    摘要: a A MOS (metal oxide semiconductor) transistor with a trench-type gate is fabricated with a channel stopping region for forming an asymmetric channel region for reducing short channel effects. For example in fabricating an N-channel MOS transistor, a gate structure is formed within a trench that is within a P-well. A channel stopping region with a P-type dopant is formed to a first side of the trench to completely contain an N-type source junction therein. An N-type drain junction is formed within a LDD region to a second side of the trench, thus forming the asymmetric channel region.

    摘要: A recess gate-type semiconductor device includes a gate electrode having a recessed portion at least partially covering a recess trench in an active region, and source/drain regions disposed in the active region that are separated by the gate electrode. The recess trench is separated from sidewalls of a device isolation region in a first direction and contacts sidewalls of the device isolation region in a second direction. The width of the recess trench of the active region in the second direction may be greater than the width of the source/drain regions in the second direction, and the recessed portion of the gate electrode may have tabs protruding in the first direction at its corners. Therefore, the semiconductor device has excellent junction leakage current and excellent refresh characteristics.

    摘要: In a method of manufacturing a semiconductor device, a first trench is formed in a first region of a substrate and a second trench is formed in a second region of the substrate different from the first region. A depth of the first trench is less than that of the second trench. An insulation layer is formed in the second trench, so that semiconductor structures in the first trench are electrically isolated, and a conductive layer fills the first trench and extends above the first trench.
