HSINCHU, Taiwan, March 14, 2011 - United Microelectronics Corporation (NYSE: UMC; TWSE: 2303) ("UMC" or "The Company"), a leading global semiconductor foundry, today announced the donation of power electronics laboratory equipment to the Department of Electrical Engineering at National Taiwan University (NTU). The company has also established a UMC-funded green energy technology seminar at NTU to research power electronics, power systems, and green electric energy. The contribution will help cultivate Taiwan's technical talent in green energy fields, including renewable energy sources, solar energy and energy-saving lighting such as next-generation light emitting diodes (LED). At the same time, UMC subsidiary NexPower Technology Corporation also contributed 10-kilowatt peak (kWp) silicon thin film photovoltaic (PV) module systems that it manufactures, to provide students with resources to integrate theory and practice in their R&D experiments, as part of fostering Taiwan's future green energy technical talent.

Jack Lai, Vice President of Technology at UMC, said: "Green energy is currently a major target industry for new business development at UMC. We expect to make revolutionary breakthroughs in green energy technology and applications and contribute substantially to energy conservation and carbon reduction as part of fulfilling our duties as a corporate citizen. At the same time, we are capitalizing on this transitional time within the industry to take an advantageous position and instill new momentum in sustainable operations. NTU's Department of Electrical Engineering has long been one of the most important incubators for technical talent, and through this collaboration, we hope to encourage top talent to enter the field. Now that alternative energy sources and a low-carbon environment are becoming ever more critical, we are getting a head start in building the human resources foundation for the future growth of the green energy industry."

UMC has dedicated itself to promoting low-carbon economic development by entering the low-carbon industry. In August 2009 the company formed its New Business Development Center, an internal group focusing on building complete supply chains, from raw materials to end products, for the renewable energy, solar energy and energy-saving lighting (i.e. next-generation LED) industries. New businesses that have stemmed from these efforts include NexPower, Taiwan's pioneering silicon thin film PV module manufacturer; Power Light Technology Co., provider of LED lighting equipment; and EverRich Energy Corporation, offering solar energy electromechanical engineering design and integration services.
