Abstract
In an embodiment, a method includes forming an adhesion promotion layer on at least portions of a conductive surface arranged on a Group III nitride-based semiconductor layer, applying a resist layer to the adhesion promotion layer such that regions of the conductive surface are uncovered by the adhesion promotion layer and the resist layer, applying by electroplating a conductive layer to the regions of the conductive surface uncovered by the adhesion promotion layer and the resist layer, and removing the resist layer and removing the adhesion promotion layer.
