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: 8242872Abstract: Embodiments of the invention provide a transformer comprising: a first coil element having a transverse axis along a transverse direction, the first coil element having p turns where p is greater than or equal to 1; and a second coil element having a transverse axis generally parallel to the transverse axis of the first coil element, the second coil element having n turns, where n is greater than or equal to 5p; wherein the first and second coil elements are arranged to provide electromagnetic coupling between the coil elements along a portion of a length of the second coil element in both a transverse direction parallel to the transverse axes and a lateral direction, wherein the lateral direction is a direction normal to the transverse axes.Type: GrantFiled: July 19, 2007Date of Patent: August 14, 2012Assignee: GLOBALFOUNDRIES Singapore Pte. Ltd.Inventors: Chee Chong Lim, Kok Wai Chew, Kiat Seng Yeo, Suh Fei Lim, Manh Anh Do, Lap Chan

Patent number: 7570144Abstract: An integrated transformer structure includes a first coil element associated with a transverse axis, the first coil element having at least one turn. The first coil element includes a first portion provided on a first lateral level, and a second portion provided on a second lateral level. The first and second lateral levels being mutually spaced apart along said transverse axis. The first and second portions being displaced laterally from said axis by different respective distances. At least one crossover portion of the first coil element, in which the first coil element being configured to provide a conducting path through at least a portion of the first portion of the first coil element to the crossover portion, through the crossover portion and subsequently through at least a portion of the second portion of the first coil element, in which any change of flow direction along said path is less than 90° in a lateral direction.Type: GrantFiled: May 18, 2007Date of Patent: August 4, 2009Assignees: Chartered Semiconductor Manufacturing, Ltd., Nanyang Technological UniversityInventors: Chee Chong Lim, Kok Wai Chew, Kiat Seng Yeo, Suh Fei Lim, Manh Anh Do, Lap Chan
