  • Ceramic wafer and the manufacturing method thereof
    Patent number: 10497638
    Abstract: A method of producing ceramic wafer includes a forming step and processing step. The processing step includes forming positioning notch or positioning, flat edge and edge profile, which avoids the ceramic wafers to have processing defect during cutting, grinding, and polishing, for increasing yield. The ceramic particles for producing ceramic wafer include nitride ceramic powder, oxide ceramic powder, and nitride ceramic powder. The ceramic wafer has low dielectric constant, insulation, and excellent heat dissipation, which can be applied for the need of semiconductor process, producing electric product and semiconductor equipment.
    Type: Grant
    Filed: November 16, 2016
    Date of Patent: December 3, 2019
    Assignee: HONG CHUANG APPLIED TECHNOLOGY CO., LTD.
