A method of etching an amorphous silicon layer includes providing a substrate with an amorphous silicon layer formed thereon into an atmospheric pressure plasma etching device, providing a plasma generation gas and etching gas to a plasma generator of the atmospheric pressure plasma etching device and generating an atmospheric pressure plasma gas between two electrodes provided in the plasma generator in which the two electrodes face each other. The method further includes repeatedly passing the substrate through the plasma generator at a predetermined speed, thereby etching the amorphous silicon layer on the substrate by using the atmospheric pressure plasma gas generated from the plasma generator.
