    Abstract: An integrated circuit includes a fin active region protruding from a substrate, a plurality of semiconductor patterns on an upper surface of the fin active region, a gate electrode that surrounds the plurality of semiconductor patterns and includes a main gate part on an uppermost one of the plurality of semiconductor patterns and sub gate parts between the plurality of semiconductor patterns, a spacer structure on a sidewall of the main gate part, and a source/drain region at a side of the gate electrode. The source/drain region is connected to the plurality of semiconductor patterns and contacts a bottom surface of the spacer structure. A top portion of the uppermost semiconductor pattern has a first width. A bottom portion of the uppermost semiconductor pattern has a second width smaller than the first width.

    Abstract: A semiconductor device includes a channel pattern including a first semiconductor pattern and a second semiconductor pattern, which are sequentially stacked on a substrate, and a gate electrode that extends in a first direction and crosses the channel pattern. The gate electrode includes a first portion interposed between the substrate and the first semiconductor pattern and a second portion interposed between the first and second semiconductor patterns. A maximum width in a second direction of the first portion is greater than a maximum width in the second direction of the second portion, and a maximum length in the second direction of the second semiconductor pattern is less than a maximum length in the second direction of the first semiconductor pattern.

    Abstract: A semiconductor memory device includes a stack structure including gate electrodes vertically stacked on a substrate and a vertical channel part penetrating the gate electrodes, a bit line connected to the vertical channel part, and a plurality of conductive lines connected to the gate electrodes on the stack structure. The conductive lines form a plurality of stacked layers and include first conductive lines and second conductive lines. The number of the first conductive lines disposed at a first level from the substrate is different from the number of the second conductive lines disposed at a second level from the substrate. The first level is different from the second level.
