  • Patent number: 11769797
    Abstract: A nanosheet semiconductor device and fabrication method are described for integrating the fabrication of nanosheet transistors (71) and capacitors/sensors (72) in a single nanosheet process flow by forming separate transistor and capacitor/sensor stacks (12A-16A, 12B-16B) which are selectively processed to form gate electrode structures (68A-C) which replace remnant SiGe sandwich layers in the transistor stack, to form silicon fixed electrodes using silicon nanosheets (13C, 15C) on a first side of the capacitor/sensor stack, and to form SiGe fixed electrodes using SiGe nanosheets (12C, 14C, 16C) from the middle of remnant SiGe sandwich layers in the capacitor/sensor stack (e.g., 16-2) which are separated from the silicon fixed electrodes by selectively removing top and bottom SiGe nanosheets (e.g., 16-1, 16-3) from the remnant SiGe sandwich layers in the capacitor/sensor stack.

  • Patent number: 11616506
    Abstract: A circuit includes a P-channel transistor formed in a P-well and an N-channel transistor formed in an N-well. The first P-channel transistor has a control electrode connected to the P-well. The N-channel transistor is coupled in series with the P-channel transistor and has a control electrode connected to the N-well. Connecting the control electrodes of the P-channel and N-channel transistors to respective P-well and N-well effectively reduces crowbar current in the circuit.
