Latest Patents

One of her latest patents is titled "Semiconductor device and manufacturing method thereof." This invention involves the formation of a silicon oxide film that covers a polysilicon plug. A bowing shaped hole is created, and a barrier metal along with a metal film is formed, which undergoes prescribed anisotropic etching. This method addresses the RIE-lag effect, ensuring that the etch rate of the barrier metal is controlled, thus preventing the exposure of the polysilicon plug's surface. This results in a semiconductor device that guarantees a reliable electrical connection of metal interconnections.

Another notable patent is "Semiconductor device having an improved contact structure and a manufacturing method thereof." This invention describes a method for forming a contact hole without damaging the etching stopper film or degrading electric characteristics. This is achieved through a self-alignment method, where an interlayer oxide film is etched using plasma etching with a specific gas mixture. This innovative approach allows for the tapering of the shoulder of the silicon nitride film, enhancing the overall performance of the semiconductor device.
