    • A non-volatile semiconductor device includes a memory cell in a first area of a substrate, a low voltage transistor in a second area of the substrate, and a high voltage transistor in a third area of the substrate. The memory cell includes a tunnel insulation layer formed on the substrate, a charge trapping layer pattern formed on the tunnel insulation layer in the first area of the substrate, a blocking layer pattern formed on the charge trapping layer pattern and a control gate formed on the blocking layer pattern. The control gate has a width substantially smaller than a width of the blocking layer pattern and the width of the control gate is substantially smaller than a width of the charge trapping layer pattern. In addition, an offset is formed between the control gate and the blocking layer pattern such that a spacer is not formed on a sidewall of the control gate.

    • Some methods are directed to manufacturing charge trap-type non-volatile memory devices. An isolation layer pattern can be formed that extends in a first direction in a substrate. A recess unit is formed in the substrate by recessing an exposed surface of the substrate adjacent to the isolation layer pattern. A tunnel insulating layer and a charge trap layer are sequentially formed on the substrate. The tunnel insulating layer and the charge trap layer are patterned to form an isolated island-shaped tunnel insulating layer pattern and an isolated island-shaped charge trap layer pattern by etching defined regions of the substrate, the isolation layer pattern, the tunnel insulating layer, and the charge trap layer until a top surface of the charge trap layer that is disposed on a bottom surface of the recess unit is aligned with a top surface of the isolation layer pattern. A blocking insulating layer is formed that covers the charge trap layer pattern, the isolation layer pattern, and a defined region of the substrate interposed between the charge trap patterns. A gate electrode pattern is formed on the blocking insulating layer to face the charge trap layer pattern. This manufacturing process may reduce charge spreading between unit memory cells and/or may prevent/avoid reduction in the breakdown voltage of the blocking insulating layer.

    • According to example embodiments of inventive concepts, a method includes forming cell patterns and insulating interlayers between the cell patterns on the substrate. An upper insulating interlayer including initial and preliminary contact holes is formed on an uppermost cell pattern. A first reflection limiting layer pattern and a first photoresist layer pattern are formed for exposing a first preliminary contact hole while covering inlet portion of the initial and preliminary contact holes. A first etching process is performed on layers under the first preliminary contact hole to expose the cell pattern at a lower position than a bottom of the first preliminary contact hole. A partial removing process of sidewall portions of the first reflection limiting layer pattern and the first photoresist layer pattern and an etching process on exposed layers through bottom portions of the preliminary contact holes are repeated for forming contact holes having different depths.
