A Schottky diode includes an n+-substrate, an n-epilayer, trenches introduced into the n-epilayer, floating Schottky contacts being located on their side walls and on the entire trench bottom, mesa regions between the adjacent trenches, a metal layer on its back face, this metal layer being used as a cathode electrode, and an anode electrode on the front face of the Schottky diode having two metal layers, the first metal layer of which forms a Schottky contact and the second metal layer of which is situated below the first metal layer and also forms a Schottky contact. Preferably, these two Schottky contacts have different barrier heights.
