Abstract:
A method of manufacturing a semiconductor device, comprising the steps of:supplying a silane gas and H.sub.2 O.sub.2 in a first chamber in which a semiconductor substrate having a first insulating film formed thereon is placed to cause the silane gas and H.sub.2 O.sub.2 to react to each other in a vacuum having a first pressure to form a reflow SiO.sub.2 film having a thickness of 0.4 .mu.m to 1.4 .mu.m at an unpatterned area on said semiconductor substrate; andreducing the pressure of the vacuum in said chamber to a second pressure for a period of time to remove a stepped amount of water contained in the reflow SiO.sub.2 film.
