US Patent 12094984 Semiconductor device

A semiconductor device includes a non-volatile memory (NVM) cell. The NVM cell includes a semiconductor wire disposed over an insulating layer disposed on a substrate. The NVM cell includes a select transistor and a control transistor. The select transistor includes a gate dielectric layer disposed around the semiconductor wire and a select gate electrode disposed on the gate dielectric layer. The control transistor includes a stacked dielectric layer disposed around the semiconductor wire and a control gate electrode disposed on the stacked dielectric layer. The stacked dielectric layer includes a charge trapping layer. The select gate electrode is disposed adjacent to the control gate electrode with the stacked dielectric layer interposed therebetween.
