摘要:
A semiconductor device manufacturing method has forming element isolation trenches in a semiconductor substrate, forming a silicon compound film in insides of the element isolation trenches in order to embed the element isolation trenches, conducting a first oxidation processing at a first temperature to reform a surface of the silicon compound film to a volatile matter emission preventing layer which permits passage of an oxidizing agent and impurities and which does not permit passage of a volatile matter containing silicon atoms, and conducting a second oxidation processing at a second temperature which is higher than the first temperature to form a coated silicon oxide film inside the element isolation trenches.

A welding system has: a welding mechanism, a reception laser light source, a reception optical mechanism, an interferometer, a data recording/analysis mechanism and a data recording/analysis mechanism. The reception laser light source generates reception laser light so as to irradiate the object to be welded with the reception laser light for the purpose of detecting a reflected ultrasonic wave obtained as a result of reflection of a transmission ultrasonic wave. The reception optical mechanism transmits, during or after welding operation, the reception laser light generated from the reception laser light source to the surface of the object to be welded for irradiation while moving, together with the welding mechanism, relative to the object to be welded and collects laser light scattered/reflected at the surface of the object to be welded.
摘要:
Silicon nitride film is formed on a silicon wafer mounted in a boat in an LPCVD tool by feeding a silicon source (SiH2Cl2, SiCl4, Si2Cl6, etc.) from an injector and feeding a mixed gas of monomethylamine (CH3NH2) and ammonia (NH3) as the nitrogen source from an injector. This addition of monomethylamine to the source substances for film production makes it possible to provide an improved film quality and improved leakage characteristics even at low temperatures (450-600° C.).

摘要:
A method of manufacturing a silicon nitride film that forms a silicon nitride film on a surface of a substrate comprises sequentially repeating first through third steps. The first step includes feeding a first gas containing silicon and nitrogen to the surface of the substrate. The second step includes feeding a second gas containing nitrogen to the surface of the substrate. The third step includes feeding a third gas containing hydrogen to the surface of the substrate.
