Patent number: 8613989Abstract: A laser induced thermal imaging (LITI) apparatus and a method of making an electronic device using the same are disclosed. The LITI apparatus includes a chamber, a substrate support, a contact frame, and a laser source or oscillator. The LITI apparatus transfers a transferable layer from a film donor device onto a surface of an intermediate electronic device. The LITI apparatus uses a magnetic force to provide a close contact between the transferable layer and the surface of the intermediate device. The magnetic force is generated by magnetic materials formed in two components of the LITI apparatus that are spaced apart interposing transferable layer and the surface of the intermediate device. Magnets or magnetic materials are formed in the two following components of the LITI apparatus: 1) the intermediate device and the film donor device; 2) the intermediate device and the contact frame; 3) the substrate support and the film donor device; or 4) the substrate support and the contact frame.Type: GrantFiled: August 28, 2006Date of Patent: December 24, 2013Assignee: Samsung Display Co., Ltd.Inventors: Tae Min Kang, Jin Soo Kim, Mu Hyun Kim, Sun Hoe Kim, Noh Min Kwak, Sang Bong Lee, Seong Taek Lee, Seung Hyun Lee, Sok Won Noh, Jin Wook Seong, Myung Won Song, Yeun Joo Sung, Byeong Wook Yoo
