Abstract
A semiconductor assemblage of a super-trench Schottky barrier diode (STSBD) made up of an nsubstrate, an n-epilayer, trenches etched into the n-epilayer that have a width and a distance from the nsubstrate, mesa regions between the adjacent trenches having a width, a metal layer on the front side of the chip that is a Schottky contact and serves as an anode electrode, and a metal layer on the back side of the chip that is an ohmic contact and serves as a cathode electrode, wherein multiple Schottky contacts having a width or distance and a distance between the Schottky contacts, and between the Schottky contact as anode electrode and the first Schottky contact, are located on the trench wall.
