Patent ID: 8277900

Claim:
A patterning method comprising: moving a nozzle from an unelevated position to an elevated position; moving the nozzle and a substrate relative to each other so as to apply a semiconductor coating liquid to a surface of said substrate, said nozzle being disposed on a lower side of said substrate and said substrate being faced down with the surface of said substrate including a recess-projection structure having a recessed portion and a projected portion being controlled in wettability so as thereby to apply said semiconductor coating liquid to the recessed portion of said substrate so as to form a uniform semiconductor coating layer such that an entire coating thickness of the semiconductor coating layer is substantially equal to an entire thickness of a material of the projected portion, wherein the semiconductor coating layer contacts the projected portion and wherein when the substrate is faced upwardly, an uppermost surface of the material of the projected portion is formed to be substantially flush with an uppermost surface of the uniform semiconductor coating layer and a lowermost surface of the material of the projected portion is formed to be substantially flush with a lowermost surface of the uniform semiconductor coating layer, said semiconductor coating liquid being applied as a liquid by capillarity; thereafter, drying said semiconductor coating liquid so as thereby to obtain a pattern including a dried semiconductor coating layer; forming an insulation layer having a uniform thickness on the uppermost side of the semiconductor coating layer and the uppermost side of the projected portion when the substrate is faced upwardly; and moving the nozzle from the elevated position to a lowered position.
