Patent number: 5198392Abstract: In a method of forming an insulating film, a silicon dioxide film is formed on a silicon substrate by performing heat treatment in an oxidizing gas atmosphere which does not contain nitrogen, and then the silicon dioxide film is oxynitrided by performing heat treatment in an nitrous oxide atmosphere. Prior to the formation of the silicon dioxide film, the silicon substrate is cleaned by heating it in a reducing gas atmosphere, and then heating it in a reactive gas atmosphere.Type: GrantFiled: June 21, 1991Date of Patent: March 30, 1993Assignee: Oki Electric Industry Co., Ltd.Inventors: Hisashi Fukuda, Tomiyuki Arajawa

Patent number: 5009926Abstract: In a method of forming an insulating film on a substrate wherein a substrate is cleaned by heating it in an atmosphere of a reducing gas, and heating it in an oxidizing gas, and then growing an insulating film by heating the substrate in an atmosphere of a gas used to grow the film in the same reaction chamber, the insulating film is grown in stages and an insulating film grown in each stage is crystallized by heat treatment with a temperature higher than the heat treatment for the film growth. This can be accomplished by interposing a heat treatment with the higher temperature between successive film growth stages, or by using a higher temperature for the film growth for each stage with a temperature higher than that for the film growth in the preceding stage.Type: GrantFiled: May 11, 1990Date of Patent: April 23, 1991Assignee: Oki Electric Industry Co., Ltd.Inventor: Hisashi Fukuda
