Method for making large area domain organic semiconductor crystal film and large area domain organic semiconductor crystal film

摘要

PROBLEM TO BE SOLVED: To provide a creation method of a large area domain organic semiconductor crystal film capable of forming a pattern in a desired position and to provide a large area domain organic semiconductor crystal film.SOLUTION: The creation method of a large area domain organic semiconductor crystal film includes; using a substrate for crystal growth 11 having a seed crystal part 21 and a crystal growth part 22 connected to the seed crystal part 21; coating and drying an organic semiconductor solution onto the seed crystal part 21 to produce a seed crystal; and growing the seed crystal at the crystal growth part 22 to produce a large area domain organic semiconductor crystal film 41.
