    摘要: A semiconductor device having a buried gate line with a shaped gate trench and a method of fabricating the same are disclosed. The semiconductor device includes a trench isolation layer provided in a semiconductor substrate to define a multi-surfaced active region/channel. A gate line extending to the trench isolation layer fills a portion of the gate trench. The gate trench is formed with a series of depressions to accommodate peaks in the channel. The combination of depressions/peaks operate to increase the effective area of the channel, thereby enabling smaller channel semiconductor devices to be formed without increasing the width thereof.

The conductive plug wire pattern includes a recessed portion that exposes portions of opposing sidewalls of the trench, and an integral plug portion that protrudes from a surface of the recessed portion to provide an electrical connection to at least one other conductive wire pattern on a different level of metallization. A surface of the plug portion may protrude to a substantially same level as a surface of the substrate adjacent to and outside the trench, and the surface of the recessed portion may be below the surface of the substrate outside the trench. Related fabrication methods are also discussed.

    摘要: There are provided a semiconductor device having a vertical transistor and a method of fabricating the same. The method includes preparing a semiconductor substrate having a cell region and a peripheral circuit region. Island-shaped vertical gate structures two-dimensionally aligned along a row direction and a column direction are formed on the substrate of the cell region. Each of the vertical gate structures includes a semiconductor pillar and a gate electrode surrounding a center portion of the semiconductor pillar. A bit line separation trench is formed inside the semiconductor substrate below a gap region between the vertical gate structures, and a peripheral circuit trench confining a peripheral circuit active region is formed inside the semiconductor substrate of the peripheral circuit region. The bit line separation trench is formed in parallel with the column direction of the vertical gate structures. A bit line separation insulating layer and a peripheral circuit isolation layer are formed inside the bit line separation trench and the peripheral circuit trench, respectively.
