Abstract
A semiconductor device includes a substrate, a bottom semiconductor fin, at least one sidewall structure, a top semiconductor fin, and a gate structure. The bottom semiconductor fin is disposed on the substrate. The sidewall structure protrudes from the semiconductor fin. The top semiconductor fin is disposed on the bottom semiconductor fin. The top semiconductor fin includes a channel portion and at least one source/drain portion. The source/drain portion is disposed between the channel portion and the sidewall structure. The gate structure covers the channel portion of the top semiconductor fin.
