Patent number: 8382088Abstract: A substrate processing apparatus is disclosed for bringing a substrate from a carrier, by a substrate transfer portion inside a transfer chamber, into a processing module to perform a process therein. The substrate processing apparatus includes a substrate storing chamber coupled to an exterior of the transfer chamber via a transfer opening to be in communications with the transfer chamber; a first storing shelf in the substrate storing chamber to store substrates for a first storing purpose; a second storing shelf in the substrate storing chamber to store substrates for a second storing purpose different from the first storing purpose; and a shifting mechanism that shifts the first and the second storing shelves to position a substrate storing area of one of the first and the second storing shelves so that substrate transferring is enabled between the substrate storing area and the substrate transfer portion via the transfer opening.Type: GrantFiled: March 28, 2008Date of Patent: February 26, 2013Assignee: Tokyo Electron LimitedInventor: Keisuke Kondoh

Patent number: 8376339Abstract: A positioner includes a housing, a table, a drive portion, a cylinder, a first winder, and a first cord. The cylinder includes a first opening at the rotation center of the table, and a second opening opposite and connected to the first opening. The first winder is disposed outside the second opening of the cylinder. The first cord includes a first lead-out portion and a first wound portion. The first lead-out portion enters the second opening, passes through the cylinder, and is led out from the table. The first wound portion is wound around the first winder according to the rotation of the table. Thus, the positioner can increase the number of air tubes or wires led out onto the table without increasing its size.Type: GrantFiled: July 8, 2009Date of Patent: February 19, 2013Assignee: Panasonic CorporationInventors: Takashi Nagai, Wataru Takahashi, Takayasu Ohara, Seiji Iwai

Patent number: 8376334Abstract: A tool to hold objects by suction includes a glue free gasket structure on its handling surface. The gasket structure includes a gland formed below the handling surface having an approximate dovetail section with a narrow opening at the handling surface defining a suction area, and a gasket inserted in the gland. The gasket has a shoulder portion that conforms to the shoulder portion of the dovetail section of the gland, and a sealing lip protruding through the narrow opening at the handling surface. The gasket fits movably in the gland, and is self-aligning to compensate for variations in the space between the holding surface and the object being handled. This gasket structure is especially useful for devices to cool injection molded parts.Type: GrantFiled: October 26, 2011Date of Patent: February 19, 2013Assignee: Swedcord Development ABInventor: Göran Dalvander

Patent number: 8371564Abstract: A suction apparatus 1 holds a wafer W by performing vacuum-suctioning on the wafer W. The suction apparatus 1 comprises a suction substrate 2. The suction substrate 2, which is rigid, comprises a plurality of pin-like protrusions 2a formed so that the tip-end faces (upper surfaces) thereof are the same height. An elastic coating layer is coated by way of an undercoat layer 4 on the tip-end faces of the protrusions 2a. When the wafer W is suctioned, even if a foreign matter is interposed between the wafer W and the suction surface, because the foreign matter embeds itself into the coating layer 3, the planarization of the wafer W is improved. In addition, because the coating layer 3 can be made comparatively thinner, undulations in the wafer W can be reduced and, to that end, the planarization of the wafer W in the suctioned state can be improved.Type: GrantFiled: February 17, 2006Date of Patent: February 12, 2013Assignee: Nikon CorporationInventor: Naoki Asada

Patent number: 8371565Abstract: A clamping device for clamping a substrate with a first surface and a second surface includes a supporting plate and a number of clamping units. The supporting plate includes a base portion and an engaging portion. The base portion includes a base surface. The engaging portion protrudes from the base surface of the base portion and includes an engaging surface facing away from the base surface. The supporting plate defines a through hole in the engaging surface. The supporting plate is configured for supporting the substrate on the engaging surface of the engaging portion. The clamping units are configured for clamping the substrate on the supporting plate such that the engaging surface of the engaging portion engaging surface is substantially coplanar with the first surface of the substrate.Type: GrantFiled: August 19, 2010Date of Patent: February 12, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Tai-Sheng Tsai
