Abstract
PURPOSE: To eliminate the effect of bias resistance by providing a plurality of one conductivity type regions within a plurality of reverse conductivity type regions provided within a one conductivity type semiconductor substrate and using the PN junctions formed by these as a varactor device and the PN junctions of the reverse conductivity type regions and the substrate as a direct current blocking capacitor.
