Abstract

Thin organic film is coated on the laser absorbing layer. The organic material coated heat absorbing layer is closely contacted with the substrate. When the laser is incident on the heat absorbing layer, the absorbing layer is expanded and the organic film is transferred to the substrate. When the laser has Gaussian spatial profile, the profile of printed organic material becomes non-uniform. We tried several laser beam profile shaping methods to get a clean and sharp printing. The dependences of eliminated organic material profile from donor plate on the laser power, beam shaping method, and the layer thickness are also investigated.
