  • Patent number: 7520938
    Abstract: An object is subjected to high-pressure processing by bringing at least a high-pressure fluid into contact with the object under pressure in a high-pressure processing chamber, and then the high-pressure processing chamber is depressurized while the temperature in the chamber is controlled to be maintained above a temperature achieved by an adiabatic expansion, the adiabatic expansion starting from the pressure and temperature at the end of the high-pressure processing step. To control in such a way, the temperature in the high-pressure processing chamber is controlled so as to suppress or recover a temperature descent caused by an adiabatic expansion during the depressurizing step. This solves a problem in which the temperature is decreased to the vapor-liquid phase coexistence region or a region in which a solid is deposited.

  • Publication number: 20040031441
    Abstract: A processing fluid is not only supplied toward a surface side of a substrate (W) from supply nozzles (13, 13), but also flow directions (R1, R1) of the processing fluid supplied from the respective supply nozzles 13 deviate from each other within the surface of the substrate (W). Therefore, a whirling flow (TF) of the processing fluid is formed over the surface of the substrate (W) and the processing fluid comes into contact with the surface of the substrate (W), thereby performing a predetermined surface treatment (e.g. cleaning, first rinsing, second rinsing and drying).

  • Patent number: 6491518
    Abstract: 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.

  • Patent number: 6299739
    Abstract: 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.
