Abstract: The current disclosure describes techniques for individually selecting the number of channel strips for a device. The channel strips are selected by defining a three-dimensional active region that include a surface active area and a depth/height. Semiconductor strips in the active region are selected as channel strips. Semiconductor strips contained in the active region will be configured to be channel strips. Semiconductor strips not included in the active region are not selected as channel strips and are separated from source/drain structures by an auxiliary buffer layer.

Abstract: This disclosure provides a negative capacitance gate stack structure with a variable positive capacitor to implement a hysteresis free negative capacitance field effect transistors (NCFETs) with improved voltage gain. The gate stack structure provides an effective ferroelectric negative capacitor by using the combination of a ferroelectric negative capacitor and the variable positive capacitor with semiconductor material (such as polysilicon), resulting in the effective ferroelectric negative capacitor's being varied with an applied gate voltage. Our simulation results show that the NCFET with the variable positive capacitor can achieve not only a non-hysteretic ID-VG curve but also a better sub-threshold slope.

The device further includes a vertically recessed channel region between the second sidewall of the first semiconductor fin and a bottom of the vertical recess, source/drain (S/D) regions at opposite ends of the vertically recessed channel region, and a gate stack over the vertically recessed channel region.
