Patent number: 8338280Abstract: Embodiments relate to a method for fabricating nano-wires in nano-devices, and more particularly to nano-device fabrication using end-of-range (EOR) defects. In one embodiment, a substrate with a surface crystalline layer over the substrate is provided and EOR defects are created in the surface crystalline layer. One or more fins with EOR defects embedded within is formed and oxidized to form one or more fully oxidized nano-wires with nano-crystals within the core of the nano-wire.Type: GrantFiled: July 8, 2010Date of Patent: December 25, 2012Assignees: GLOBALFOUNDRIES Singapore Pte. Ltd., Nanyang Technological UniversityInventors: Dexter Tan, Kin Leong Pey, Sai Hooi Yeong, Yoke King Chin, Kuang Kian Ong, Chee Mang Ng

Patent number: 8268733Abstract: A method of forming a device is presented. The method includes providing a wafer having an active surface and dividing the wafer into a plurality of portions. The wafer is selectively processed by localized heating of a first of the plurality of portions. The wafer is then repeatedly selectively processed by localized heating of a next of the plurality of portions until all plurality of portions have been selectively processed.Type: GrantFiled: August 7, 2009Date of Patent: September 18, 2012Assignees: Nanyang Technological University, National University of Singapore, Globalfoundries Singapore Pte. Ltd.Inventors: Dexter Tan, Chee Chong Lim, Sai Hooi Yeong, Chee Mang Ng

Patent number: 8101487Abstract: A method for fabricating a semiconductor device is presented. The method includes providing a substrate and forming a gate stack over the substrate. A first laser processing to form vacancy rich regions within the substrate on opposing sides of the gate stack is performed. The vacancy rich regions have a first depth from a surface of the substrate. A first implant causing end of range defect regions to be formed on opposing sides of the gate stack at a second depth from the surface of the substrate is also carried out, wherein the first depth is proximate to the second depth.Type: GrantFiled: May 15, 2009Date of Patent: January 24, 2012Assignees: Nanyang Technological University, National University of Singapore, GLOBALFOUNDRIES Singapore Pte. Ltd.Inventors: Dexter Xueming Tan, Benjamin Colombeau, Clark Kuang Kian Ong, Sai Hooi Yeong, Chee Mang Ng, Kin Leong Pey

Publication number: 20110048957Abstract: A structure and method for forming a relatively thin diffusion barrier/seed bilayer for copper metallization in an electronic device is disclosed. A single layer of an alloy is formed over a dielectric (and possibly the copper layer). The alloy includes a copper platable metal (e.g., ruthenium) and a nitride forming material (e.g., tungsten) and nitrogen. The alloy layer is annealed, and the alloy naturally segregates into two layers. The first layer is a barrier layer including the nitride forming material and nitrogen. The second layer is a seed layer including the copper platable metal.Type: ApplicationFiled: September 1, 2009Publication date: March 3, 2011Applicants: Chartered Semiconductor Manufacturing, Ltd., Nanyang Technological UniversityInventors: Martina Damayanti, Thirumany Sritharan, Chee Mang Ng
