Outline of Final Research Achievements

In this present study, we have fabricated a novel nano-mist CVD apparatus with two channels and developed a software that could be controlled the composition ratio of the both mist of In2O3 and SnO2 thin films preparing solution, and also succeeded in preparing In-Sn-O system thin films controlled the composition of In and Sn.
Subsequently, In2O3 thin films of 120 nm thickness were deposited on the substrate along an original deposition time chart related to dynamic composition control. By this mixture method upon mist discharge, we succeeded in accumulating the 120-nm-thick In-Sn-O system thin film, with the composition gradually inclined from 0 to 12 at.% Sn, on this In2O3 thin film.
