Publication number: 20140170780Abstract: Methods for repairing a carbon depleted low-k material in a low-k dielectric film layer of a semiconductor wafer include providing a proximity head with a plurality of nozzles disposed on a surface of the proximity head. A repair chemistry having a hydrocarbon group is applied to a portion of the semiconductor wafer that includes carbon depleted low-k material, through the proximity head. The application is used to deliver carbon from the repair chemistry into the carbon depleted low-k material so as to cause replacement of a hydrogen ion within a hydroxyl group in the carbon depleted low-k material with carbon containing hydrocarbon group of the repair chemistry. The carbon containing hydrocarbon group forms a bond with suspended oxygen ion of the hydroxyl group thereby substantially repairing the low-k dielectric layer. The semiconductor wafer is then moved to expose other portions of the semiconductor wafer to the repair chemistry.Type: ApplicationFiled: February 24, 2014Publication date: June 19, 2014Applicant: LAM RESEARCH CORPORATIONInventors: Seokmin Yun, Mark Wilcoxson, John M. deLarios

Patent number: 8388762Abstract: A method and system for cleaning opposed surfaces of a semiconductor wafer having particulate matter thereon. The method includes generating relative movement between a fluid and the substrate. The relative movement is in a direction that is transverse to a normal to one of the opposed surfaces and creates two spaced-apart flows. Each of the flows is adjacent to one of the opposed surfaces that is different from the opposed surface that is adjacent to the remaining flow of the plurality of flows. The fluid has coupling elements entrained therein, and the relative movement is established to impart sufficient drag upon a subset of the coupling elements to create movement of the coupling elements of the subset within the fluid. In this manner, a quantity of the drag is imparted upon the particulate matter to cause the particulate matter to move with respect to the substrate.Type: GrantFiled: May 2, 2007Date of Patent: March 5, 2013Assignee: Lam Research CorporationInventors: Erik M.
