In a channel formed in one surface of a semiconductor substrate having a first conductivity, e.g. N type, a layer of material having a second conductivity type, e.g. P type boron, and a layer of relatively low resistance material such as Tungsten in contact with the first layer but insulated from the substrate. Second conductivity type tubs and the like can be formed adjacent the bus and in direct contact therewith through the first layer.
