WAFER FLATNESS MEASUREMENTS
Valley Design will be exhibiting at LASER, World of Photonics in Munich Germany June 22-25, 2015. The exhibition is held at the Messe Munchen, and Valley will be at Booth #B1.127. This year's international trade fair and congress will be its 22nd, and features optical technologies, components, systems and applications. We will also be exhibiting at Semicon West July 14-16, 2015 in San Francisco, California. Semicon West is being held at the Moscone Center, and Valley will be at Booth #1446 in the South Hall. Semicon West is an important semiconductor and microelectronics industry event, and will feature emerging developments in 450mm technology, MEMS, advanced packaging, 3D IC and more.
We will be displaying a wide variety of product samples including:
