Abstract:
Fabricating a feedback field effect transistor includes receiving a semiconductor structure including a substrate, a first source/drain disposed on the substrate, a fin disposed on the first source/drain, and a hard mask disposed on a top surface of the fin. A bottom spacer is formed on a portion of the first source/drain. A first gate is formed upon the bottom spacer. A sacrificial spacer is formed upon the first gate, a gate spacer is formed on the first gate from the sacrificial spacer, and a second gate is formed on the gate spacer. The gate spacer is disposed between the first gate and the second gate. A top spacer is formed around portions of the second gate and hard mask, a recess is formed in the top spacer and hard mask, and a second source/drain is formed in the recess.

Claim (Index 1):
A method for fabricating a feedback field effect transistor, comprising:\n receiving a semiconductor structure including a substrate, a first source/drain disposed on the substrate, a fin disposed on the first source/drain, and a hard mask disposed on a top surface of the fin; forming a bottom spacer on a portion of the first source/drain; forming a first gate upon the bottom spacer; forming a sacrificial spacer upon the first gate; forming a gate spacer on the first gate from the sacrificial spacer; forming a second gate on the gate spacer, the gate spacer disposed between and in contact with the first gate and the second gate, wherein the first gate, the gate spacer, and the second gate form a portion of a dual-gate feedback loop mechanism of the feedback field effect transistor; forming a top spacer around portions of the second gate and hard mask; forming a recess in the top spacer and hard mask; and forming a second source/drain in the recess.
