    摘要: A gate pattern is disclosed that includes a semiconductor substrate, a lower conductive pattern, an upper conductive pattern, and a sidewall conductive pattern. The lower conductive pattern is on the substrate. The insulating pattern is on the lower conductive pattern. The upper conductive pattern is on the insulating pattern opposite to the lower conductive pattern. The sidewall conductive pattern is on at least a portion of sidewalls of the upper conductive pattern and the lower conductive pattern. The sidewall conductive pattern electrically connects the upper conductive pattern and the lower conductive pattern. An upper edge portion of the lower conductive pattern may be recessed relative to a lower edge portion of the lower conductive pattern to define a ledge thereon. The sidewall conductive pattern may be directly on the ledge and sidewall of the recessed upper edge portion of the lower conductive pattern.

    摘要: A non-volatile memory device includes a tunneling insulating layer on a semiconductor substrate, a charge storage layer, a blocking insulating layer, and a gate electrode. The charge storage layer is on the tunnel insulating layer and has a smaller band gap than the tunnel insulating layer and has a greater band gap than the semiconductor substrate. The blocking insulating layer is on the charge storage layer and has a greater band gap than the charge storage layer and has a smaller band gap than the tunnel insulating layer. The gate electrode is on the blocking insulating layer.

    摘要: A semiconductor device (e.g., a non-volatile memory device) with improved data retention characteristics includes active regions that protrude above a top surface of a device isolation region. A tunneling insulating layer is formed on the active regions. Charge storage patterns (e.g., charge trap patterns) are formed so as to be spaced apart from each other. A blocking insulating layer and a gate are formed on the charge storage patterns.
