摘要： A voltage divider with at least two intermediate taps of almost the same potential is formed in an integrated-circuit chip by diffusing P-type impurities into an N-type substrate along a narrow strip zone ending in enlarged terminal areas. The strip zone has at least two narrower transverse branches which form closely adjoining junctions with it and extend laterally in the same or in opposite directions. Upon application of a voltage difference across the strip zone by means of electrodes placed on the two terminal areas, output terminals in contact with the free ends of the branches remote from the strip zone and connected to high-resistance loads carry potentials substantially equal to those of the corresponding junctions.
