Abstract

Reduction of the gate leakage current in nMOS high-k devices is demonstrated by an engineered two-step deposited Hf-based high-k dielectric film. The electrical characteristics and reliability of the devices fabricated using the proposed two-step and conventional one-step high-k gate stacks are shown to be comparable. The lower leakage current is attributed to the misalignment of the grain boundaries in the multi-layer high-k dielectrics.
