Silicon Forest

The Silicon Forest is a nickname for the Portland metropolitan area in Oregon and Southwest Washington. Like the Silicon Valley, it refers to the cluster of high tech companies present there. In Portland, these companies specialize in

• output devices like displays and printers
• semiconductor device fabrication
• software

and related areas.

The high-tech industry in the Portland area dates back to at least the 1940s, with Tektronix and Electro Scientific Industries as pioneers. These two companies, and later Intel, led to the creation of a number of spin-offs or start-ups, some of which were remarkably successful.
