Patent number: 7898089Abstract: The present invention provides an apparatus and method for use in processing semiconductor workpieces. The new apparatus and method allows for the production of thinner workpieces that at the same time remain strong. Particularly, a chuck is provided that includes a body, a retainer removeably attached to the body and a seal forming member. When a workpiece is placed on the chuck body and the retainer is engaged to the body, a peripheral portion of the back side of the workpiece is covered by the retainer while an interior region of the back side of the workpiece is exposed. The exposed back side of the workpiece is then subjected to a wet chemical etching process to thin the workpiece and form a relatively thick rim comprised of semiconductor material at the periphery of the workpiece. The thick rim or hoop imparts strength to the otherwise fragile, thinned semiconductor workpiece.Type: GrantFiled: October 26, 2007Date of Patent: March 1, 2011Assignee: Semitool, Inc.Inventors: Kert L. Dolechek, Raymon F. Thompson

Patent number: 7625821Abstract: The present invention provides system and apparatus for use in processing wafers. The new system and apparatus allows for the production of thinner wafers that at same time remain strong. As a result, the wafers produced by the present process are less susceptible to breaking. The unique system also offers an improved structure for handling thinned wafers and reduces the number of processing steps. This results in improved yields and improved process efficiency.Type: GrantFiled: May 26, 2006Date of Patent: December 1, 2009Assignee: Semitool, Inc.Inventors: Kert L. Dolechek, Raymon F. Thompson

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. Davis, Kert L. Dolechek, Gary L. Curtis

Patent number: 6736148Abstract: An automated semiconductor processing system has an indexer bay perpendicularly aligned with a process bay within a clean air enclosure. An indexer in the indexer bay provides stocking or storage for work in progress semiconductor wafers. Process chambers are located in the process bay. A process robot moves between the indexer bay and process bay to carry semi-conductor wafers to and from the process chambers. The process robot has a robot arm vertically moveable along a lift rail. Semiconductor wafers are carried offset from the robot arm, to better avoid contamination. The automated system is compact and requires less clean room floor space.Type: GrantFiled: May 22, 2001Date of Patent: May 18, 2004Assignee: Semitool, Inc.Inventors: Jeffry A. Davis, Kevin P.

The article processor also preferably includes an article insertion mechanism adapted to seal with a pod in the interface section. The article insertion mechanism allows insertion of the articles into the pod after processing by at least one processing station.Type: GrantFiled: July 25, 2002Date of Patent: November 25, 2003Assignee: Semitool, Inc.Inventors: Jeffry A.
