The solubility and low processing temperatures of organic semiconductors enable fabrication of electronic devices using relatively simple printing technologies, and hold promise for realizing flexible plastic devices by environment‐friendly production methods at low cost. In particular, by effectively using the self‐assembling ability of molecules, production methods for organic semiconductor devices are expected to become more efficient in terms of energy and material consumption. We have developed two solution‐based methods for self‐organized formation of organic semiconductor crystals, including area selective nucleation of crystalline semiconductor films and direct formation of organic single crystals. These bottom‐up methods of device fabrication, wherein the intrinsic functionalities of molecules are utilized for spontaneous assembly, may become a core technology for future plastic electronics.
