Patent ID: 8519433

Claim:
A semiconductor switching device, comprising: a) a substrate having deposited thereon a cathode disc, an anode and a gate of the semiconductor switching device; and b) a connection for electrically connecting the cathode disc and the gate of the semiconductor switching device to an external circuit unit, wherein c) the connection comprises: a cathode-gate connection unit having a coaxial structure including a gate conductor and a cathode conductor for electrically connecting the cathode and the gate of the semiconductor switching device to the external circuit unit, wherein the cathode conductor comprises a cathode connection terminal for connecting the cathode conductor to the cathode disc, and at least two cathode-gate connection units having a coaxial structure including a gate conductor and a cathode conductor for electrically connecting the cathode and the gate of the semiconductor switching device to the external circuit unit, wherein the at least two cathode-gate connection units are arranged symmetrically around the cathode disc.
