    Abstract: Vertical field-effect transistor (VFET) devices and methods of forming VFET devices are provided. The methods may include forming a preliminary VFET on a substrate. The preliminary VFET may include a bottom source/drain region on the substrate, a channel region on the bottom source/drain region, a top source/drain region on the channel region, a patterned sacrificial layer on a side surface of the channel region, and an insulating layer. The top source/drain region and the patterned sacrificial layer may be enclosed by the insulating layer. The methods may also include forming a contact opening extending through the insulating layer and exposing a portion of the patterned sacrificial layer, forming a cavity between the channel region and the insulating layer by removing the patterned sacrificial layer through the contact opening, and forming a gate electrode in the cavity.

    Abstract: A method of fabricating a semiconductor device is provided. A plurality of target patterns is formed on a substrate. The plurality of target patterns is extended in parallel to each other along a first direction. A first mask pattern extending in the first direction and including a plurality of first openings is formed. A second mask pattern extending in a second direction crossing the first direction and including a plurality of second openings is formed. Each second opening overlaps each first opening to form an overlapped opening region. A region of the plurality of target patterns is etched through the overlapped opening region using the first mask pattern and the second mask pattern as a etch mask. The region of the plurality of target patterns is overlapped with the overlapped opening region.
