Latest Patents

One of his latest patents is the "Lead-free high-insulating ceramic coating zinc oxide arrester valve and preparation method thereof." This invention discloses a lead-free insulating ceramic coating zinc oxide arrester valve and a method for its manufacturing. The method involves preparing an initial powder from specific starting materials, including ZnO, Bi2O3, Co3O4, Mn3O4, Sb2O3, NiO, and SiO2. The process includes mixing the initial powder with deionized water, milling, drying, and pulverizing the mixture to create a ceramic coating slurry. This slurry is then applied to a green body, followed by heating and debinding to form a resistor element, ultimately resulting in a zinc oxide surge arrester valve block with a lead-free insulating ceramic coating.

Another significant patent is the "Reliability test structure for multilevel interconnect." This invention relates to structures and methods that allow for testing stress-induced electromigration in multiple interconnect metallization layers. The testing structure comprises segments of different metal layers through via structures, with nodes designed to receive force and sense voltages. This setup enables rapid and precise detection of stress-induced migration in each metal layer.
