  • Publication number: 20110237037
    Abstract: In methods of manufacturing a recessed channel array transistor, a recess may be formed in an active region of a substrate. A plasma oxidation process may be performed on the substrate to form a preliminary gate oxide layer on an inner surface of the recess and an upper surface of the substrate. Moistures may be absorbed in a surface of the preliminary gate oxide layer to form a gate oxide layer. A gate electrode may be formed on the gate oxide layer to fill up the recess. Source/drain regions may be formed in an upper surface of the substrate at both sides of the gate electrode. Thus, the oxide layer may have a uniform thickness distribution and a dense structure.
