    Abstract: A vertical memory device includes gate electrode structures, channels, first to third division patterns, and a first support layer. The gate electrode structure includes gate electrodes stacked in a first direction, and extends in a second direction. The gate electrode structures are spaced apart from one another in a third direction. The first division pattern extends in the second direction between the gate electrode structures. The second and third division patterns are alternately disposed in the second direction between the gate electrode structures. The first support layer is on the gate electrode structures at substantially the same height as upper portions of the first and second division patterns, and contacts the upper portions of the first and second division patterns. The upper portions of the first and second division patterns are arranged in a zigzag pattern in the second direction in a plan view.

    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: 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.
