Publication number: 20040062633Abstract: In a semiconductor fabrication facility, a conveyor transports substrate carriers. The substrate carriers are unloaded from the conveyor and loaded onto the conveyor without stopping the conveyor. A load and/or unload mechanism lifts the substrate carriers from the conveyor during unloading operations, while matching the horizontal speed of the conveyor. Similarly, during loading operations, the load/unload mechanism lowers a substrate carrier into engagement with the conveyor while matching the horizontal speed of the conveyor. Individual substrates, without carriers, may be similarly loaded and/or unloaded from a conveyor.Type: ApplicationFiled: August 28, 2003Publication date: April 1, 2004Applicant: APPLIED MATERIALS, INC.Inventors: Michael Robert Rice, Robert B.

Patent number: 6709218Abstract: The present invention generally provides a robot blade which provides a plurality of semi-conductive or conductive contacts disposed at least partially on the surface of the blade to support a substrate above the blade. The contacts are preferably located inwardly from the edge of the blade and toward the center of the blade to provide a collection area on the blade to capture any particles which may form. The blade is preferably made of a semi-conductive material, such as alumina or other semi-conductive material, to provide an electrical flow path through the contact(s) to discharge any electrical charge which may build up on the substrate during processing.Type: GrantFiled: June 3, 1999Date of Patent: March 23, 2004Assignee: Applied Materials, Inc.Inventors: Frederik W.

Publication number: 20030202865Abstract: A wafer handler having a central body with a first end and a central axis of rotation is provided. A first end effector, adapted to support a first wafer, is rotatably coupled to the first end of the central body so as to define a first axis of rotation between the central body and the first end effector. Optionally, a second end effector adapted to support a second wafer is rotatably coupled to the second end of the central body so as to define a second axis of rotation between the central body and the second end effector. When the central body is rotated about the central axis of rotation in a first direction over a first angular distance, the first end effector simultaneously rotates about the first axis of rotation and the optional second end effector rotates about the second axis of rotation. Both end effectors are rotated over a second angular distance that is greater than the first angular distance. One or more of the end effectors may be pocketless.Type: ApplicationFiled: April 25, 2002Publication date: October 30, 2003Applicant: Applied Materials, Inc.Inventors: Hari Ponnekanti, Vinay K.

Publication number: 20030110649Abstract: A jig used in a substrate carrier handling robot calibration process has features that emulate the overhead transport flange and the bottom surface of a standard substrate carrier. The jig further includes features that are allowed to interact with sensors associated with substrate carrier storage locations and/or sensors associated with an end effector of the substrate carrier handling robot. In calibrating the substrate carrier handling robot the jig is juxtaposed with a substrate carrier storage location. The end effector of the robot is moved relative to the substrate carrier storage location and the above-mentioned sensors are allowed to interact with the jig. A controller for the robot detects locations of the end effector at times when the sensors interact with the jig.Type: ApplicationFiled: December 19, 2001Publication date: June 19, 2003Applicant: APPLIED MATERIALS, INC.Inventors: Jeffrey C.
