Webphysical thickness [2]. Many candidates of possible high-k gate dielectrics have been suggested to replace SiO2 and they include nitrided SiO2, Hf-based oxides, and Zr-based oxides. Hf-based oxides have been recently highlighted as the most suitable dielectric materials because of their comprehensive performance. One of the key issues concerning WebWe report the fabrication of bottom gate a-IGZO TFTs based on HfO2 stacked dielectrics with decent electrical characteristics and bias stability. The microscopic, electrical, and …

WebJun 12, 2015 · To overcome this dilemma, high-κ materials that exhibit a larger permittivity and band gap are introduced as gate dielectrics to enhance both the capacitance and block leakage simultaneously.... Webtween the high-k dielectric and the Si substrate has been one of the major issues in the high-k gate dielectrics. It has also been reported that the degraded mobil-ity of HfO 2 MOSFET could be improved by high temperature forming gas and deuterium gas annealing [5, 6]. In other word, high temperature forming gas or WebAnother option that has been evaluated is the use of high-K dielectric as the trapping layer in the SONOS stack. Here the choice of the material and processing is directed toward … dr zoran čeović
