Abstract
An active device substrate includes a substrate, a first semiconductor device and a second semiconductor device. The first semiconductor device and the second semiconductor device are disposed above the substrate. The first semiconductor device includes a first gate, a first semiconductor layer, a first source and a first drain. A first gate dielectric structure is sandwiched between the first gate and the first semiconductor layer. The first gate dielectric structure includes a stack of a portion of a gate dielectric layer and a portion of a ferroelectric material layer. The second semiconductor device is electrically connected to the first semiconductor device and includes a second gate, a second semiconductor layer, a second source and a second drain. Another part of the ferroelectric material layer is sandwiched between the second gate and the second semiconductor layer.
