Semiconductor sales dropped in October, but the decline worsened in November. According to the Semiconductor Industry Association (SIA), sales for November fell to $20.8 billion, a 9.8% decrease from the $23.1 billion recorded in November 2007.

Chip sales were hit the hardest in the U.S., dropping 19.5% between November 2007 and November 2008. We’ve seen some of the effects of this in layoffs by major players like AMD and Lenovo, among many others. One more industry that’s suffering in these difficult times.
