Abstract
A method of forming an insulator and electrode member is disclosed, in its preferred form, as including an insulator having a first face supporting a uniform height conductive layer. A plurality of first electrode members are formed in the conductive layer by etching away or otherwise forming an array of apertures therein. A plurality of second electrode members are simultaneously formed either by printing, screening or other similar approach forming conductive material within and laterally spaced from the array of apertures.
