Semiconductor Manufacturing International Corp , China's largest contract chipmaker, plans to significantly raise its production capacity this year to meet strong market demand, after posting record-high net profit and revenue last year. The Shanghai-based company has budgeted about US$2.1 billion in capital expenditure for its foundry operations, up from US$1.4 billion last year, to ratchet up the capabilities at three of its six fabrication plants, or fabs, on the mainland.
