Patent number: 8298941Abstract: A method of manufacturing a semiconductor device includes, but is not limited to, the following processes. A seed layer is formed over a substrate. The seed layer includes first, second, and third portions. A first electrode covering the first portion of the seed layer is formed without forming an electrode on the second and third portions of the seed layer. The third portion of the seed layer is removed so that the first and second portions remain over the substrate, and the first and second portions are separated from each other.Type: GrantFiled: February 14, 2011Date of Patent: October 30, 2012Assignee: Elpida Memory, Inc.Inventor: Masahiro Yamaguchi

Patent number: 8298943Abstract: A method for patterning self-aligned vias in a dielectric. The method includes forming a first trench partially through a hard mask, where the trench corresponds to a desired wiring path in the dielectric. The trench should be formed on a sub-lithographic scale. Form a second trench, also of a sub-lithographic scale, that intersects the first trench. The intersection forms a pattern extending through the depth of the hard mask, and corresponds to a via hole in the dielectric. The via hole is etched into the dielectric through the hard mask. The first trench is extended through the hard mask and the exposed area is etched to form the wiring path, which intersects the via hole. Conductive material is deposited to form a sub-lithographic via and wiring. This method may be used to form multiple vias of sub-lithographic proportions and with a sub-lithographic pitch.Type: GrantFiled: May 27, 2011Date of Patent: October 30, 2012Assignee: International Business Machines CorporationInventors: John Christopher Arnold, Sean D. Burns, Sivananda K. Kanakasabapathy, Yunpeng Yin
