Latest Patents
One of his latest patents is titled "Semiconductor structure including a ferroelectric transistor and method for the formation thereof." This patent describes a method that involves providing a semiconductor structure with a first transistor region, a second transistor region, and a silicon dioxide layer on both regions. A layer of high-k dielectric material is deposited on the silicon dioxide layer, followed by the formation of a layer of first metal over the second transistor region. This layer does not cover the first transistor region. Afterward, a layer of second metal is deposited over both transistor regions, and a first annealing process is performed. This process initiates a scavenging reaction between the second metal and silicon dioxide, leading to the formation of a ferroelectric transistor dielectric over the first transistor region.
Another illustrative patent by Seo also focuses on a semiconductor structure that includes a substrate with a logic transistor region, a ferroelectric transistor region, and an input/output transistor region. The logic transistor features a gate dielectric and a gate electrode, while the input/output transistor has a thicker gate dielectric compared to the logic transistor. The ferroelectric transistor is equipped with a ferroelectric dielectric arranged between its region and the gate electrode.
