PROBLEM TO BE SOLVED: To provide a manufacturing method of an organic thin film transistor having a fine pattern form only by means of a printing method and having correctly positioned lower and upper electrodes self-alignedly opposing via an insulation film without using a photomask. SOLUTION: Since the lower electrode is used as the photomask to align in position with the upper electrode, no shift in position occurs even if the printing method is employed. Thus, a semiconductor device such as a flexible substrate using an organic semiconductor can be inexpensively formed by the printing method. COPYRIGHT: (C)2007,JPO&INPIT
