Abstract
A method of making a circuitized substrate. A conductive layer having a substantially planar upper surface is formed on and in direct mechanical contact with an upper surface of a substrate. A portion of the conductive layer is removed to form an interim side wall in the conductive layer. A layer of patternable material is formed on the substantially planar upper surface and on the interim side wall. A portion of the layer of patternable material on the conductive layer is removed to expose the interim side wall. A portion of the substantially planar upper surface is removed to form a side wall in the layer of patternable material. Portions of the interim side wall in the conductive layer are removed to form a second side wall and a bottom wall defined by the upper surface of the substrate. The second side wall is substantially perpendicular to the bottom wall.
