Latest Patents

Masahi Shimoyama holds a patent for a unique plating method. This method is designed to achieve a desired dome height and includes several key steps. It involves preparing correlation data that illustrates the relationship between the proportion of dome height to bump height and the concentration of chloride ions. The process includes producing a plating solution with chloride ions at a concentration selected based on the desired dome height to bump height ratio. The concentration is maintained within a range of 100 mg/dm to 300 mg/dm. The substrate is then immersed in the plating solution, and an electric current is passed between an anode and the substrate, resulting in the formation of bumps on the substrate.
