	The name is analogous to Silicon Valley. In the greater Portland area, these companies have traditionally specialized in hardware — specifically test-and-measurement equipment (Tektronix), computer chips (Intel and an array of smaller chip manufacturers), electronic displays (InFocus, Planar Systems and Pixelworks) and printers (Hewlett-Packard Co, Xerox and Epson). There is a small clean technology emphasis in the area.
