Publication number: 20210020441Abstract: A method for etching features in a stack below a mask with features is provided. A fill layer is deposited on the mask, wherein the fill layer fills the features of the mask. The fill layer is etched back to expose the mask. The mask is selectively removed with respect to the fill layer. The stack is etched using the fill layer as a mask.Type: ApplicationFiled: March 29, 2019Publication date: January 21, 2021Inventors: Juan VALDIVIA, Yasushi ISHIKAWA, Yoko YAMAGUCHI

Patent number: 10763142Abstract: A system for controlling a condition of a wafer processing chamber is disclosed. According the principles of the present disclosure, the system includes memory and a first controller. The memory stores a plurality of profiles of respective ones of a plurality of first control elements. The plurality of first control elements are arranged throughout the chamber. The first controller determines non-uniformities in a substrate processing parameter associated with the plurality of first control elements. The substrate processing parameter is different than the condition of the chamber. The first controller adjusts at least one of the plurality of profiles based on the non-uniformities in the substrate processing parameter and a sensitivity of the substrate processing parameter to the condition.Type: GrantFiled: September 21, 2015Date of Patent: September 1, 2020Assignee: LAM RESEARCH CORPORATIONInventors: Marcus Musselman, Juan Valdivia, III, Hua Xiang, Andrew D. Bailey, III, Yoko Yamaguchi, Qian Fu, Aaron Eppler

Patent number: 8394723Abstract: A method for adjusting the geometry of photomask patterns is provided. Such adjusted pattern can be employed to achieve pattern doubling in subsequent layers. A patterned photoresist mask is provided over an underlayer. A polymer layer is placed over the mask. The mask is selectively trimmed to generate individual mask features having an increased aspect ratio. Subsequent pattern layers can be formed on the trimmed mask pattern to generate a hard mask having increased pattern density. The hard mask is selectively etched and the material of the trimmed mask pattern is removed. The underlayer is then etched to achieve pattern transfer from the hard mask to the underlayer to achieve a final double density pattern.Type: GrantFiled: January 7, 2010Date of Patent: March 12, 2013Assignee: Lam Research CorporationInventors: Juan Valdivia, Shibu Gangadharan, Dave March, Charles Potter

Patent number: 4428538Abstract: A grinding disc for a disc refiner is disclosed. The grinding disc is comprised of a plurality of packs of strips. Each pack of strips is comprised of a plurality of parallel grinding strips which alternate with intermediate strips. The rear-to-front grinding surface height of the grinding strips is greater than that of the intermediate strips. Annular supporting rings define the radially inward and outward ends of the grinding strips. The grinding strips extend generally radially of the grinding disc. In an alternate embodiment, the intermediate strips are of meandering shape, whereby one intermediate strip extends between pluralities of adjacent grinding strips. The grinding and intermediate strips of a pack thereof are welded together and are welded to the supporting rings. An additional ring may be positioned to the rear of the strips intermediate the radially inward and outward ends thereof.Type: GrantFiled: July 1, 1981Date of Patent: January 31, 1984Assignee: J. M.
