In plasma etching process, materials having higher corrosion resistance are required. We developed an advanced MgO-based ceramics with excellent corrosion resistance and high mechanical characteristics. Further, we also succeeded in lowering electric resistance to the order of 100 ohm centimeter without deterioration of its excellent corrosion resistance.
