    • By using a semiconductor single crystal pulling apparatus for growing single crystals by the Czochralski method while rotating the melt by a magnetic field and electric current, namely by the EMCZ method, which comprises a main pulling means (14) for pulling a single crystal, a holding mechanism for gripping an engaging stepped portion formed on the single crystal through engaging members (17) and a sub pulling means (15) for moving the holding mechanism up and down and in which an electric current is passed through the main pulling means (14) and through the sub pulling means (15), it is possible to prevent heavy single crystals from undergoing a falling accident and, at the same time, effectively reduce the power consumption. In this pulling apparatus, it is effective to feed an electric current to the sub pulling means (15) alone and it is desirable to dispose two or more electrodes (22) whether the pulling means is of a shaft type or wire type.
    • 通过使用半导体单晶拉制设备在通过磁场和电流旋转熔体的同时通过切克劳斯基法生长单晶,即通过包括用于拉制单晶的主拉引装置(14)的EMCZ方法, 保持机构,用于通过接合部件(17)和用于上下移动保持机构的副牵引机构(15)夹持形成在单晶体上的接合台阶部,并且电流通过主牵引机构(14 )并且通过副牵引装置(15),可以防止重的单晶发生坠落事故并且同时有效地降低功耗。 在该牵引装置中,仅向副牵引装置(15)供给电流是有效的,并且无论牵引装置是轴型还是线型,都希望设置两个或更多个电极(22)。 <图像>
