摘要:
An apparatus for processing wafers one at a time. The apparatus has a vacuum chamber 1 into which wafers are loaded through a pair of loadlocks 3, 4 which are spaced one above the other. A robot within the vacuum chamber 1 has a pair of gripper arms 22, 29 which are moveable along and rotatable about a vertical axis 23 so as to be moveable between the loadlocks 3, 4 and a wafer processing position. Each of the loadlocks 3, 4 has a vertically moveable portion 8, 26 which is moveable away from the remainder of the loadlock to provide access in a horizontal plane for one of the gripper arms 22, 29.

Eine Bearbeitungsanlage modularen Aufbaus für flächige Substrate unter atmosphärischen Sonderbedingungen sieht gleich gerichtete, unabhängig voneinander längs der in Reihe angeordneten Module verlaufende Führungsbahnen vor, auf denen Transfereinheiten angeordnet sind, die jeweils auf die Modulreihe zu auskragende Transferkammern aufweisen, welche Reinräume bilden und unabhängig voneinander gegeneinander verfahrbar sowie mit jeweiligen Modulen zu verbinden sind, die ihrerseits bevorzugt bezüglich ihrer Übergabeöffnungen nach deren Höhenlage gruppiert und auf die Höhenlage einer jeweiligen Transferkammer abgestimmt angeordnet sind.
摘要:
Disclosed is, among other things, a method in which a workpiece (14) is fastened to a workpiece support (12) with the aid of connecting means (18, 20), the workpiece (14) and the workpiece support (12) being joined together using an annular connecting means (18, 20). The resulting compound is machined, whereupon the machined workpiece (14) is separated from the workpiece support (12), making it possible to create a particularly simple machining process.
摘要:
A high-speed wafer-processing apparatus and method that employs a vacuum chamber having at least two wafer transport robots and a process station. The vacuum chamber interfaces with a number of single-wafer load locks that are loaded and unloaded one wafer at a time by a robot in atmosphere. Four load locks are sized to allow for a gentle vacuum cycling of each wafer without significant pumpdown delays. The robots in the vacuum chamber move wafers sequentially from one of the load locks to a process station for processing and then to another one of the load locks for unloading by the atmospheric robot.

A gate valve (20) for a semiconductor processing system includes a housing (21) forming a plurality of passages (22A to 22D) arrayed in a first direction. The passages respectively have ports (23A to 23D) facing a first predetermined side in a second direction perpendicular to the first direction. The ports are respectively provided with valve seats (25A to 25D) at gradually set back positions in the second direction, as being closer to a second predetermined side in the first direction. Valve plates (24A to 24D) are arrayed in the second direction to open/close the ports. The valve plates are slid by an actuating mechanism (30A to 30D) .
摘要:
A dual chamber apparatus including a first chamber and a second chamber which is configured to be coupled to the first chamber at an interface. Each of the first chamber and the second chamber has a transfer opening located at the interface. An insulating plate is located on one of the first chamber and the second chamber at the interface and is configured to have a low thermal conductivity such that the first chamber and the second chamber can be independently controlled at different temperatures when the first chamber and the second chamber are coupled together. Additionally, the apparatus may include an alignment device and/or a fastening device for fastening the first chamber to the second chamber. In embodiments, the insulating plate may be constructed of Teflon. Further, the first chamber may be a chemical oxide removal treatment chamber and the second chamber may be a heat treatment chamber.

A system uses a portable carrier (32) for transporting wafers in a particle-free environment. A cassette (34) within the carrier is delivered to a clean load lock (22). A mini-environment (52) defines an interior region (54) for the reception of the carrier. Transfer mechanisms (68, 70) retrieve the cassette from the carrier and move it into the load lock chamber. A hood (78) of the mini-environment is movable between lowered and raised positions while maintaining a seal with its walls. Laminar flow air is continually directed through the mini-environment and filtered to remove particles from the wafers in the cassette.
摘要:
An apparatus in combination with a load lock of an ion implanter comprises a cover adjacent an isolation valve slot of the load lock. The cover defines an aperture generally conforming to the size and shape of the load, or wafer, within the load lock with sufficient clearance for a robot arm to pick the wafer from within the load lock and transfer the wafer to the implant chamber. The cover masks a portion of the slot so as to reduce the opening between the load lock and the implant chamber of the ion implanter. The smaller opening reduces the pressure burst from the load lock to the implant chamber when the isolation valve and slot is opened. By reducing the pressure burst, the cover can shorten the recovery time for the implant chamber to reach operating pressure.
