Cascade Microtech is a semiconductor test equipment manufacturer based in Beaverton in the Portland metropolitan area of the United States.

In the early 1980s, Eric W. Strid and K. Reed Gleason, employees at Tektronix (Tek), attempted to get their bosses to make a microwave wafer probe for testing microchips.

[12] After years of delay, Cascade Microtech filed for an IPO with the United States Securities & Exchange Commission in March 2004, hoping to raise $85 million.

[13][14] The company employed 243 and had revenues of $50.6 million when they filed for the IPO, and major customers included Intel and Infineon.

[15] On December 15, 2004, the company started trading on the NASDAQ market, with an initial price of $14 per share under the ticker symbol CSCD.
