Abstract

An asymmetric field-effect transistor having different gate-to-source and gate-to-drain overlaps allows lower parasitic capacitance on the drain side of the device and lower resistance on the source side. Source and drain regions having different configurations can be formed simultaneously using the same precursor materials.
