Infineon Strengthens Its Position as the Market Leader in Power Semiconductors – Renewable Energy Sources and Smart Grids Opens Up Additional Growth Potential

Neubiberg, Germany – October 25, 2011 – Infineon Technologies is the global market leader in power semiconductors for the eighth consecutive year. According to IMS Research* data, Infineon again strengthened its position in 2010 and commands an 11.2 percent share of the overall market, ahead of Toshiba (6.8%), STMicroelectronics (6.5%) and Mitsubishi (6.5%). The IMS Research study shows that Infineon holds a market share of 8.6 percent in the discrete power semiconductor segment, making the company the clear number one there for the first time. “We are delighted to have not just retained our pole position in the power semiconductor market, but also to have strengthened it. Infineon is now also the clear leader  in the power discretes market,” said Arunjai Mittal, Division President of the Industrial & Multimarket Division at Infineon Technologies. “The energy distribution from  renewable energy sources requires efficient power lines and smart grids. This opens up additional growth opportunities for Infineon as leading provider of key components for raising energy efficiency – from energy generation and distribution to consumption.” IMS Research continues to see the longer-term prospects of the global power semiconductor market in a very positive light and forecasts market growth by around 50 percent to reach about US dollar 24.0 billion by 2015. Having undergone a distinct decline in 2009, the global power semiconductor market recovered in 2010, increasing by 40 percent to approximately US dollar 16 billion. That is two billion more than in the previous record year of 2008. The market for power semiconductor modules increased by 58 percent in 2010 to close on US dollar 3.5 billion. The power modules market growth is being driven primarily by industrial motor drives, renewable energy, hybrid and electric cars, and consumer electronics. In 2010, growth of the power modules market outpaced that of power discretes, which was up 37 percent to US dollars 12.3 billion. This segment benefited particularly from high demand in the sectors of PCs and servers, lighting applications, energy-efficient industrial and renewable energy applications, and household electronics. An increase in the production of air-conditioning systems and washing machines with variable speed drives (VSD) is being seen particularly in China. Power semiconductors are instrumental in feeding as much as possible of the electric power harnessed from wind or solar into the grid, and in minimizing energy loss in long-distance transmission from the place where it is generated to the place where it is consumed. These energy-saving chips also enable efficient power supply for computers, servers and domestic appliances, and are essential for an efficient control of electric motors. In order to take the success story of energy-saving chips forward, Infineon is already working intensively on future generations of power semiconductors. On October 10, 2011 the company announced having reached a technological milestone: Infineon became the world’s first supplier to produce chips (“first silicon”) on a 300-millimeter thin wafer for power semiconductors.  At the end of July Infineon announced setting up Dresden as the site for high-volume production of 300-millimeter power semiconductors as part of the investment plans. Infineon will invest around Euro 250 million until 2014 for this purpose and will create approximately 250 jobs in Dresden.
