  • Publication number: 20100117237
    Abstract: A trench contact silicide is formed on an inner wall of a contact trench that reaches to a buried conductive layer in a semiconductor substrate to reduce parasitic resistance of a reachthrough structure. The trench contact silicide is formed at the bottom, on the sidewalls of the trench, and on a portion of the top surface of the semiconductor substrate. The trench is subsequently filled with a middle-of-line (MOL) dielectric. A contact via may be formed on the trench contact silicide. The trench contact silicide may be formed through a single silicidation reaction with a metal layer or through multiple silicidation reactions with multiple metal layers.

  • Patent number: 7138691
    Abstract: A semiconductor structure includes thin gate dielectrics that have been selectively nitrogen enriched. The amount of nitrogen introduced is sufficient to reduce or prevent gate leakage and dopant penetration, without appreciably degrading device performance. A lower concentration of nitrogen is introduced into pFET gate dielectrics than into nFET gate dielectrics. Nitridation may be accomplished selectively by various techniques, including rapid thermal nitridation (RTN), furnace nitridation, remote plasma nitridation (RPN), decoupled plasma nitridation (DPN), well implantation and/or polysilicon implantation.

  • Patent number: 7112481
    Abstract: A method of fabricating a complementary metal oxide semiconductor (CMOS) device, wherein the method comprises forming a first well region in a semiconductor substrate for accommodation of a first type semiconductor device; forming a second well region in the semiconductor substrate for accommodation of a second type semiconductor device; shielding the first type semiconductor device with a mask; depositing a first metal layer over the second type semiconductor device; performing a first salicide formation on the second type semiconductor device; removing the mask; depositing a second metal layer over the first and second type semiconductor devices; and performing a second salicide formation on the first type semiconductor device. The method requires only one pattern level and it eliminates pattern overlay as it also simplifies the processes to form different silicide material over different devices.

  • Patent number: 7045372
    Abstract: A method and structure that provides a battery within an integrated circuit for providing voltage to low-current electronic devices that exist within the integrated circuit. The method includes Front-End-Of-Line (FEOL) processing for generating a layer of electronic devices on a semiconductor wafer, followed by Back-End-Of-Line (BEOL) integration for wires connecting the electronic devices together to form completed electrical circuits of the integrated circuit. The BEOL integration includes forming a multilayered structure of wiring levels on the layer of electronic devices. Each wiring level includes conductive metallization (e.g., metal-plated vias, conductive wiring lines, etc.) embedded in insulative material. The battery is formed during BEOL integration within one or more wiring levels, and the conductive metallization conductively couples positive and negative terminals of the battery to the electronic devices.

  • Patent number: 6909157
    Abstract: Methods such as Remote Plasma Nitridation (RPN) are used to introduce nitrogen into a gate dielectric layer. However, these methods yield nitrided layers where the layers are not uniform, both in cross-sectional profile and in nitrogen profile. Subjecting the nitrided layer to an additional NO anneal process increases the uniformity of the nitrided layer.
