With a total of 6 patents to his name, Wu's work has had a substantial impact on the industry.

Latest Patents

One of Wu's latest patents is a method of forming semicrown-shaped stacked capacitors for dynamic random access memory (DRAM) devices. This innovative method involves the sequential formation of a first insulating layer, a second insulating etch-stop layer, and a high-etch-rate third insulating layer on a substrate over memory cell areas containing field-effect transistors (FETs). The process includes etching recesses in the insulating layers for bottom electrodes, aligning them over device areas, and plasma etching node contact openings to connect with the source/drain areas. A first polysilicon layer is then deposited to create node contacts and bottom electrodes. The use of a high-etch-rate fourth insulating layer fills the recesses, and both the fourth insulating layer and the first polysilicon layer are etched or polished back to form an array of bottom electrodes with oxide plugs. The final structure includes a thin dielectric layer and a patterned second polysilicon layer for top electrodes, enhancing the mechanical stability and photolithographic process window.

Another notable patent is for an offset dual gate thin film field effect transistor. This invention features a thin polycrystalline silicon layer as the channel region, with a lower gate electrode beneath the silicon layer and an upper gate electrode offset above it. The design includes gate dielectric layers between the electrodes and the silicon layer, optimizing the transistor's performance.
