(Reuters) – Acer Inc has named former TSMC sales executive Jason Chen its new CEO as of January 1, appointing a chipmaking industry veteran to the helm of a Taiwanese company struggling to overcome sluggish PC sales. Chen takes over executive duties from company founder Stan Shih, who returned to the company in November and will remain Acers Chairman, Acer said in a statement on Monday. Chen, who worked for Intel Corp for 14 years before joining Taiwan Semiconductor Manufacturing Co, is currently TSMCs senior vice president of worldwide sales and marketing, a job he has held since 2008.
