Publication number: 20140027289Abstract: The present invention generally relates to a substrate support for use in a substrate processing chamber. A roughened substrate support reduces arcing within the chamber and also contributes to uniform deposition on the substrate. The roughening can occur in two steps. In a first step, the substrate support is bead blasted to initially roughen the surfaces. Then, the roughened surface is bead blasted with a finer grit to produce a substrate support with a surface roughness of between about 707 micro-inches and about 837 micro-inches. Following the surface roughening, the substrate support is anodized.Type: ApplicationFiled: July 17, 2013Publication date: January 30, 2014Applicant: APPLIED MATERIALS, INC.Inventors: Dongsuh LEE, William N. STERLING, Beom Soo PARK, Soo Young CHOI

Publication number: 20120237682Abstract: A system for handling masked substrates comprising a chamber having a pedestal for supporting a substrate, and a chuck for supporting a mask in relation to a substrate. The system may include an alignment system operable to confirm alignment of the mask and the substrate. A method of positioning a mask on a substrate in a chamber comprises supporting the mask with a chuck disposed in the chamber and supporting the substrate with a pedestal disposed in the chamber. The method may further comprise aligning one or more reference points on the mask with one or more reference points on the substrate and positioning the mask on the substrate using at least one of the chuck and the pedestal.Type: ApplicationFiled: March 7, 2012Publication date: September 20, 2012Applicant: Applied Materials, Inc.Inventors: Ilyoung Richard Hong, William N.

Patent number: 8251009Abstract: The present invention generally includes a shadow frame with alignment inserts that may permit the shadow frame to be properly aligned on the susceptor. The shadow frame may have one or more alignment inserts. The alignment inserts may be coupled to a cavity formed in the bottom surface of the shadow frame. The alignment inserts may be shaped to receive an alignment button that may be present on the susceptor. Thus, as the susceptor raises to the processing position and retrieves the shadow frame, the shadow frame may align properly on the susceptor.Type: GrantFiled: May 13, 2009Date of Patent: August 28, 2012Assignee: Applied Materials, Inc.Inventors: Lan Duong, William N. Sterling, John M. White

Patent number: 8206075Abstract: In certain aspects, a load lock chamber is provided that includes a body having at least one sealing surface wall including a sealing surface. The sealing surface wall has an opening adjacent the sealing surface adapted to input or output a substrate. The body further includes a plurality of side walls. The load lock chamber also includes a top coupled to the body. The top includes one or more openings that divide the top into a first portion and a second portion. The load lock chamber further includes one or more top sealing members adapted to cover each opening of the top. Each top sealing member absorbs a movement of the first portion of the top relative to the second portion of the top. Numerous other aspects are provided.Type: GrantFiled: June 2, 2005Date of Patent: June 26, 2012Assignee: Applied Materials, Inc.Inventors: John M. White, Shinichi Kurita, William N. Sterling, Yoshiaki Tanase

Publication number: 20100282603Abstract: A method and apparatus for making a heated substrate support assembly used in a processing chamber is provided. The processing chamber includes a substrate support assembly, having a first plate and a second plate with grooves disposed therein for receiving one or more heating elements, and a power source for heating the substrate support assembly. A first surface of the first plate and a second surface of the second plate include one or more matching structures disposed thereon, such that both plates can be compressed together by isostatic compression and form into a plate-like structure for supporting a substrate during substrate processing. In another embodiment, the first and second plates are compressed by applying pressure all around. In still another embodiment, compressing the first and second plates is performed at elevated temperature.Type: ApplicationFiled: July 28, 2010Publication date: November 11, 2010Inventors: William N.

Patent number: 7641247Abstract: Generally, an end effector assembly for a substrate transfer robot is provided. In one embodiment, an end effector assembly for supporting a quadrilateral substrate during substrate transfer includes an end effector having an inner edge support disposed on a first end and a first outer edge support disposed on a distal end. The first end of the end effector is adapted for coupling to a robot linkage. The first inner edge support has a face that is oriented parallel to and facing the face of the first outer edge support. This configuration of edge supports captures the substrate to the end effector thereby minimizing substrate slippage during transfer. In another embodiment, lateral guides may be utilized to further enhance capturing the substrate along the edges of the substrate open between the inner and outer edge supports.Type: GrantFiled: December 17, 2002Date of Patent: January 5, 2010Assignee: Applied Materials, Inc.Inventors: Wendell T.
