 SMIC: expansion and profitability 
 (By LM4871 amplifier chip 4871, the representative of the business of the amplifier IC4871 supplier Zhang finishing fir Gui,) 

 In November 2009, the continued expansion pressure the weight of several years in a row loss SMIC CEO Richard Chang resign. Take over the baton of the former Applied Materials executive vice president and president of Asia, the Shanghai Hua Hong Group CEO Dr. Wang first faced with is how to turn around, how to hold the balance between expansion and profitability. 

 In February 2011, the SMIC announced earnings of the previous year. SMIC in 2010 net profit of $ 14 million and 2009 net loss of $ 962.5 million compared to losses, and the company's full year net profit new record. SMIC in the case of five consecutive years of losses to achieve full-year earnings for the first time, Dr. Wang's turn in the first respondents are very bright. 

 Dr. Wang took office, SMIC was considered to be a "mess". Ten consecutive quarters of losses, TSMC report the theft of trade secrets, but also dragged down the financial pressure brought about by the diamond-shaped layout. Dr. Wang in the hands only hold $ 440 million in cash and current liabilities of up to $ 1.07 billion. Then SMIC is a "hot potato". 

 Took over this "hot potato" for anyone to need a lot of courage for Dr. Wang is no exception. To do something practical for China's semiconductor industry has been the ambition of Dr. Wang. SMIC, China's largest and most advanced semiconductor manufacturing companies, is undoubtedly the best Dr. Wang's stage. Dr. Wang is pleased to accept this challenge. 

 With the stage is also an actor, Dr. Wang took office after the primary work as a drama director of SMIC, the formation of a new core team. Zeng Lin early February 2010, SMIC appointed Yang Shining a former Chartered Semiconductor chief technology officer and senior vice president of operations to chief operating officer, had served as TSMC's chief financial officer and senior vice president in the period 1991-1997 is Chief Financial Officer, has served as senior vice president of corporate marketing and sales in early 2008 to join SMIC quarter gram for the company's chief marketing officer, a new management team is beginning to take shape. 

 With the new management team gradually put in place, the company's strategic direction becomes clearer. The first and stronger again, bigger and stronger changes from the previous profit as the supreme principle. First taken streamlining within the company, through the agency of the "flat", to improve the efficiency between internal departments, and strengthen the speed of market response. Moreover, in October 2010, the SMIC to give up right to Chengdu into the core of the 200mm wafer fab management. Dr. Wang by gradual modification of the business to the limited funds focus on the profitability of the better areas. 

 Dr. Wang believes that the driving force of economic development in the next decade is the mobile Internet, applications integration and development of emerging markets including China. Dr. Wang held on March 13, 2011 China International Semiconductor Technology Seminar "(CSTIC) keynote address, said that" five years of smart Internet devices shipments of 3.5 times the rate of growth, the mobile Internet with unlimited space for development. now 80% of the world mobile phone, while only 20% of the computer, in other words, the broadband network only covers 20% of the world. phone mobile Internet market will be very large , especially in developing countries will be an important market for mobile Internet and the development of mobile Internet is being or will be the introduction of a new application platform co-exist with the current "Wintel" platform, or replace it gradually. " 

 Dr. Wang believes that emerging markets drive the economy in fact, integration with the mobile Internet and applications interact, precisely because of the emerging markets infrastructure lag behind more developed countries, demand for mobile Internet and application integration will be more vigorous. Electronic devices 'non-leading edge' chips increased from 5% to 25%, which is now mobile Internet devices presented by one of the characteristics of this emerging market has gradually become the main consumer of electronic equipment because the development country consumers for higher sensitivity to commodity prices, which put forward higher requirements to the cost of electronic products as well as the chip vendor's control, "Dr. Wang said. According to iSuppli's forecast, the 2013 line is less than 100 nm and greater than 100 nm semiconductor products and basically each half of the total semiconductor sales. Based on the industrial development trend, it may simply look at the so-called advanced technology come to what extent the evaluation of a semiconductor manufacturer, may be biased, also should be integrated to consider the vendor's product features and cost control. 

 Based on industry trends and market awareness, Dr. Wang through a series of personnel changes, streamlining the organization and the strategic adjustment of the SMIC in 2010 and finally in the case of five consecutive years of losses for the first time full-year earnings. Dr. Wang owned by the SMIC profitability of the main reasons are: a good market, good morale and good team, his team now is very important.
