Abstract: A ceramic susceptor particularly with excellent volumetric resistance at high temperatures and thermal conductivity at room temperature compared to a typical ceramic susceptor and a method for manufacturing the same are disclosed. The ceramic susceptor is characterized by comprising alumina (Al2O3); and aluminum nitride (AlN), and not comprising a secondary phase including an aluminum oxynitride phase (AlON phase).

Abstract: Disclosed is a ceramic heater for a semiconductor manufacturing apparatus, the ceramic heater having volume resistivity especially at high temperature and thermal conductivity at room temperature that are superior to those of a normal ceramic heater for a semiconductor manufacturing apparatus. The ceramic heater for a semiconductor manufacturing apparatus includes a ceramic substrate including a) aluminum nitride (AIN), b) any one or more among magnesium oxide (MgO), alumina (Al2O3) and spinel (MgAl2O4), c) calcium oxide (CaO) and d) titanium dioxide (TiO2); and a resistive heating element.
