Abstract:
1. An integrated circuit including a transistor, the transistor comprising: first and second source/drain regions formed in a semiconductor material and extending at least to a first depth with respect to a top surface of the semiconductor material; a channel region disposed between the first and second source/drain regions and comprising a fin-like portion including a ridge with a top side and two lateral sides in a cross-section perpendicular to a first direction defined by a line extending between the first and second source/drain regions; and a gate electrode disposed in a gate groove defined in a top surface of the semiconductor material between the first and second source/drain regions; wherein a top surface of the gate electrode is disposed between the top surface of the semiconductor material and the first depth; and wherein the gate electrode surrounds the ridge at the top side and the two lateral sides.
