Abstract
Description
세정 방법 | 철 제거 효율d(%) |
UV/O3 a→ 원격 수소 플라즈마b | 98.4% |
원격 수소 플라즈마b→ UV/O3 a | 95.1% |
UV/O3 a→ 원격 수소 플라즈마b→ 열처리c | 99.8% |
UV/O3 a | 72% |
원격 수소 플라즈마b | 89% |
a: 반도체 표면을 25℃에서 UV/O330초 동안 노출한 것.b: 반도체 표면에 원격 수소 플라즈마를 26℃, 100 W에서 1분 동안 노출한 것.c: 반도체 표면을 600℃에서 3분 동안 열처리한 것.d: 제조예의 실리콘 기판 표면의 철 오염물 농도에 대한 제거 효율을 계산한 것. |
