Effects of annealing gas on electrical properties of La2O3 gate dielectrics

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Solution-processed lanthanum oxide(La2O3) films were formed on the Si substrates under N2 and O2 ambience annealing conditions. Compared to N2 conditions, flat-band voltage shifted to positive gate bias direction and leakage current was less for O2 annealed devices resulted from the reduction of the oxygen-related trap sites in the film.
