Patent number: 9711382Abstract: Embodiments described herein generally relate to apparatus for processing substrates. The apparatus generally include a process chamber including a lamp housing containing lamps positioned adjacent to an optically transparent window. Lamps within the lamp housing provide radiant energy to a substrate positioned on the substrate support. Temperature control of the optically transparent window is facilitated using cooling channels within the lamp housing. The lamp housing is thermally coupled to the optically transparent window using compliant conductors. The compliant conductors maintain a uniform conduction length irrespective of machining tolerances of the optically transparent window and the lamp housing. The uniform conduction length promotes accurate temperature control. Because the length of the compliant conductors is uniform irrespective of machining tolerances of chamber components, the conduction length is the same for different process chambers.Type: GrantFiled: April 16, 2014Date of Patent: July 18, 2017Assignee: APPLIED MATERIALS, INC.Inventors: Joseph M.

Patent number: 7718929Abstract: A substrate is made of a crystallized glass having translucency and an average linear thermal expansion coefficient of ?5×10?7/° C. at 30 to 500° C. The substrate has a first surface (working surface) of a smooth surface having a surface roughness Rmax of less than 0.5 ?m, and a second surface (non-working surface) of a rough surface having a surface roughness Rmax of 4 ?m. A light shielding layer consisting of a light shielding film and an antioxidant film is formed on the second surface of the substrate through sputtering.Type: GrantFiled: November 3, 2006Date of Patent: May 18, 2010Assignee: Nippon Electric Glass Co., Ltd.Inventors: Narutoshi Shimatani, Toshimasa Kanai, Ukon Ishihara, Takeshi Nagata, Tsutomu Imamura
