    Abstract: A NAND-type flash memory device including select transistors with an impurity region for restraining punch-through is provided to prevent a non-selected string from being programmed by restraining short channel effect and hot carrier effect of a string select transistor and a ground select transistor using gate patterns. First and second impurity regions(69b,69s) are formed in a semiconductor substrate(51). First and second select gate patterns(SGP1,SGP2) are disposed on the semiconductor substrate between the first and second impurity regions, adjoining the first and second impurity regions. A plurality of cell gate patterns(WP1,WP2,WP3,WP4) are disposed between the first and the second select gate patterns. A first anti-punchthrough impurity region(67b) comes in contact with the first impurity regions, overlaying a first edge of a first select gate pattern adjacent to the first impurity region. A second anti-punchthrough impurity region(67s) comes in contact with a second impurity region, overlaying a first edge of a second select gate pattern adjacent to the second impurity region. The semiconductor substrate between the first and the second anti-punchthrough impurity regions has a uniform impurity density along a direction parallel with the surface of the semiconductor substrate. Each cell gate pattern can include a tunnel insulation layer, a floating gate, an intergate dielectric and a control gate electrode that are sequentially formed.

CONSTITUTION: An isolation layer(102) is formed on the first conductive type semiconductor substrate(101) for defining an active region. A dummy gate pattern is formed on the active region. An epitaxial layer(104) is formed at both sides of the dummy gate pattern on the active region. The second conductive type impurity diffusion layer(106) is formed in the epitaxial layer. A dummy gate groove(110) is formed by removing the dummy gate pattern for partially exposing the active region and the sidewalls of the epitaxial layer. A gate isolating layer(116) and a gate electrode layer are sequentially formed in the dummy gate groove. The gate electrode layer is polished until the gate isolating layer on the epitaxial layer is exposed. A gate electrode(117b) is formed by selectively patterning the gate electrode layer.

    Abstract: An improved track belt tire is constructed of a removable tread belt assembly mounted to the outer circumferential surface of an inflatable tire carcass. A unique track belt design restrains the track from expanding while simultaneously improving the secure mounting of the track to the carcass and providing improved penetration protection. Also, the improved track belt will maintain a flatter tread profile which in turn will improve tread life and durability.
