In the present circumstances, a film formation method of using spin
coating in a manufacturing process is heavily used. As increasing the
substrate size in future, the film formation method of using spin coating
becomes at a disadvantage in mass production since a mechanism for
rotating a large substrate becomes large, and there is many loss of
material solution or waste liquid. According to the present invention, in
a manufacturing process of a semiconductor device, a microscopic wiring
pattern can be realized by delivering selectively photosensitive
conductive material solution by droplet discharging, exposing selectively
to laser light or the like, and developing. The present invention can
reduce drastically costs since a patterning process can be shortened and
an amount of material in a process of forming a conductive pattern can be
reduced. Accordingly, the present invention can be applied to manufacture
a large substrate.
