摘要:
According to the present invention, there are provided a manufacturing method of a semiconductor device, characterized in that, after a surface of a substrate is reformed by performing high frequency plasma irradiation processing in a state that the substrate is heated, organic silane and ozone are mixed with each other, and a silicon oxide film is formed on the substrate under normal pressure or reduced pressure and also a manufacturing method of a semiconductor device, characterized in that, after a surface of a substrate is reformed by performing high frequency plasma irradiation processing in a state that the substrate is heated, organic silane, gas containing impurities such as phosphorus or boron and ozone are mixed, and a PSG film, a BSG film, a BPSG film and the like are formed on the substrate under normal pressure or reduced pressure.
摘要:
The insulating film formed by CVD while heating is irradiated with ultraviolet rays. The process may be repeated. The apparatus therefore is also described.
摘要:
In a process for forming a CVD film, a polysiloxane compound having at least two silicon-oxygen bonds is reacted with ozone to form an SiO₂ film. If desired, the reaction may be effected in the presence of a gas containing an impurity mixed with the polysiloxane compound and ozone to form a PSG, BSG or BPSG film. In a semiconductor device, the SiO₂ film, or the PSG, BSG or BPSG film is used as a planarizing film, an interlayer insulating film, or a cover insulating film.

摘要:
In a process for producing a semiconductor device, deposition of a CVD-SiO₂ film (32) at a given first O₃ concentration according to a TEOS-O₃ reaction is followed by further deposition of a CVD-SiO₂ film (34) at a second O₃ concentration higher than the first O₃ concentration according to the TEOS-O₃ reaction to form a CVD-SiO₂ film having a predetermined thickness and a surface little uneven.
