Latest Patents

Arun Kumar Nanda holds a patent titled "Rounded surface for the pad conditioner using high temperature brazing." This invention pertains to a polishing pad conditioner that is essential in the removal of slurry and semiconductor thin film build-up during the chemical and mechanical polishing (CMP) process. The conditioner features a convex lower surface that is covered by diamond crystals, which are bonded to the nickel alloy conditioner. This design minimizes friction between the pad and conditioner, allowing the slurry to reach the center of the conditioner. As a result, it provides a more uniform conditioning of the pad surface, leading to uniformly polished wafers and an increased pad life. The use of brazing to form a molecular bond between the diamond crystals and the nickel alloy ensures durability against the low pH slurry used in CMP.
