Affected by declined traditional PC industry in the second half 2012, the semiconductor industry, which appear small scale fluctuations. Into 2013, the market institutions predict that China will lead the next two years, the semiconductor market growth. In 2012, due to the mobile intelligent electronic products continue to impact, the traditional PC industry decline, resulting in the semiconductor market, there are some fluctuations. IDC's SAF report follow-up study more than 120 semiconductor companies. Most of the company's revenue has decreased, including the top ten companies in the eight. Last year, only 17 companies increased by more than 5% of revenue, or more than one billion U.S. dollars.This is the global semiconductor industry to have the first annual decline since 2009 which in the global chip market is a major event. In 2012 reproduction of negative growth. First half of 2012, the global semiconductor market decline significantly, down 5.1%. Overall, in 2012 the global semiconductor market reproduction of negative growth, dropped back to $ 291.56 billion market size, market growth rate fell 2.7%.However, IDC expects the semiconductor market revenue this year will increase by 3.5%. According to the U.S. Semiconductor Industry Association supports the World Semiconductor Trade Statistics for 2013 global semiconductor sales forecast that in 2013 the global semiconductor industry sales will reach $ 297.8 billion, compared with 2012's total sales rose 2.1%. WSTS forecast, Asia Pacific sales to an increase of 5.7% year on year increase of 5.3% in Europe, the Americas will grow by 1.6%, but Japan will sharply by 13.8%.According to projections made by WSTS, in 2013, the industry is expected in all regions of the semiconductor industry will show a steady moderate growth. It is predicted that in 2014 global semiconductor sales will grow by 5.1% to $ 312.9 billion; 2015 will further increase by 3.8%, reaching $ 324.9 billion. WSTS half-year industry forecasts through extensive convene global semiconductor companies to provide accurate and timely indicators of semiconductor trends and made.
