책소개

종합적인 반도체 제조업체에서는 이미 패키지와 테스트에 관련된 실무 전문성 있는 책자를 2020년에 발간한 바 있으며 본 책자는 그 후속편이라 할 수 있겠습니다.
이 책자가 반도체업에 종사하는 모든 분들께 도움이 될 것으로 생각하며 특히 메모리 반도체인 DRAM과 NAND의 기본적인 이해 및 FabFabrication,
반도체 공장의 제조공정과 각종 장비에 대한 궁금증 또는 필요성이 있는 직접 관련 업무의 종사자분들, 반도체 산업의 기반이라 할 수있는 재료, 부품, 장비업에 종사하시는 분들,
그리고 교육 현장에서 학생들을 가르치시는 선생님들과 미래의 반도체 세계최고 전문가를 꿈꾸는 대한민국의 많은 희망들께 도움이 될 것으로 기대합니다.
다만 한 가지 아쉬운 점은 산업 보안 등의 이유로 저자들이 담고자 했던 내용들을 온전히 담지 못한것이며, 이에 대해서는 독자 여러분들의 넓은 이해를 구하고자 합니다.
