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.

Claim (Index 12):
An asymmetric field-effect transistor structure comprising:\n a plurality of parallel semiconductor fins, each of the semiconductor fins including sidewalls and a channel region; a gate electrode extending across the semiconductor fins, the gate electrode having a first side and a second side and being operatively associated with the channel regions of the semiconductor fins; a gate dielectric layer between the gate electrode and each of the channel regions; an electrically insulating, shallow trench isolation layer having a top surface, the semiconductor fins having bottom portions embedded within the shallow trench isolation layer; a recess extending within each of the semiconductor fins on the first side of the gate electrode, the semiconductor fins including unrecessed portions on the second side of the gate electrode; a plurality of embedded, epitaxial source regions on the semiconductor fins, each of the epitaxial source regions being doped and extending within one of the recesses and beneath the top surface of the shallow trench isolation layer; and a plurality of cladded, doped epitaxial drain regions on the sidewalls of the unrecessed portions of the semiconductor fins, none of the doped epitaxial drain regions extending beneath the top surface of the shallow trench isolation layer.
