Abstract
A semiconductor switching device () is formed on a semiconductor substrate () having a trench () formed on one of its surfaces (). A control electrode () activates a wall of the trench to form a conduction channel (). A first conduction electrode () is disposed on the semiconductor substrate to have a first doped region () for receiving a current and a second doped region () for routing the current to the conduction channel.
