| Summary: | 碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 98 === Taiwan is surrounded by sea, due to lack of natural resources, it extremely depends on importing sources of energy. Also, the main industry structure transformed to high technical and highly-energy-exhausted electronic industry. Kyoto Protocol, which established in December, 1997, emphasize the importance of Global issue “Energy Saving and Carbon Emission Reduction”; therefore, all electronic plants are all focus on how to improve the energy efficiency, decrease production cost, and being more competitive throughout countries.
In this study, we survey three products, which are 12”Electronic-Grade Si Wafer, DRAM Module and Photomask for silicon wafer in order to provide a specific energy consumption data as a reference for the related fields. Through this series of information, we could improve energy efficiency, decrease environmental load, and also become more competitive in Taiwanese electronic industry; moreover, we focus on SEC for all major energy consumption sectors in the DRAM supply chain, include silicon wafer (ingot), wafer fabrication, IC assembly, IC testing, Modulization, and PCB.
Results show that the energy consumption of a single unit of products from DRAM Supply Chain is 4.67 kWh/PCS. Based on the annual shipment (85,136,366 PCS/yr), we find the whole DRAM supply chain consumes a total of 397,331,726kWh of energy, emitting 252,703 tons of CO2.
