Abstract: The present invention provides a method for forming a chemical vapor deposition film which is suitable for an interlevel insulator between Al and Al or an interlevel insulator between Al and a gate, and provides an improved chemical vapor deposition film suitable for mass production. An organic siloxane or alkoxysilane and an alkoxy compound of germanium are mixed in a vapor phase, and reacted with oxygen or ozone to thereby form a thin glass film composed of a two-component system of silicon oxide and germanium oxide on a substrate.

Abstract: An apparatus and method for manufacturing a semiconductor device capable of forming a single layer film or a multilayer film of improved quality by continuously processing without exposure of the wafer to the ambient air. The apparatus includes a film forming section having a gas dispersion unit for supplying reaction gas, a processing section for processing the formed film and a wafer holder for holding a wafer facing the gas dispersion unit or the processing section. The wafer holder moves the wafer between the film forming section and the processing section while heating the wafer by a heating element contained therein.
