sample channel when the rotary valve is in the first valve position and fluidically couples the reservoir and the reaction chamber when the rotary valve is in the second valve position. A pump assembly induces a flow of a biological sample toward the reaction chamber when the rotary valve is in the first valve position and induces a flow of a reaction component from the reservoir toward the reaction chamber when the rotary valve is in the second valve position.

  • Patent number: 9627321
    Abstract: At least one conductive line in a dielectric layer over a substrate is recessed to form a channel. The channel is self-aligned to the conductive line. The channel can be formed by etching the conductive line to a predetermined depth using a chemistry comprising an inhibitor to provide uniformity of etching independent of a crystallographic orientation. A capping layer to prevent electromigration is deposited on the recessed conductive line in the channel. The channel is configured to contain the capping layer within the width of the conductive line.

  • Publication number: 20170011998
    Abstract: Techniques are disclosed that enable improved shorting margin between unlanded conductive interconnect features and neighboring conductive features. In some embodiments, an etch may be applied to an insulator layer having one or more conductive features therein, such that the insulator layer is recessed below the top of the conductive features and the edges of the conductive features are rounded or otherwise softened. A conformal etchstop layer may then be deposited over the conductive features and the insulator material. A second insulator layer may be deposited above the conformal etchstop layer, and an interconnect feature may pass through the second insulator layer and the conformal etchstop layer to connect with the rounded portion of one of the conductive features. In some embodiments, the interconnect feature is an unlanded via and the unlanded portion of the via may or may not penetrate through the conformal barrier layer.

  • Publication number: 20160356715
    Abstract: Biosensor including a device base having a sensor array of light sensors and a guide array of light guides. The light guides have input regions that are configured to receive excitation light and light emissions generated by biological or chemical substances. The light guides extend into the device base toward corresponding light sensors and have a filter material. The device base includes device circuitry electrically coupled to the light sensors and configured to transmit data signals. The biosensor also includes a shield layer having apertures that are positioned relative to the input regions of corresponding light guides such that the light emissions propagate through the apertures into the corresponding input regions. The shield layer extends between adjacent apertures and is configured to block the excitation light and the light emissions incident on the shield layer between the adjacent apertures.

  • Patent number: 9112029
    Abstract: Various embodiments of the invention relate to a CMOS device having (1) an NMOS channel of silicon material selectively deposited on a first area of a graded silicon germanium substrate such that the selectively deposited silicon material experiences a tensile strain caused by the lattice spacing of the silicon material being smaller than the lattice spacing of the graded silicon germanium substrate material at the first area, and (2) a PMOS channel of silicon germanium material selectively deposited on a second area of the substrate such that the selectively deposited silicon germanium material experiences a compressive strain caused by the lattice spacing of the selectively deposited silicon germanium material being larger than the lattice spacing of the graded silicon germanium substrate material at the second area.
