    • The present invention is to manufacture a low hydrogen-concentration silicon crystal having less micro defects caused from oxygen precipitation generated during an annealing process. Particularly, a silicon crystal including hydrogen concentration lower than 0.55.times.10.sup.11 cm.sup.-3, where the hydrogen concentration dependency is small and the micro defect density is less, may be used for a substrate of semiconductor devices. The low hydrogen-concentration silicon substrate is manufactured by measuring the hydrogen concentrations in a silicon crystal and in a hydrogen-doped silicon crystal having a known hydrogen concentration, where both the silicon crystals have been annealed at an equal condition so as to generate thermal donors therein, and by comparing thus measured hydrogen concentrations. The known hydrogen-doped silicon crystal has been prepared by a hydrogen-diffusing annealing in a hydrogen containing atmosphere, where the hydrogen concentration is calculated from the hydrogen partial pressure and the temperature of the annealing.
    • 本发明是制造在退火工序中产生的氧沉淀引起的微小缺陷少的低氢浓度硅晶体。 特别地,半导体器件的基板可以使用氢浓度低于0.55×10 11 cm -3的硅晶体,其氢浓度依赖性小,微缺陷密度较小。 通过测量硅晶体中的氢浓度和具有已知氢浓度的氢掺杂硅晶体制造低氢浓度硅衬底,其中两个硅晶体已经在相等的条件下退火,以便产生热供体 并通过比较如此测量的氢浓度。 已知的氢掺杂硅晶体已经通过在含氢气氛中的氢扩散退火制备,其中氢浓度由氢分压和退火温度计算。
