Patent number: 8912048Abstract: A method of fabricating a semiconductor device includes attaching a semiconductor substrate to a carrier using a carrier fixing layer, where the semiconductor substrate including a plurality of semiconductor chips. The method further includes forming gaps between adjacent ones of the chips. The gaps may be formed using one or more chemicals or light which act to remove portions of the semiconductor substrate to expose the carrier fixing layer. Additional portions of the carrier fixing layer are then removed to allow for removal of the chips from the carrier.Type: GrantFiled: March 14, 2013Date of Patent: December 16, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Jong-Youn Kim, Ji-Hwang Kim, Hae-Jung Yu, Cha-Jea Jo

Patent number: 7136366Abstract: In the preferred embodiment, the transmission length of the non-full rate frame is shortened frame in order for the mobile terminal 100 to monitor other frequencies with a single receiver. Modulated symbols of non-full rate frame are transmitted with reduced repetition maintaining the sum of repeated symbol energy. Generally, for 1/n (n=2,4,8) length transmission, 1/m (m?n) rate frame repeated m/n times and transmitted with n/m symbol energy of the full rate frame. The system may use rate limitation to generate a non-full rate frame. A position of the transmitted symbols may be randomized by a mobile specific predetermined random code to minimize interference between terminals different from each other. For intensive frequency scanning and synchronization signal transmission, non-transmitting period can be assigned for successive frames of some interval. For 1/n (n=2,4,8) length successive transmission, the starting position of the transmitted symbols are staggered by 1/n frame time in each frame.Type: GrantFiled: December 18, 2001Date of Patent: November 14, 2006Assignee: LG Electronics Inc.Inventor: Jong-Youn Kim
