CARRIER MOBILITY IN SURFACE-CHANNEL TRANSISTORS, APPARATUS MADE THEREWITH, AND SYSTEM CONTAINING SAME
摘要:
A surface channel transistor is provided in a semiconductive device. The surface channel transistor is either a PMOS or an NMOS device. Epitaxial layers are disposed above the surface channel transistor to cause an increased bandgap phenomenon nearer the surface of the device. A process of forming the surface channel transistor includes grading the epitaxial layers.
