摘要:
Process for producing silicon oxide containing thin films on a growth substrate by the ALCVD method. In the process, a vaporizable silicon compound is bonded to the growth substrate, and the bonded silicon compound is converted to silicon dioxide. The invention comprises using a silicon compound which contains at least one organic ligand and the bonded silicon compound is converted to silicon dioxide by contacting it with a vaporized, reactive oxygen source, in particular with ozone. The present invention provides a controlled process for growing controlling thin films containing SiO2, with sufficiently short reaction times.

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.
