A semiconductor memory device includes a transistor having a channel region buried in a substrate and source/drain regions formed to provide low contact resistance. A field isolation structure is formed in the substrate to define active structures. The field isolation structure includes a gap-fill pattern, a first material layer surrounding the gap-fill pattern, and a second material layer surrounding at least a portion of the first material layer. Each active structure includes a first active pattern having a top surface located beneath the level of the top surface of the field isolation structure, and a second active pattern disposed on the first active pattern and whose top is located above the level of the top surface of the field isolation structure.

A vertical type integrated circuit device includes a substrate and a pillar vertically protruding from the substrate. The pillar includes a lower impurity region and an upper impurity region therein and a vertical channel region therebetween. A portion of the pillar including the lower impurity region therein includes a mesa laterally extending therefrom. The device further includes a first conductive line extending on a first sidewall of the pillar and electrically contacting the lower impurity region, and a second conductive line extending on a second sidewall of the pillar adjacent the vertical channel region. The second conductive line extends in a direction perpendicular to the first conductive line and is spaced apart from the mesa. Related devices and methods of fabrication are also discussed.

摘要:
A method for decreasing a number of individual entries in a database of user-created records which describe a single item by: receiving a plurality of user-created records, each of said records comprising at least a descriptive string; placing individual ones of the plurality of user-created records having a sufficiently similar descriptive string into one of a plurality of first groups; hashing the descriptive string of each of the plurality of first groups in order to place two or more groups into a single bin; performing a pair-wise comparison of the descriptive strings of the two or more groups in each bin; and when the comparison of the descriptive strings of the two or more groups in a bin results in a distance below a first threshold, merging the two or more groups into a combined group.

A recessed transistor and a method of manufacturing the same are provided. The recessed transistor may include a substrate, an active pin, a gate pattern and source and drain regions. The substrate may include an isolation layer that establishes an active region and a field region of the substrate. The substrate may include a recessed structure having an upper recess formed in the active region and a lower recess in communication with the upper recess. An active pin may be formed in a region between side surfaces of the isolation layer and the lower recess and an interface between the active region and the field region. The gate pattern may include a gate insulation layer formed on an inner surface of the recessed structure and a gate electrode formed on the gate insulation layer in the recessed structure. The source/drain regions may be formed adjacent to the active region and the gate electrode.
