A multilayer contact is shown having two superimposed conductive layers (14, 16) separated by a barrier layer (15) a first contact (11) extends through the upper conductive layer (14) to the lower conductive layer (16). A second contact (21, 30) separated from the first contact (11) extends to the upper conductive layer (14). A Schottky contact (18, 19) arranged between both contacts (11; 21, 30) on the surface of the upper conductive layer (14) establishes a depletion region (19) within the upper conductive layer (14). Said depletion region (19) electrically controls the current flow path between both contacts (11; 21, 30). |
