摘要： Oxide growth of a gate dielectric layer that occurs between processes used in the fabrication of a gate dielectric structure can be reduced. The reduction in oxide growth can be achieved by maintaining the gate dielectric layer in an ambient effective to mitigate oxide growth of the gate dielectric layer between at least two sequential process steps used in the fabrication the gate dielectric structure. Maintaining the gate dielectric layer in an ambient effective to mitigate oxide growth also improves the uniformity of nitrogen implanted in the gate dielectric.

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.
