Abstract
A method of reducing random, processing-induced timing variations in a field effect transistor device includes providing a semiconductor substrate having an active area, and forming a transistor having a gate over a portion of the active area, the gate having a first leg and a second leg. In a further aspect, a method of improving the timing skew of critically-matched circuits is presented. In a still further aspect of the invention, a field effect transistor and an integrated circuit device that can be used to improve timing robustness in the presence of random fabrication- or process-induced variations are presented.
