With a total of 3 patents to his name, his work focuses on developing advanced materials and methods that enhance the production processes in these industries.
Latest Patents
Trichur's latest patents include innovative solutions such as acid-etch resistant protective coatings. These new compositions and methods are designed to serve as protective layers during the production of semiconductor and MEMS devices. The compositions consist of a cycloolefin copolymer that is either dispersed or dissolved in a solvent system. This technology allows for the formation of layers that effectively protect substrates during acid etching and other processing tasks. The protective layer can be either photosensitive or non-photosensitive and can be utilized with or without a primer layer beneath it. Preferred primer layers consist of a basic polymer in a solvent system.
Another notable patent is a device for coating the outer edge of a substrate during microelectronics manufacturing. This invention introduces new baffles and methods for their use. The baffles are designed with a body that has an edge wall, which directs the flow of a composition against the edge of a substrate, such as a silicon wafer. The edge wall features a vertical surface, a curved sidewall, and a lip, and is preferably annular in shape, made from a synthetic resinous composition rather than metal. The methods involve positioning the baffle adjacent to a substrate during a spin coating process, ensuring that the composition covers the edges and a portion of the back side of the substrate.
