Abstract:

A planar, double-gate transistor structure comprising upper and lower gate stacks that each comprises a single-phase high-K dielectric gate dielectric is disclosed. The transistor structure is particularly suitable for fully-depleted silicon-on-insulator electronics having gate-lengths less than 65 nm.

Abstract(Chinese):
