Publication number: 20130115773Abstract: When forming sophisticated high-k metal gate electrode structures on the basis of a replacement gate approach, pronounced loss of the interlayer dielectric material may be avoided by inserting at least one surface modification process, for instance in the form of a nitridation process. In this manner, leakage paths caused by metal residues formed in the interlayer dielectric material may be significantly reduced.Type: ApplicationFiled: November 4, 2011Publication date: May 9, 2013Applicant: GLOBALFOUNDRIES INC.Inventors: Rohit Pal, Rolf Stephan, Andreas Ott

Patent number: 8343875Abstract: Methods for forming a semiconductor device include forming self-aligned trenches, in which a first set of trenches is used to align a second set of trenches. Methods taught herein can be used as a pitch doubling technique, and may therefore enhance device integration. Further, employing a very thin CMP stop layer, and recessing surrounding materials by about an equal amount to the thickness of the CMP stop layer, provides improved planarity at the surface of the device.Type: GrantFiled: January 10, 2012Date of Patent: January 1, 2013Assignee: Micron Technology, Inc.Inventors: Werner Juengling, Richard Lane

Publication number: 20120083125Abstract: Planarization methods include depositing a mask material on top of an overburden layer on a semiconductor wafer. The mask material is planarized to remove the mask material from up areas of the overburden layer to expose the overburden layer without removing the mask material from down areas. The exposed overburden layer is wet etched and leaves a thickness remaining over an underlying layer. Remaining portions of the mask layer and the exposed portions of the overburden layer are planarized to expose the underlying layer.Type: ApplicationFiled: January 25, 2011Publication date: April 5, 2012Applicants: JSR CORPORATION, INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Leslie Charns, John M.
