    摘要: The present invention relates to a composite sputtering target comprising a plurality of bonded metal pieces. The composite sputtering target further comprises a bonded region between the metal pieces. The bonded region may comprise an inter-metallic region upon bonding. The composite sputter target of the present invention may be used in conjunction with an apparatus for sputtering alloy films on substrates.

    摘要: Passivation coatings and gettering agents may be used in an Extreme Ultraviolet (EUV) source which uses tin (Sn) vapor as a plasma “fuel” to prevent contamination and corresponding loss of reflectivity due to tin contamination. The passivation coating may be a material to which tin does not adhere, and may be placed on reflective surfaces in the source chamber. The gettering agent may be a material that reacts strongly with tin, and may be placed outside of the collector mirrors and/or on non-reflective surfaces. A passivation coating may also be provided on the insulator between the anode and cathode of the source electrodes to prevent shorting due to tin coating the insulator surface.

    摘要: A high-K thin film patterning solution is disclosed to address structural and process limitations of conventional patterning techniques. Subsequent to formation of gate structures adjacent a high-K dielectric layer, a portion of the high-K dielectric layer material is reduced, preferably via exposure to hydrogen gas, to form a reduced portion of the high-K dielectric layer. The reduced portion may be selectively removed utilizing wet etch chemistries to leave behind a trench of desirable geometric properties.
