The method includes the steps of forming an anodized layer that has a thickness greater than a desired thickness, and forming an electrically conductive layer on the anodized layer. The method further includes the steps of removing the conductive layer in a selected area to expose the anodized layer, and removing the exposed anodized layer until the anodized layer in the exposed area has the desired thickness.
