According to Gartner, global semiconductor revenue in 2012 totaled 2,976 one hundred million U.S. dollars, down 3% compared to 2011's $ 30.7 billion dollars. The world's top 25 semiconductor vendors revenues declined by 4.2%, larger than the industry average, while the proportion of the contribution of the global semiconductor revenue will not be higher than the proportion of share in 2012 ,68.2%, slightly lower than 2011's 69.2 %. After flat growth in 2012, in 2013, continuing the mobile device market strong growth as well as the transformation of the PC market trend, driven by growth of about 4.9% of the global semiconductor industry. This growth will promote global semiconductor sales to reach $ 319 billion in revenue in 2013, by contrast, less than 1% growth in 2012, IDC predicts. In addition, in view of the long-term from 2011 to 2016, the global semiconductor market will be increased 4.1%, compound annual growth rate (CAGR) is expected to reach 3,680 billion U.S. dollars in sales in 2016. Computer chip market in 2013 will have growth of 1.7% from 2011 to 2016 compared with 2012 , the CAGR is 1.7%. The mobile PC market semiconductor revenue is expected to grow by 5.5% over 2012. Communications chip market is expected to grow 6.5% compared with 2012, an estimated CAGR of 5.5% in 2011-2016. However, 4G mobile phone chip sales will be significantly higher than the 2012 growth of 140%, within five years CAGR of 103.4%. Driven by tablet PCs, e-book reader and STB products market， in 2013 CE semiconductor market is expected to grow 9.8% in 2011-12 and in 2016 is expected to reach 6% CAGR.
