  • Patent number: 8070443
    Abstract: A turbine rotor blade with a leading edge region cooled by a series of impingement cooling cavities that repeats from near the platform to the blade tip to provide impingement cooling for the leading edge without a loss of cooling air flow volume. A cooling supply cavity delivers cooling air to a series of impingement cavities located on the pressure side, the leading edge and the suction side of the airfoil in a series flow. The spent cooling air from the series then flows up into the next series of impingement cavities to provide impingement cooling to the next section of the leading edge. The cooling air flows through multiple series of impingement cooling cavities until the blade tip, which then discharges the spent impingement cooling air through tip cooling holes.

  • Patent number: 8043959
    Abstract: A method of forming a low-k dielectric layer or film includes forming a porous low-k dielectric layer or film over a wafer or substrate. Active bonding is introduced into the porous low-k dielectric layer or film to improve damage resistance and chemical integrity of the layer or film, to retain the low dielectric constant of the layer and film after subsequent processing. Introduction of the active bonding may be accomplished by introducing OH and/or H radicals into pores of the porous low-k dielectric layer or film to generate, in the case of a Si based low-k dielectric layer or film, Si—OH and/or Si—H active bonds. After further processing of the low-k dielectric film, the active bonding is removed from the low-k dielectric layer or film.

  • Patent number: 8043921
    Abstract: A method of removing silicon nitride over a semiconductor surface for forming shallow junctions. Sidewall spacers are formed along sidewalls of a gate stack that together define lightly doped drain (LDD) regions or source/drain (S/D) regions. At least one of the sidewall spacers, LDD regions and S/D regions include an exposed silicon nitride layer. The LDD or S/D regions include a protective dielectric layer formed directly on the semiconductor surface. Ion implanting implants the LDD regions or S/D regions using the sidewall spacers as implant masks. The exposed silicon nitride layer is selectively removed, wherein the protective dielectric layer when the sidewall spacers include the exposed silicon nitride layer, or a replacement protective dielectric layer formed directly on the semiconductor surface after ion implanting when the LDD or S/D regions include the exposed silicon nitride layer, protects the LDD or S/D regions from dopant loss due to etching during selectively removing.
