Latest Patents

One of her latest patents is titled "Inverted top-tier FET for multi-tier gate-on-gate 3-dimension integration (3Di)." This patent describes a multi-tier semiconductor structure that includes a first semiconductor device tier with first semiconductor devices. A first signal wiring structure is formed over and electrically connected to this tier. An insulator layer is then created over the first signal wiring structure, followed by a second semiconductor device tier that includes second semiconductor devices. A second signal wiring structure is also formed over the second semiconductor device tier, with an inter-tier via connecting the two tiers vertically through the insulator layer. This innovative design allows for monolithic formation of the semiconductor device tiers and inter-tier connections.

Another notable patent is the "Interdigitated device stack." This invention features a semiconductor device that includes a first pair of transistors positioned over a substrate. The first pair consists of a first transistor with a first gate structure and a second transistor with a second gate structure stacked over the first. A second pair of transistors is then stacked over the first pair, creating a vertical stack that is perpendicular to the substrate's working surface. This design enhances the efficiency and performance of semiconductor devices.
