Based on the historical space forecast data and corresponding actual data provided by a global semiconductor assembly and test company , the uncertainty of space planning was defined . during this analysis process , linear regression , grey prediction , neural network back propagation algorithm and confidence interval were applied , respectively , to define the uncertainty . compared with those methods , the confidence interval of historical space forecast error , calculated by mathematical statistics , was the reasonable method to define the space forecasting uncertainty 本文从半导体工厂长期生产能力计划的顶层即厂房生产面积的计划展开,对一跨国半导体封装测试公司提供的厂房生产面积的长期历史预测数据以及对应的真实数据进行分析,采用线性回归,灰预测,神经网络bp算法,基于数理统计的置信区间的求解等方法分别定义厂房生产面积预测的不确定度,经多种方法的比较得出,基于数理统计方法求解出的生产面积历史预测误差置信区间能直观清楚地标定不确定度。
The technology used in the hbt production process is extremely complex ; advanced wireless semiconductor is one of only three companies in the world that possess this technology the other two are both located in the us . unlike the situation with other silicon chip products , japanese and korean manufacturers have yet to master hbt technology 德信科技成立于2001年，主要从事ic设计，并导入生产，生产过程中除晶圆代工和封装测试是委外处理外，其馀皆由德信科技掌握，包括行销。
