  • Publication number: 20200259018
    Abstract: Disclosed herein are field-effect transistors with asymmetric gate stacks. An example transistor includes a channel material and an asymmetric gate stack, provided over a portion of the channel material between source and drain (S/D) regions. The gate stack is asymmetric in that a thickness of a gate dielectric of a portion of the gate stack closer to one of the S/D regions is different from that of a portion of the gate stack closer to the other S/D region, and in that a work function (WF) material of a portion of the gate stack closer to one of the S/D regions is different from a WF material of a portion of the gate stack closer to the other S/D region. Transistors as described herein exploit asymmetry in the gate stacks to improve the transistor performance in terms of high breakdown voltage, high gain, and/or high output resistance.
