Abstract:
1. A method of enabling selective area plating on a substrate, the method comprising: forming a first electrically conductive layer over substantially all of the substrate; covering sections of the first electrically conductive layer with a mask such that the first electrically conductive layer has a masked portion and an unmasked portion; partially oxidizing the first electrically conductive layer in order to form a black oxide layer in a region of the first electrically conductive layer; and patterning the substrate in order to form a feature therein, the feature extending through the black oxide layer and the first electrically conductive layer; forming a second electrically conductive layer, the second electrically conductive layer forming only over the unmasked portion of the first electrically conductive layer; and removing the mask and the masked portion of the first electrically conductive layer.
