    摘要: The present invention provides a method for manufacturing a semiconductor device. In one embodiment of the present invention, without limitation, the method for manufacturing the semiconductor device includes forming a gate structure (120) over a substrate (110) and forming source/drain regions (190) in the substrate (110) proximate the gate structure (120). The method further includes forming fluorine containing regions (220) in the source/drain regions (190) employing a fluorine containing plasma using a power level of less than about 75 Watts, forming a metal layer (310) over the substrate (110) and fluorine containing regions (220), and reacting the metal layer (310) with the fluorine containing regions (220) to form metal silicide regions (410) in the source/drain regions (190).

    摘要: A method of forming an integrated circuit transistor (50). The method provides a first semiconductor region (52) and forms (110) a gate structure (54x) in a fixed position relative to the first semiconductor region. The gate structure has a first sidewall and a second sidewall (59x). The method also forms at least a first layer (58x, 60x) adjacent the first sidewall and the second sidewall. The method also forms (120) at least one recess (62x) in the first semiconductor region and extending laterally outward from the gate structure. Additional steps in the method are first, oxidizing (130) the at least one recess such that an oxidized material is formed therein, second, stripping (140) at least a portion of the oxidized material, and third, forming (160) a second semiconductor region (66x) in the at least one recess.

    摘要: Chemical mechanical polishing slurry with functionalized silica abrasive particles, the functionalization permits high pH slurry without rapid degradation of silica particles and also permits the modification of surface properties of abrasive particles to modify slurry behavior. One example of modified behavior would be to enhance selectivity by controlling particle interaction with different surfaces on the wafer.
