数理统计方法在IC大生产中的应用──试论工序能力指数与成品率的关系

The Application of Mathematic-Statistical Method in IC Mass Production──On the Relationship Between Processing Capability Index and Yield

单道工序能力指数Cp和单道工序的成品率y是全面质量管理TQC（TotalQualityControl）的两个关键参数．本文利用余误差函数表和线性插值修正法计算了不同Cp的y值，并给出了对应表格，从而大大方便了数理统计方法在工业化大生产中的实际应用．

Both processing capability index Cp and yield y in one step are key parameters in Total Quality Control(TQC). The function y of Cp is calculated by means of Co-error function table and linear interpolating correction in this paper, and a table of y-Cp is also given. It will he very convenient to apply mathematic-statistical method to industrial mass production.
