Latest Patents

Among his latest patents is a non-volatile memory device and operation method. This invention provides a non-volatile memory device that includes a source region, a drain region, a channel region, a floating gate, an enhance hot carrier injection gate, and an erasing gate. The floating gate is strategically placed on the channel region and the source region, with a first dielectric layer in between. The enhance hot carrier injection gate, which has an L-shaped cross-section, is positioned on the floating gate and the substrate. Additionally, a second dielectric layer is situated between the enhance hot carrier injection gate and the floating gate, while a fourth dielectric layer is placed between the enhance hot carrier injection gate and the substrate. The erasing gate is located on the drain region, with a third dielectric layer in between the erasing gate and the substrate.

Another notable patent is related to a composite impurity scheme for memory technologies. This integrated circuit features a memory array that includes diffusion bit lines with composite impurity profiles in a substrate. A plurality of word lines overlies channel regions in the substrate between the diffusion bit lines, with data storage structures such as floating gate structures or dielectric charge trapping structures at the cross-points. The composite impurity diffusion bit lines provide source and drain terminals on opposing sides of the channel regions, ensuring high conductivity, good depth, and steep doping profiles, even with channel region critical dimensions below 50 nanometers.
