  • Patent number: 8268657
    Abstract: 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.
