ABSTRACT:
A glass wafer having high aspect ratio holes passing therethrough is provided with metal conductors in the holes as feedthroughs. First, the wafer is processed to line the holes with a thin electron-conducting layer of metal. Next, a layer of the same or different metal is applied over the first metal layer providing the requisite feedthrough electrical conductivity for each hole. Preferably, the glass contains lead oxide, the first metal layer is lead and the next layer is copper.
