摘要: A turbine motor for a pneumatic tool, comprising a casing, a rotor and an axis. Compressed air enters the casing through an inlet and is directed towards blades of the rotor in a radial direction, so that torque is exerted on the axis. The blades of the rotors are to a large part hit by compressed air, each for an extended time, so that high effectivity and good efficiency result, allowing for operation at high speed and under high load.

摘要: A recuperated gas turbine engine. The gas turbine engine includes a heat exchanger, and gas turbine (including compressor, can-type combustor and turbine). The heat exchanger includes a compressed air passageway and a turbine exhaust gas passageway adjacent to each other within the casing which extend spirally throughout the heat exchanger and towards an inner cylindrical chamber in which the combustor is positioned approximately to the center of the casing. Improved engine fuel efficiency is achieved by preheating the compressed air before it reaches the combustor with the higher-temperature exhaust gas. A can-type combustor is used for alleviating heat-dissipation issues to improve efficiency of the combustion. A concentric back-to-back rotor arrangement significantly shortens the length of a conventional engine turbine rotor which improves on the operational stability of a gas turbine engine.

摘要: MOSFET transistors having localized stressors for improving carrier mobility are provided. Embodiments of the invention comprise a gate electrode formed over a substrate, a carrier channel region in the substrate under the gate electrode, and source/drain regions on either side of the carrier channel region. The source/drain regions include an embedded stressor having a lattice constant different from the substrate. In a preferred embodiment, the substrate is silicon and the embedded stressor is SiGe. Implanting a portion of the source/drain regions with Ge forms the embedded stressor. Implanting carbon into the source/drain regions and annealing the substrate after implanting the carbon suppresses dislocation formation, thereby improving device performance.

摘要: A MOS transistor having a highly stressed channel region and a method for forming the same are provided. The method includes forming a first semiconductor plate over a semiconductor substrate, forming a second semiconductor plate on the first semiconductor plate wherein the first semiconductor plate has a substantially greater lattice constant than the second semiconductor plate, and forming a gate stack over the first and the second semiconductor plates. The first and the second semiconductor plates include extensions extending substantially beyond side edges of the gate stack. The method further includes forming a silicon-containing layer on the semiconductor substrate, preferably spaced apart from the first and the second semiconductor plates, forming a spacer, a LDD region and a source/drain region, and forming a silicide region and a contact etch stop layer. A high stress is developed in the channel region. Current crowding effects are reduced due to the raised silicide region.
