The invention relates to a quick template-free patterned electrode manufacturing method comprising the following steps: a light spot pattern is made in a computer; the pattern is projected on a chip through a projector to form a light spot; a signal generator generates an alternating-current signal to electrify the chip; and under the double action of the light spot and electrification, a metal electrode is formed on a photosensitive material base in the chip within a set period of time. According to the invention, based on the fact that metal ions can be reduced and absorbed on the surface of a virtual electrode, the shape of a metal deposition area can be controlled by controlling the shape of the light spot shining on an amorphous silicon layer, so as to manufacture a variety of patterns. By using the micro pattern manufacturing method, no physical template is needed, and a needed circuit can be obtained by designing the light spot directly according to the needed circuit structure and shape.
