Embodiments of the disclosure provide a transistor structure and methods to form the same. The transistor structure may include an active semiconductor region with a channel region between a first source/drain (S/D) region and a second S/D region. A polysilicon gate structure is above the channel region of the active semiconductor region. An overlying gate is positioned on the polysilicon gate structure. A horizontal width of the overlying gate is greater than a horizontal width of the polysilicon gate structure. The transistor structure includes a gate contact to the overlying gate.
