Abstract
Abstract An interlayer insulating film of a semiconductor device is made of a material in which silicon atoms are main elements, and each of the silicon atoms has an oxygen bond and a carbon bond, and further at least some of the silicon atoms have a hydrogen bond. The interlayer insulating film is formed by chemical vapor deposition employing a mixed gas of hydrogen peroxide and a reactive gas having a gas molecular structure in which silicon atoms have a hydrogen bond and a carbon bond.
