Latest Patents

Han's latest patents include a method of manufacturing a semiconductor device. This method involves providing a substrate, forming a channel layer on the substrate, and creating a barrier layer on the channel layer. Additionally, a source and a drain are formed on the barrier layer, and a recess is created in the barrier layer. The recess has a bottom surface, and a portion of the barrier underneath it has a specific thickness. A first dielectric layer is formed to cover the bottom surface of the recess, followed by a charge trapping layer and a first ferroelectric material layer. A second dielectric layer and a second ferroelectric material layer are then formed, with a gate positioned over the second ferroelectric material layer.

Another patent by Han describes a semiconductor device that includes a substrate, a channel layer, a barrier layer, and a ferroelectric composite material layer. The channel layer and the barrier layer, which has a recess, are sequentially disposed on the substrate. The ferroelectric composite material layer consists of a first dielectric layer, a charge trapping layer, a first ferroelectric material layer, a second dielectric layer, and a second ferroelectric material layer, all positioned within the recess. The gate is placed on the ferroelectric composite material layer, while the source and drain are located on the barrier layer.
