  • Patent number: 6737303
    Abstract: A process for forming an organic semiconducting layer having molecular alignment. First, a photoalignment organic layer is formed on a substrate or A dielectric layer. Next, the photoalignment organic layer is irradiated by polarized light through a mask, such that the photoalignment organic layer becomes an orientation layer having molecular alignment. Finally, an organic semiconducting layer is formed on the orientation layer, such that the organic semiconducting layer aligns according to the alignment of the orientation layer to exhibit molecular alignment. The present invention can form an organic semiconducting layer with different molecular alignments in different regions over the same substrate by means of polarized light exposure through a mask.
