According to International Data Corporation (IDC), 2009 worldwide semiconductor revenues declined to $225.1 billion (decrease of 9%). The top five chip suppliers were Intel, Samsung, Texas Instruments, Toshiba, and Qualcomm. The five suppliers maintained about 34.3% of the semiconductor market. So far, 2010 appears to be very strong. Semiconductor inventory checks indicate strong demand in the first half of 2010 with order rates expected to normalize in the second half of the year. Assuming there are no macroeconomic shocks to global economy, IDC expects 16-18% year-over-year semiconductor revenue growth for 2010.
