    • PURPOSE: Silicon single crystal wafer was manufactured by cz(czochralski) method with OSF or nuclear of OSF of distributed ring shape generating in thermal oxidation or without defect detected by FPD(Flow Pattern Defect), COP(Crystal Originated Particle), L/D(Large Disclocation), LSTD(Laser Scattering Topography Defect) or Cu decoration in whole wafer. CONSTITUTION: The present invention provided silicon single crystal wafer without grow-in defects by controlling temperature in reactor for delta G to be 0 or - value by pulling silicon single crystal. Said delta G is the difference between temperature grade Gc(°C/min) in center of crystal and temperature grade Ge(°C/min) around of crystal, delta G=(Ge-Gc) and G is temperature grade from melting point nearby liquid-solid interface of crystal to 1400°C.
    • 目的:采用cz(czochralski)方法制备硅单晶片,或用FPD(流动型缺陷),COP(晶体起始粒子),L / D等检测到的热氧化或无缺陷产生分布环形的OSF或OSF核 (大位移),LSTD(激光散射地形缺陷)或整个晶片中的Cu装饰。 构成:本发明提供了通过将反应器中的温度控制为ΔG为0或者通过拉硅单晶而不产生增长缺陷的硅单晶晶片。 所述δG是晶体中心的温度等级Gc(℃/ min)和晶体周围温度等级Ge(℃/ min)之间的差值,ΔG=(Ge-Gc),G是熔点的温度等级 附近液晶界面的液晶到1400°C。

    • Proposed is an improvement in the method and single crystal growing chamber for the preparation of a single crystal rod of silicon by the Czochralski method, according to which the distance between the surface of the melt of silicon contained in a crucible and the lower surface of the top wall of the crystal growing chamber is equal to or larger than the diameter of the crucible and the heat-insulating cylinder surrounding the crucible containing the melt of silicon and the heater has such a height as to reach the lower surface of the top wall of the chamber so as to keep the single crystal rod under growing is kept at a temperature not lower than 700 DEG C until reaching the lower surface of the top wall of the chamber thereby decreasing the density of the crystal defects of BMD type in the seed end of the single crystal rod as grown so that the uniformity in the distribution of BMD density is increased throughout the single crystal rod.
    • 提出了用切克劳斯基法制备单晶硅棒的方法和单晶生长室的改进,根据该方法和单晶生长室,坩埚中所含的硅熔体表面与硅晶片下表面之间的距离 晶体生长室的顶壁等于或大于坩埚的直径,并且围绕包含硅熔体的坩埚的绝热筒体和加热器具有这样的高度,即其到达顶壁的下表面 保持单晶棒生长的腔室保持在不低于700℃的温度下直到达到腔室顶壁的下表面,从而降低种子端的BMD型晶体缺陷的密度 生长的单晶棒,以致在整个单晶棒中BMD密度分布的均匀性增加。
