Patent ID: 8057848

Claim:
A method for forming an organic semiconductor layer pattern, comprised of: preparing a donor substrate comprising: a base substrate; and a transfer layer formed on the base substrate, the transfer layer containing an organic semiconductor precursor having a thermally decomposable substituent, the organic semiconductor precursor forming pentacene when the thermally decomposable substituent of the organic semiconductor precursor is thermally decomposed by an application of an energy source, wherein, when the pentacene is formed the organic semiconductor precursor having a thermally decomposable substituent is at least one selected from the group consisting of compounds of formulae (3) through (5) where each of R 1 and R 2 is independently an alkyl group having 1 to 40 carbons, a cycloalkyl group having 4 to 40 carbons, an a 1 koxy group having 1 to 40 carbons, an aryl group having 6 to 40 carbons, an aryloxy group having 6 to 40 carbons, an alkenyl group having 2 to 40 carbons, an alkylaryl group having 7 to 40 carbons, an arylalkyl group having 7 to 40 carbons, an arylalkenyl group having 8 to 40 carbons, or an alkynyl group having 2 to 40 carbons; R 3 and R 4 are each independently an alkyl group having 4 to 40 carbons, a silyl group having 3 to 40 carbons, or a siloxyl group having 3 to 40 carbons; R is selected from the group consisting of the compounds represented by formulae (3) and (4); and positioning the donor substrate to contact a receptor substrate and transferring the transfer layer to the receptor substrate to form an organic semiconductor layer pattern upon application of the energy source.
