Latest Patents
One of Peng Liu's notable patents is the "Method for Forming High Aspect Ratio Patterning Structure." This invention outlines a systematic approach to create high aspect ratio patterns on semiconductor substrates. It involves forming a dielectric film ashing stop layer, a first photoresist layer, a first hard mask layer, and a second photoresist layer sequentially. A second hard mask layer, which possesses a high etch selectivity ratio with the first photoresist layer, is applied through a low-temperature chemical vapor deposition process. This method effectively mitigates issues related to plasma bombardment and enhances the distribution of implanted ions, ensuring that the patterns meet the required specifications.
In addition, Liu developed a "Therapeutic Cryoablation System." This innovative system incorporates a gas source that provides nitrogen gas at room temperature and constant set pressure, alongside a liquid generator that transforms the working gas into a cryogen fluid. A catheter connected to the liquid generator delivers this cryogen through a distal section equipped with a freezing element, enhancing treatment capabilities with the inclusion of a balloon positioned adjacent to this section.
