Latest Patents
One of his latest patents is titled "Crystal phase identification." This invention provides a method and apparatus for unambiguously identifying and determining the crystalline phase and crystalline characteristics of a sample. By utilizing an electron beam generator, such as a scanning electron microscope, the method obtains a backscattered electron Kikuchi pattern of a sample. It extracts crystallographic and composition data that is matched to database information, offering a quick and automatic method to identify crystalline phases.
Another significant patent is "Microstructure control of Al-Cu films for improved electromigration." This process focuses on forming Al-Cu conductive thin films with reduced electromigration failures, which is particularly useful in the metallization of integrated circuits. The improved formation process includes heat treatment or annealing of the thin film conductor at temperatures ranging from 200°C to 300°C for a duration between 10 minutes and 24 hours under a reducing atmosphere, such as 15% H₂ in N₂ by volume. This method enhances the electromigration behavior of aluminum by hindering aluminum diffusion along the grain boundaries.
