  • ALUMINUM NITRIDE SINTERED BODY AND MEMBER FOR SEMICONDUCTOR MANUFACUTING APPARATUS COMPRISING SAME
    Publication number: 20230024625
    Abstract: An aluminum nitride sintered body contains 1 to 5% by weight of yttrium oxide (Y2O3), 10 to 100 ppm by weight of titanium (Ti), and the balance being aluminum nitride (AlN). Accordingly, a volume resistance value and thermal conductivity at a high temperature are improved, and the generation of impurities during a semiconductor manufacturing process can be suppressed.
    Type: Application
    Filed: October 5, 2022
    Publication date: January 26, 2023
    Inventors: Je Ho CHAE, Hyo Sung PARK, Duck Won AHN, Tae Hee KANG
