This device includes a selection transistor and a cell transistor including a cell gate insulation layer formed in a cell array area and a low-voltage MOS transistor having a low-voltage gate insulation layer and a high-voltage MOS transistor having a high-voltage gate insulation layer formed in a peripheral circuit area. The low-voltage gate insulation layer is thinner than the high-voltage gate insulation layer. The low-voltage gate insulation layer can also be thinner than the equivalent thickness of the cell gate insulation layer.

    摘要: Methods of forming a semiconductor device include forming a trench mask pattern on a semiconductor substrate having active regions and device isolation regions. A thermal oxidation process is performed using the trench mask pattern as a diffusion mask to form a thermal oxide layer defining a convex upper surface of the active regions. The thermal oxide layer and the semiconductor substrate are etched using the trench mask pattern as an etch mask to form trenches defining convex upper surfaces of the active regions. The trench mask pattern is removed to expose the convex upper surfaces of the active regions. Gate patterns are formed extending over the active regions.

    摘要: A NAND-type flash memory device for preventing punchthrough and a method for forming the same are provided. The NAND-type flash memory device includes a string selection transistor, a plurality of cell memory transistors, and a ground selection transistor being sequentially connected in series. The device further includes a bitline contact connected to a drain region of the string selection transistor, and a common source line connected to a source region of the ground selection transistor. Impurities are heavily doped to a drain-to-channel interface in the string selection transistor and a channel-to-source interface in the ground selection transistor, forming pockets for preventing punchthrough. The pockets are preferably formed using a tilted ion implantation using the vertical gate structures as masks.
