Abstract
An apparatus for electrochemical etching and an apparatus for electroplating are provided, wherein the apparatus for electrochemical etching includes an etching solution spraying head, a support, and a first and a second electrode. The first electrode is disposed inside the etching solution spraying head, and current is provided to an etching solution inside the etching solution spraying head by the first electrode. The support is disposed opposite to the etching solution spraying head. The second electrode is disposed on the support. When a substrate is placed on the second electrode, a first surface of the substrate is in electrical contact with the second electrode, and the etching solution sprayed from the etching solution spraying head can naturally flow through a second surface of the substrate and then flow off from the edges of the support.
