Abstract:
A low-resistance gate transistor comprising:a gate oxide film formed on a semiconductor substrate; a gate formed on the gate oxide film; a first gate sidewall having a vertical pattern in contact with a side of the gate at both sides of the gate and a horizontal pattern formed on the gate and the gate oxide film extended from the vertical pattern; second gate sidewalls formed of a material having a resistivity lower than the gate, each of said second gate sidewalls having one side in contact with the vertical pattern of the first gate sidewall and a bottom in contact with the horizontal pattern of the first gate sidewall, and said second gate sidewalls each having a round surface, wherein a top surface of the second gate sidewalls is at a same height as or lower than a top surface of the first gate sidewall; an insulating layer on an entire surface including the gate and the first and second gate sidewalls; and source/drain regions in a surface of the semiconductor substrate on both sides of the gate.
