Abstract:
An integrated circuit (IC) including at least one combinational logic path. The features in the combinational logic path are self compensating for out-of-focus effects. In particular, field effect transistor (FET) gates may be iso-focally spaced such that the gate (critical dimension) may move with changing focus, but the gate length remains the same. Alternately, logic circuits in a path may self-compensate for focus effects on individual circuits.
