CERAMIC, PROBE GUIDANCE COMPONENT, PROBE CARD, AND PACKAGE INSPECTING SOCKET
A ceramic contains, in mass percent: Si3N4: 20.0 to 60.0%, ZrO2: 25.0 to 70.0%, and one or more oxides selected from MgO, Y2O3, CeO2, CaO, HfO2, TiO2, Al2O3, SiO2, MoO3, CrO, CoO, ZnO, Ga2O3, Ta2O5, NiO, and V2O5: 5.0 to 15.0%. The ceramic has a coefficient of thermal expansion as high as that of silicon and an excellent mechanical strength, allows fine machining with high precision, and prevents particles from being produced.
