Patent number: 8802454Abstract: A method for testing TSVs is provided. A plurality of TSVs is formed in a semiconductor substrate. Wiring layers and a first contact array are formed on the front-side of the substrate. The wiring layers couple each of the TSVs to a respective contact of the first contact array. Conductive adhesive is deposited over the first contact array. The conductive adhesive electrically couples contacts of the first contact array. A carrier is bonded to the front-side of the substrate with the conductive adhesive. After bonding the carrier to the substrate, the back-side of the substrate is thinned to expose each of the TSVs on the back-side of the substrate. A second contact array is formed, having a contact coupled to each respective TSV. Conductivity and connections of the TSVs, wiring layers, and contacts are tested by testing for conductivity between contacts of the second contact array.Type: GrantFiled: December 20, 2011Date of Patent: August 12, 2014Assignee: Xilinx, Inc.Inventors: Arifur Rahman, Henley Liu, Cheang-Whang Chang, Myongseob Kim, Dong W.

Patent number: 8772177Abstract: A wafer surface of a semiconductor wafer to be used as a device active region is mirror-polished, and an outer peripheral portion of the mirror-polished wafer surface is further polished, thereby forming an edge roll-off region between the device active region of the wafer surface and a beveled portion formed at the wafer edge. The edge roll-off region has a specific roll-off shape corresponding to an edge roll-off of the oxide film to be formed in a device fabrication process. Thus, a semiconductor wafer can be provided in which reduction in the thickness of an oxide film on the outer peripheral portion of the wafer in a CMP process can be prevented while maintaining high flatness of the wafer surface.Type: GrantFiled: December 13, 2010Date of Patent: July 8, 2014Assignee: Sumco CorporationInventor: Sumihisa Masuda
