ABSTRACT:
A varactor or mixer diode comprises a mesa shaped semiconductor element having a p-n junction barrier layer or retifying junction on its upper face and a substrate contact on its opposite face, the substrate contact extending over the side faces of the semiconductor element and ending at a small spacing from the barrier layer or junction.
