What Is UHV and What Industries Use It?
Ultra-high vacuum (UHV) refers to a pressure regime at or below approximately 10⁻⁹ torr (~1.3×10⁻⁹ mbar). At these pressures, gas-surface interactions and trace leak paths dominate system behavior more than bulk gas flow does. UHV is used in semiconductor manufacturing, surface science, synchrotron beamlines, electron microscopy, quantum and cryogenic platforms,
