With a total of 4 patents to his name, Tsai's work is recognized for its innovative approaches to common challenges in the industry.

Latest Patents

One of Tsai's latest patents is titled "Reduction of Cu line damage by two-step CMP." This process involves performing chemical mechanical polishing (CMP) in two steps to minimize dishing effects. Initially, a hard pad is used to remove most of the copper until dishing effects begin to appear. Subsequently, a soft pad is employed to continue the CMP process until all copper is removed, except in the trenches. In another embodiment, CMP starts with a high-pressure pad that rotates slowly, transitioning to low pressure and high speed to achieve similar results.

Another significant patent is "Gap filling by two-step plating." This multi-step electrochemical method is designed for forming copper metallurgy on integrated circuits with high aspect ratio contact and via openings. The method ensures good coverage and gap filling capability while maintaining high production throughput. The process involves depositing copper in two stages, with an optional dwell period to replenish brighteners in the base region of high aspect ratio contacts or vias. This innovative approach avoids void formation and enhances the growth rate of copper from the bottom up.
