(7) Monitor Thin Film Deposition In Real Time With Bomco's UHV Windows "This is as close as anyone has come to windowless, optical access to an ultrahigh vacuum chamber."
As the demand for higher performance materials for semiconductors increases, so does the need for real-time information about crystal growth by molecular beam epitaxy (MBE). Optical access to the vacuum environment of this process is essential to determine such data as sample temperature, tolerances of layer thicknesses and composition Engineers at Bellcore and Bomco worked together to develop a UHV window suitable for this environment. This UHV window permits the use of optical pyrometry, elliposometry, light scattering and reflectance-difference ...
(3) Two Ways To Protect UHV Windows And Preserve Optical Access To MBE Chambers Constructed of stainless steel, the protective shields slip easily over the UHV flange and the clamp is tightened with a screw driver. The shields are available for all window sizes shown.
