Patent ID: 7704666

Claim:
A laser induced thermal imaging apparatus comprising: a chamber configured to contain a donor film and a substrate during a process for laminating the donor film on the substrate; a substrate stage having a first electromagnet, the substrate stage being in the chamber and configured to support the substrate; an adhesion frame having a second electromagnet and being in the chamber, the adhesion frame having an opening corresponding to a portion of the donor film to be laminated on the substrate, the adhesion frame and the substrate stage being configured to receive the donor film and the substrate between the substrate stage and the adhesion frame and configured to closely adhere the donor film and the substrate to each other utilizing a magnetic force formed between the first electromagnet and the second electromagnet; a laser oscillator configured to apply a laser output to the donor film through the opening of the adhesion frame; and an elevating drive unit coupled to the adhesion frame and configured to control both upward and downward movements of the adhesion frame and an adhesion strength between the donor film and the substrate utilizing the magnetic force formed between the first electromagnet and the second electromagnet.
