Claims (11)
- 반도체소재의 단결정 제조방법에 있어서,반도체소재의 용융물을 포함한 도가니를 구비하여, 그 단결정을 용융물에서 인발하며,그 도가니를 둘러싼 측면히터(side heater)를 사용하여 그 용융물을 가열하고,그 단결정을 둘러싸며 용융물위에 설치한 환상가열장치를 사용하여 그 단결정을 중심으로 하는 환상영역의 용융물을 추가로 가열하며,그 환상가열장치로 단결정을 가열하는 것을 회피하고,그 환상가열장치와 단결정 사이의 거리를 도가니의 벽과 그 환상가열장치 사이의 거리보다 더 짧게 유지시킴을 특징으로 하는 단결정 제조방법.
- 제1항에 있어서,그 용융물이 환상가열장치에 의해 추가로 가열할 때 그 측면히터와 적합할 경우 저면히터의 가열출력(heating power)을 감소시킴을 특징으로 하는 단결정 제조방법.
- 제1항에 있어서,단결정을 인발하기 전에 그 용융물을 제조하며 그 용융물 제조에 필요한 열의 일부는 환상가열장치에 의해 공급함을 특징으로 하는 단결정 제조방법.
- 제1항에 있어서,그 환상가열장치는 그 가열출력의 신속한 조정(rapid control)에 사용됨을 특징으로 하는 단결정 제조방법.
- 제1항에 있어서,성장하는 단결정에서 산소함량은 측면히터와 선택적으로 저면히터의 가열출력과 함께 환상가열장치의 가열출력을 조정함으로써 변화시킴을 특징으로 하는 단결정 제조방법.
- 반도체소재의 단결정을 용융물에서 인발하는 장치에 있어서, 벽(wall)을 구비하고 반도체소재의 용융물을 포함한 도가니와,그 도가니를 둘러싼 측면히터(side heater)와,단결정을 중심으로 한 환상영역의 용융물을 가열하고, 그 단결정을 둘러싸며 용융물위에 설치시킨 환상가열장치를 구비하며,그 환상가열장치는 용융물만을 가열하고 단결정을 가열하지 않도록 위치시키며 단결정과 환상가열장치 사이의 거리는 그 환상가열장치와 도가니의 벽 사이의 거리보다 더 짧도록 구성함을 특징으로 하는 장치.
- 제6항에 있어서,환상가열장치는 용융물쪽으로 열복사(heat radiation)를 반사하는 리플렉터(reflector)임을 특징으로 하는 장치.
- 제6항에 있어서,환상가열장치는 용융물쪽으로 열복사를 반사하는 저항히터(resistance heater)임을 특징으로 하는 장치.
- 제6항에 있어서,환상가열장치는 단결정을 중심으로 하는 환상영역내의 용융물을 유도할 수 있게 가열하는 유도히터(indnction heater)임을 특징으로 하는 장치.
- 제6항에 있어서,환상가열장치는 단결정을 열차폐(thermally screen)하는 열실드(heat shield)의 하부에지에 고정함을 특징으로 하는 장치.
- 제6항에 있어서,단결정과 환상가열장치 사이에는 단열을 가짐을 특징으로 하는 장치.
