Abstract
실시예에 따른 단결정 잉곳의 제조방법은 종자결정을 융액에 디핑하는 단계;상기 디핑 후 숄더링 공정을 진행하는 단계; 상기 숄더링 공정후 바디공정을 진행하는 단계; 및 상기 숄더링 공정 후 테일링 공정을 진행하는 단계;를 포함하는 고휘발성 원소가 도핑되는 단결정의 제조방법에 있어서, 상기 단결정의 바디공정 후반부의 최저 비저항을 12 mΩ이상으로 제어할 수 있다.
Description
도 2는 실시예에 따른 단결정 잉곳의 제조방법에서 바디공정에 따른 비저항 예시도.
도 3은 실시예에 따른 단결정 잉곳의 제조방법에서 바디공정에 따른 압력 변화 예시도.
Claims (5)
- 종자결정을 융액에 디핑하는 단계;
