Publication number: 20140041805Abstract: Provided is a substrate processing apparatus in which the concentration of processing gas is matched in a substrate surface at the time of initiating the ejection of the processing gas from a gas supply unit. The gas supply unit is provided with a gas ejecting surface facing the wafer disposed on a disposition unit. The gas supply unit is also provided with gas flow paths, and a flow path length and a flow path diameter of the diverged gas flow paths are set such that periods of time for gas flowing from a gas supply hole to a plurality of gas ejecting holes formed on the gas ejecting surface are matched with each other. Thus, the timings when the processing gas reaches the respective gas ejecting holes immediately after initiating the ejection of the processing gas are matched.Type: ApplicationFiled: August 5, 2013Publication date: February 13, 2014Applicant: TOKYO ELECTRON LIMITEDInventors: Yasuhiro KUGA, Masashi ITONAGA

Patent number: 6551448Abstract: The present invention is an apparatus for operating heat processing to a substrate, and comprises a heating plate to mount and heat the substrate thereon, a supporting member to support a lower surface of a periphery of the heating plate, and a supporter to support the supporting member. The supporting member has a stepped portion to surround an outer peripheral surface of the heating plate. The supporting member is fixed to the supporter by a fixing member penetrating through the stepped portion in a vertical direction. The fixing member is provided between an inner peripheral surface of the stepped portion and the outer peripheral surface of the heating plate. According to the present invention, since the fixing member is provided between the outer peripheral surface of the heating plate and the inner peripheral surface of the stepped portion, the supporting member does not exist between the fixing member and the outer peripheral surface of the heating plate.Type: GrantFiled: March 8, 2001Date of Patent: April 22, 2003Assignee: Tokyo Electron LimitedInventors: Yasuhiro Kuga, Mitsuhiro Tanoue, Kouichirou Tanaka
