Abstract
An aluminum nitride sintered body contains 1 to 5% by weight of yttrium oxide (YO), 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.
