Abstract: By locally heating or cooling a substrate in an etching process, temperature unevenness is controlled, and convection currents of an etching liquid are restricted simultaneously. By setting the etching temperature low in an initial stage of the etching process and increasing it in a final stage, uniform and quick etching is possible. In a drop etching method, generation of bubbles can be prevented to ensure uniform etching by providing gas release openings in a member opposed to the substrate.
