Abstract
An electroconductive support can include a layer that defines a cavity, and a conductive strand within the cavity of the layer. The conductive strand can have an upper surface within a central zone and a side zone, wherein the upper surface has a surface roughness within the central zone that is rougher than a surface roughness within the side zone. The electroconductive can further include an electroconductive layer and a passivation layer overlying the conductive strand. The relatively smoother upper surface within the side zone can allow the width of the passivation layer to be relatively narrow and still achieve acceptable leakage current. A method of forming the electroconductive support can be performed using a wet chemical technique to form the conductive strand while suppressing roughness along a side zone of the upper surface of the conductive strand.
