Abstract
A trench-gated field effect transistor (FET) is formed as follows. Using one mask, a plurality of active gate trenches and at least one gate runner trench are defined and simultaneously formed in a silicon region such that (i) the at least one gate runner trench has a width greater than a width of each of the plurality of active gate trenches, and (ii) the plurality of active gate trenches are contiguous with the at least one gate runner trench.
