Title: Gi Ra Yi: Innovator in Chemical Mechanical Polishing
Introduction
Gi Ra Yi is a prominent inventor based in Daejeon, South Korea. He has made significant contributions to the field of chemical mechanical polishing (CMP) with a total of 5 patents to his name. His work focuses on enhancing the efficiency and selectivity of polishing processes, which are crucial in various manufacturing applications.
Latest Patents
One of Gi Ra Yi's latest patents involves an adjuvant for controlling polishing selectivity and a chemical mechanical polishing slurry comprising the same. This invention discloses an adjuvant designed for simultaneous polishing of cationically charged materials and anionically charged materials. The adjuvant consists of a polyelectrolyte salt that includes a mixture of a linear polyelectrolyte with a weight average molecular weight ranging from 2,000 to 50,000, combined with a graft type polyelectrolyte that has a weight average molecular weight between 1,000 and 20,000. This innovative combination allows for increased polishing selectivity compared to CMP slurries that utilize only the linear polyelectrolyte. By adjusting the ratio of the linear polyelectrolyte to the graft type polyelectrolyte, desired polishing selectivity can be achieved.
