Abstract
PURPOSE: To perform uniform etching treatment by holding substrates in an etching jig opposite to each other, providing impellers between the substrates and inducing alternating currents in an etching soln.
CONSTITUTION: Notches 2 are provided to an etching jig 5, and substrates 3 to be etched are set at equal intervals by disposing their faces opposite to each other. Impellers are provided between the substrates 3 and are oscillated to stir the etching soln. between the substrates 3, so that the always fresh soln. contacts the entire surface of the substrate 3. By the use of such jig, the reaction of etching is progressed uniformly, and the etching is applied uniformly on large sized substrates as well. With micropatterns, too, they are finished with good accuracy, and the quality and yield of etching are improved.
