What a difference a year makes or, more accurately, the final few months of a year. Semiconductor analysts entered 2004 with a strong outlook for semiconductor revenue growth—20-30% for many, with a reduced but still healthy forecast for 2005. However, the past 3-4 months have given these same analysts a few gray hairs. As a result, almost all have reduced their chip revenue forecast for 2005 from low double digits to just a few percent or, in some cases, zero. This reflects a view that the world economy, although continuing to rebound from the recent recession, is not recovering quite as fast as initially anticipated.
According to a Semiconductor Industry Association (SIA) forecast, slow growth in 2005 is pervasive throughout many semiconductor segments, with projected 2005 revenue changes of: -0.2% for discrete components, 12.8% for optoelectronics (one of the bright spots for 2005), 1.2% for analog, 1.7% for MOS logic, 2.3% for microprocessors, 6.9% for DSP, -14.7% for DRAM, and -1.8% for Flash memory. Keep in mind, however, this follows a very positive growth year in 2004.
