ABSTRACT:
In a semiconductor substrate of a first conductivity type fixed at a predetermined potential are formed a plurality of resistive regions of a second conductivity type. The resistive regions are connected in series between first and second potential supply terminals, through equally divided potential taking-out electrodes formed on the substrate. The resistive regions are so formed as to be progressively decreased in length in the order that the potential difference between the resistive region and the substrate increases to cause the resistive regions to have the substantially equal resistance values.
