我国半导体工业的产品代谢研究

利用产品代谢分析方法首次对我国半导体工业的整体硅元素和能源利用率进行了定量研究.根据我国半导体工业的产品代谢模型计算得出2002年我国半导体工业的硅元素利用率为2.6%,每生产1 kg硅总能耗为5 704kW·h,而1998年全球半导体工业硅元素平均利用率为9.6%,生产1kg硅总能耗为2 130 kW·h.进一步在产品链和关键环节分析基础上,确定了我国在硅元素利用率和能源利用率上与世界平均水平差距最大的环节.通过成因分析,提出了改善措施和途径. 

A Study on Product Metabolism for China Semiconductor Industry

A quantitative analysis is made for the first time on China semiconductor industry for its overall efficiencies in using element silicon and energy by product metabolism method. Results from calculation based upon a product metabolism model for China’s semiconductor industry show that in 2002 China’s element silicon utilization efficiency in its semiconductor industry was 2.6% and the total energy consumption was 5 704 kW·h to produce 1 kg silicon，compared with the 1998 world average 9.6% of element silicon utilization efficiency in semiconductor industry and total energy consumption 2 1(0 kW*h to produce 1 kg silicon. A further study based upon product chain analysis and key process analysis identifies the process where China is behind the world average the most in element silicon utilization efficiency and energy utilization efficiency. Measures and ways for improvement are put forward through a cause analysis .
