iSuppli forecasts worldwide semiconductor sales will hit $237.1 billion in 2005. The firm said last month that sales would grow 9.6% in 2005.
iSuppli cited lower sales forecasts for electronics equipment, which is expected to grow 6.2% in 2005, down from 10.1% this year.
The firm also cited growing chip stocks: excess inventories in the supply chain doubled last quarter, to $1.6 billion, iSuppli said.
2006 will mark the low point for IC sales, followed by a recovery in 2007 and 2008, iSuppli predicts.
