Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 下地材料に対して損傷を与えることなく、弗 素を含む酸化硅素薄膜からなる絶縁膜を作成する。 【構成】 第一の発明では、酸素のプラズマに弗素を含 む硅素化合物ガスと水素を含む硅素化合物ガスとを混合 させて導入し、気相成長を利用して基板40の表面に弗 素を含む酸化硅素薄膜を作成する。弗素を含む硅素化合 物と水素を含む硅素化合物との合計ガス流量に対する弗 素を含む硅素化合物ガスの流量は、50%から1%の範 囲である。第二の発明では、酸素と水素のプラズマに弗 素を含む硅素化合物ガスを導入し、同様に弗素を含む酸 化硅素薄膜を作成する。弗素を含む硅素化合物のガス流 量に対する水素ガスの流量は、200%から400%の 範囲である。 (57) [Abstract] [Purpose] To create an insulating film made of a silicon oxide thin film containing fluorine without damaging the underlying material. According to the first aspect of the present invention, oxygen plasma is mixed with a fluorine-containing silicon compound gas and a hydrogen-containing silicon compound gas and is introduced, and vapor deposition is used to oxidize fluorine on the surface of the substrate 40. Create a silicon thin film. The flow rate of the fluorine-containing silicon compound gas with respect to the total gas flow rate of the fluorine-containing silicon compound and the hydrogen-containing silicon compound is in the range of 50% to 1%. In the second invention, a fluorine-containing silicon compound gas is introduced into oxygen and hydrogen plasma to similarly form a fluorine-containing silicon oxide thin film. The flow rate of hydrogen gas with respect to the gas flow rate of a silicon compound containing fluorine is in the range of 200% to 400%.
