Abstract
PURPOSE:To obtain a highly reliable gate insulation film of silicon oxide by positive column system plasma CVD using hydrocarbon containing organic silane having ethoxy group, oxygen, and chlorine as a material CONSTITUTION:A silicon oxide 202 is deposited on a substrate 201 and an insular silicon region 203 is formed theron Another silicon oxide 204 is deposited, as a gate dielectric film, over the insular region 203 by positive column plasma CDV using hydrocarbon, ie, trichloroethylene, containing an organic silane, ie, tetraethoxy silane, oxygen and chlorine as amaterial Subsequently, a gate electrode 205, impurity regions 206, 207, and a channel region 208 are formed Furthermore, contact holes 210, 211 and electrodes 212, 213 are formed to complete a TFT This method allows formation of highly reliable gate insulation film, ie, silicon oxide 204

Method of Manufacturing a Semiconductor Device

TL;DR: In this article, the amorphous silicon film is formed using silane gas diluted with hydrogen and crystallization is attained in the crystallization process even with the continuous formation of the base film through the polysilicon film in the single film forming chamber.
