Claim:
1. A method of forming a semiconductor device, the method comprising: forming a first source/drain layer over a substrate; forming a channel layer over the first source/drain layer; forming a second source/drain layer over the channel layer; patterning the first source/drain layer, the channel layer, and the second source/drain layer to form a fin-shaped structure; forming a gate stack on a sidewall of the fin-shaped structure; and patterning the fin-shaped structure to expose a top surface of the first source/drain layer; and after the forming the gate stack, forming a dielectric layer over the first source/drain layer, the second source/drain layer, and the gate stack, the dielectric layer physically contacting the top surface of the first source/drain layer and a top surface of the second source/drain layer.
