    摘要: A silicon nitrate layer (110) is formed over a transistor gate (40) and source and drain regions (70). The as-formed silicon nitride layer (110) comprises a first tensile stress and a high hydrogen concentration. The as-formed silicon nitride layer (110) is thermally annealed converting the first tensile stress into a second tensile stress that is larger than the first tensile stress. Following the thermal anneal, the hydrogen concentration in the silicon nitride layer (110) is greater than 12 atomic percent.

    摘要: A method is disclosed for implanting and activating antimony as a dopant in a semiconductor substrate. A method is also disclosed for implanting and activating antimony to form a source/drain extension region in the formation of a transistor, in such a manner as to achieve high activation and avoid deactivation via subsequent exposure to high temperatures. This technique facilitates the formation of very thin source/drain regions that exhibit reduced sheet resistance while also suppressing short channel effects. Enhancements to these techniques are also suggested for more precise implantation of antimony to create a shallower source/drain extension, and to ensure formation of the source/drain extension region to underlap the gate. Also disclosed are transistors and other semiconductor components that include doped regions comprising activated antimony, such as those formed according to the disclosed methods.

    摘要: The present application is directed to a method for forming a metal silicide layer. The method comprises providing a substrate comprising silicon and depositing a metal layer on the substrate. The metal layer is annealed within a first temperature range and for a first dwell time of about 10 milliseconds or less to react at least a portion of the metal with the silicon to form a silicide. An unreacted portion of the metal is removed from the substrate. The silicide is annealed within a second temperature range for a second dwell time of about 10 milliseconds or less.
