Classification: CPC H | IPC H

Claim 4:
5. A vertical field-effect transistor (VFET) device comprising:
a substrate;
at least one single-fin VFET formed on the substrate, and each of the at least one single-fin VFET comprising a fin structure and a gate structure surrounding the fin structure, the fin structure forming a channel for current flow in a vertical direction;
at least one multi-fin VFET formed on the same substrate, each of the at least one multi-fin VFET comprising a plurality of fin structures and a connected gate structure surrounding the fin structures; and
an isolation structure between a single-fin VFET and a neighboring multi-fin VFET to electrically disconnect the gate structure of the single-fin VFET and the connected gate structure of the neighboring multi-fin VFET,
wherein the connected gate structure is formed in a space between the neighboring two fin structures among the plurality of fin structures,
wherein a horizontal width of a fin structure of the multi-fin VFET is smaller than a horizontal width of the fin structure of the single-fin VFET.
