Patent number: 7520938Abstract: 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.Type: GrantFiled: August 11, 2004Date of Patent: April 21, 2009Assignee: Kobe Steel, Ltd.Inventors: Yoshihiko Sakashita, Takahiko Ishii, Masahiro Yamagata, Tetsuya Yoshikawa

Publication number: 20040031441Abstract: 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).Type: ApplicationFiled: March 14, 2003Publication date: February 19, 2004Inventors: Yusuke Muraoka, Takashi Miyake, Kimitsugu Saito, Takahiko Ishii, Yoshihiko Sakashita, Katsumi Watanabe
