Latest Patents

Among Eric's latest innovations is the patent for "Simultaneous planarization of pole piece and coil materials for write head applications." This method addresses the challenge of achieving equal smoothness in a thin film magnetic head hardbaked resist structure that has low surface energy, in conjunction with other materials like copper and NiFe that possess higher surface energy. The process utilizes a specialized chemical mechanical polishing (CMP) slurry tailored to ensure an equal removal rate across different materials, resulting in enhanced performance for magnetic heads.

Another noteworthy patent is the "Method for shaping pole pieces of magnetic heads by chemical mechanical polishing." This invention improves the Ppole tip/yoke interface of thin film magnetic heads. By employing a CIP polishing step with a soft polishing pad and an acidic slurry, Eric’s technique refines the upper surface of the Ppole tip, creating a concave curved interface with the yoke, ultimately leading to improved magnetic performance.
