Market research firm, IHS estimates that the global semiconductor market will grow 9.7% industrial compound average annual growth rate (CAGR), from 2013's $ 34.8 billion scale, growing to $ 55.2 billion in 2018; corporate capital spending and sustained macroeconomic growth , especially the United States and China, will help motivate the demand for industrial semiconductor market and sales growth.According to IHS's latest report, factory automation, building / home control and commercial aircraft demand for industrial semiconductor components is increasing; in fact, industrial semiconductor sales in the third quarter of 2014 quarter growth rate is still only 4.7%, but in 2014 the whole the estimated annual sales growth over the previous year by 16.8%. Semiconductor products in a variety of industries, the growth rate of the light-emitting LED particularly strong sales growth rate of 23.4%, an increase from 2013 of $ 6.3 billion to $ 7.7 billion in 2014; discrete power transistor and thyristor (thyristor) Sales the growth rate was 13.4%, an increase from $ 5.5 billion to $ 6.3 billion. By the US-led global economy in 2014 strong growth is expected to force the sustainable until 2018; US economic growth situation is more extensive than the other on a regional basis, the housing market stabilize, consumer finance and credit markets improve, corporate capital spending also showed increases. US GDP growth rate in 2014 was estimated at 2.4%, while the 2015 and 2016 may have 3.1% and 2.7% growth. Galoso pointed to industrial semiconductor product categories, optical semiconductors, analog chips and discrete components are the three markets. The industrial-scale use of optical chips by revenue estimate of $ 8.6 billion in 2013, increased to $ 15.9 billion in 2018; such chips include general lighting of the LED, the overall optical wafer revenue accounted for 72% of revenue in 2013 This proportion is estimated to increase to 78.4% in 2018. Motor drive applications in factory automation and energy distribution, conversion and storage of optical coupler (optocoupler) is the second largest revenue optical semiconductor products.
