Patent number: 6814507Abstract: A substrate treating apparatus includes a heat-treating unit having a cooling unit and a local transport mechanism. The local transport mechanism, in time of standby, is placed in a standby position inside the cooling unit. The local transport mechanism in the standby position influences, and is influenced by, the environment outside the heat-treating unit less than where the local transport mechanism is kept on standby outside the heat-treating unit. Variations in substrate treating precision due to such adverse influences are reduced to perform substrate treatment with high precision.Type: GrantFiled: March 20, 2003Date of Patent: November 9, 2004Assignee: Dainippon Screen Mfg. Co., Ltd.Inventor: Yukihiko Inagaki

Patent number: 6802934Abstract: Two load lock chambers 130 and 132 are arranged between a first transfer chamber 122 and a second transfer chamber 133. Each of the load lock chambers is capable of accommodating a single wafer W. The first transfer chamber 122 is provided with a first transfer unit 124 having two substrate holders 124a, 124b each capable of holding a single object to be processed, in order to transport the wafer W among a load port site 120, the first load lock chamber 130, the second load lock chamber 132 and a positioning unit 150. The second transfer chamber 133 is provided with a second transfer unit 156 having two substrate holders 156a, 156b each capable of holding the single object to be processed, in order to transport the wafer between the first load lock chamber 130, the second load lock chamber 132 and respective vacuum processing chambers 158 to 164. Since the volume of each load lock chamber can be minimized, it is possible to perform the prompt control of atmospheres in the load lock chambers.Type: GrantFiled: March 5, 2003Date of Patent: October 12, 2004Assignee: Tokyo Electron LimitedInventors: Hiroaki Saeki, Keiichi Matsushima, Teruo Asakawa, Masaki Narushima

Patent number: 6799932Abstract: A processor for processing articles, such as semiconductor wafers, in a substantially clean atmosphere is set forth. The processor includes an enclosure defining a substantially enclosed clean processing chamber and at least one processing station disposed in the processing chamber. An interface section is disposed adjacent an interface end of the enclosure. The interface section includes at least one interface port through which a pod containing articles for processing are loaded or unloaded to or from the processor. The interface section is hygienically separated from the processing chamber since the interface section is generally not as clean as the highly hygienic processing chamber. An article extraction mechanism adapted to seal with the pod is employed. The mechanism is disposed to allow extraction of the articles contained within the pod into the processing chamber without exposing the articles to ambient atmospheric conditions in the interface section.Type: GrantFiled: June 9, 2003Date of Patent: October 5, 2004Assignee: Semitool, Inc.Inventors: Jeffry A.
