ABSTRACT:
A method of fabricating a donor substrate for a laser induced thermal imaging (LITI) process. A base substrate is prepared. A light-to-heat conversion layer is formed on the base substrate. A buffer layer is formed on the light-to-heat conversion layer. The surface roughness of the buffer layer is increased by treating the surface of the buffer layer. A transfer layer is formed on the surface-treated buffer layer. By using the donor substrate, a patterning process can be performed better during the fabrication of the OLED.
