Claims (4)
- (정정) 1회웨이퍼가 고정되는 진공회전척과; 상기 진공회전척 상부에 설치되는 코팅컵과; 코팅액을 분사하기 위한 코팅액 분사장치와; 상기 진공회전척과 웨이퍼의 중심을 정렬하기 위한 웨이퍼 정렬수단과; 웨이퍼 회전시 상기 코팅컵의 상부를 막아 밀페시키는 코팅컵 밀폐수단을 구비한 것을 특징으로 하는 웨이퍼 코팅장치.
- (정정) 제1항에 있어서, 상기 코팅컵의 내벽면에는 공기의 보다 원활한 흐름을 위하여 회전방향과 동일한 방향으로 나선형의 공기흐름 안내흠이 형성된 것을 특징으로 하는 웨이퍼 코팅장치
- (정정) 제1항에 있어서, 상기 웨이퍼 정렬수단은 회전척의 양측에 서로 대향되는 방향으로 이동가능하게 설치되는 것을 특징으로 하는 반도체 코팅장치.
- (정정) 제1항에 있어서, 상기 분사장치는 분사된 코팅액이 웨이퍼상에서 보다 고르게 확산되어 퍼지도록 하기 위하여 질소가스 분사구가 분사구 헤드에 추가로 설치되고, 상기 질소가스 분사구를 통해 질소가스를 공급하기 위한 질소가스 라인이 설치된 것을 특징으로 하는 웨이퍼 코팅장치.
