Abstract
A method of fabricating a MOS transistor by millisecond annealing. A semiconductor substrate with a gate stack comprising a gate electrode overlying a gate dielectric layer on a top surface of a semiconductor substrate is provided. At least one implanting process is performed to form two doped regions on opposite sides of the gate electrode. Millisecond annealing activates dopants in the doped regions. The millisecond anneal includes rapid heating and rapid cooling within 1 to 50 milliseconds.
