Abstract
We herein describe a gate controlled semiconductor device having a plurality of gate trenches, in which the plurality of gate trenches are laterally spaced from each other in a first dimension, current flows in a second dimension substantially transverse to the first dimension, and the plurality of gate trenches each extend in a third dimension of the device. A secondary trench extends in the first dimension of the device, and the secondary trench contacts each gate trench of the plurality of gate trenches at a plurality of intersection regions laterally spaced along the secondary trench.
