摘要： A high-temperature high-pressure processing method for semiconductor wafers in which semiconductor wafers are charged into a pressure vessel to carry out processing under the gas atmosphere of high-temperature high-pressure, wherein the high-temperature high-pressure processing is carried out in the state that an anti-oxidizing body (an oxygen getter member) formed of a material having properties in which oxygen is apt to diffuse into interior is arranged within the pressure vessel whereby the anti-oxidizing body takes oxygen into the pressure vessel, thus preventing oxygen within the pressure vessel from being reduced to oxidize the surfaces of the semiconductor wafers in the high-temperature high-pressure processing.

摘要： A wiring film, which can be formed into wiring for ULSI semiconductor circuits, is formed by first forming holes in an insulating film on a substrate; then depositing a metallic material of copper, copper alloy, silver or silver alloy into the holes under an atmosphere including hydrogen; and finally annealing the deposited metallic material. The metallic material can be deposited by a sputtering process in which the atmosphere includes an inert gas in addition to the hydrogen. Hydrogen doped in the metallic material during the sputtering process promotes diffusion of atoms in the metallic material. The diffusion eliminates voids in the deposited metallic material.

摘要： An apparatus treating substrates in a high-temperature and high-pressure atmosphere, the substrates being treated in a batch that includes one lot of the substrates treated as a unit. A supporting jig is provided with means to support a plurality of the substrates in a shelved arrangement, the supporting jig and substrates being configured to enter and exit from a treating chamber within a pressure vessel as a single unit. The supporting jig is surrounded by a casing. In order to cope with the difficulty of oxidization of the substrates, an oxygen getter is disposed in either the supporting jig or in the casing. The pressure vessel includes an opening whereby a reducing gas can be introduced into the treating chamber. Further, the pressure vessel and a stocking portion of the substrates are installed within a housing such that contamination is further reduced and control is made easier.

摘要： This invention provides a method of forming a metal wiring film excellent in EM resistance and low electric resistance. In a method of forming a wiring structure by filming and covering the surface of the insulating film of a substrate to be treated having a hole or groove formed thereon with a metallic material such as copper, aluminum, silver or the like, thereby filling the hole or groove inner part with the metallic material to form a wiring structure, the substrate to be treated is exposed to a high temperature under a high-pressure gas atmosphere after the continuous filming and covering with the metallic material along the inner surface profile of the hole or groove, whereby the surface diffusion phenomenon of the metallic material is promoted to reform the metal film into a film structure as the surface area of the metal film is minimized.
