Abstract
본 발명은 GaAs 다결정 성장에 관한 것으로, 종래의 2T-HB에서 Ga, Si와 석영 유리와의 웨팅 반응으로 인하여 GaAs 용액내의 도펀트(dopant)외에 불필요한 Si의 유입과 Ga 보우트의 균열 등이 초래되고, 전기로 이동시 GaAs 다결정 잉곳내의 온도차로 인한 웨팅 반응과 함께 잉곳의 균열이 발생되는 문제점을 해결하기 위하여, 1250~1260℃의 온도영역(T1)과 1150~1220℃의 온도영역(T2), 그리고 610~630℃의 온도영역(T3)을 설정하여 8~12시간 안정화한 후 전기로를 이동시켜 GaAs 다결정을 성장시키는 3T-HB법에 의한 고품위 GaAs 다결정 성장방법이다.The present invention relates to GaAs polycrystal growth, and in the conventional 2T-HB, due to the wetting reaction of Ga, Si and quartz glass, unnecessary inflow of Si and cracking of Ga-Boat, in addition to the dopant in the GaAs solution, is caused. in order to solve the problem of cracks in the ingot produced with the wetting reaction due to the temperature difference in the movement into an electric GaAs polycrystal ingot, the temperature range (T 1) and a temperature range of 1150 ~ 1220 ℃ of 1250 ~ 1260 ℃ (T 2) , And it is a high-quality GaAs polycrystal growth method by the 3T-HB method to grow the GaAs polycrystals by moving the electric furnace after stabilizing for 8 to 12 hours by setting the temperature region (T 3 ) of 610 ~ 630 ℃.
