InactiveCN1661807AIncrease impurity concentrationGuaranteed withstand voltageConnection to earthConnection contact member materialBreakdown strengthSchottky barrier
The conventional Schottky barrier diode has a problem that the increase in leak current is evitable for realizing low VF due to the VF and IR characteristics of the Schottky barrier diode are in a trade-off relation. In the semiconductor device of this invention, pillar shaped p type semiconductor regions that reach an n+ type semiconductor substrate are provided in an n- type semiconductor layer, so that when a reverse voltage is applied, the part of the n- type semiconductor layer between the p type semiconductor regions is filled completely by a depletion layer expanding from the p type semiconductor region and in the horizontal direction of the substrate. In other words, the leakage of the leak current generated at the Schottky junction interface to the cathode side can be suppressed. Moreover, since the impurity concentration in the n- type semiconductor layer can be increased to the extent that the depletion layer expanding from the adjacent p type semiconductor regions can still pinch off, the low VF can be realized, and a predetermined breakdown strength can be secured as long as the depletion layer can pinch off.
