High-performance poly-silicon TFTs using HfO/sub 2/ gate dielectric

Abstract

High-performance low-temperature poly-Si thin-film transistors (TFTs) using high-/spl kappa/ (HfO/sub 2/) gate dielectric is demonstrated for the first time. Because of the high gate capacitance density and thin equivalent-oxide thickness contributed by the high-/spl kappa/ gate dielectric, excellent device performance can be achieved including high driving… (More)
