    摘要: An object of the invention is to provide a semiconductor device having improved performance. A method of manufacturing a semiconductor device includes: forming a trench and then forming a first insulating film made of a silicon oxide film through CVD using a gas containing an O 3 gas and a TEOS gas to cover the side surface of the trench with the insulating film; forming a second insulating film made of a silicon oxide film through PECVD to cover the side surface of the trench with the second insulating film via the first insulating film; and forming a third insulating film made of a silicon oxide film through CVD using a gas containing an O 3 gas and a TEOS gas to close the trench with the third insulating film while leaving a space in the trench.
