Abstract: 반도체 소재 배선에 절연부를 개스 플라즈마에 의해 부여할 때, 동일 소재를 보유하고, 세라믹 기재(基材)를 적층한 정전 척킹(chucking) 방식의 보유체로서, 플라즈마 내식성(耐食性)이 우수하고, 큰 외경이라도 각 부(部)의 치수 정밀도가 높은 보유체(정전 척)를 제공한다. 
     복수의 질화 알루미늄(AlN)계 세라믹스로 이루어지는 기재를 고융점 금속층과 접착층에 의해 적층한 반도체 제조용 보유체에 있어서, 특히 이 질화 알루미늄(AlN) 세라믹 기재가 3a족 원소의 화합물을 동원소로 환산하여 0.01∼1 중량 % 포함하고, 나머지부가 실질적으로 질화 알루미늄(AlN)으로 이루어지며, AlN 결정의 평균 입자 지름이 2∼5 μm인 것으로 한다.
