At the heart of my MacBook Pro laptop, which is a couple years old at this point, is a Core 2 Duo chip from Intel. This is one of Intel's Penryn family of chips, and was therefore probably manufactured at Intel's relatively new fabrication facility in Chandler, Arizona. Computerworld's Sharon Gaudin wrote about this fab when it opened in 2007. Intel has other factories in the American Southwest, in California, and in Ireland and Israel.
