  • System for regulating molecular flux and its application to co-evaporation techniques
    Patent number: 4160166
    Abstract: A system for automatic regulation of the density of a given molecular type at a pre-arranged point in an apparatus called a "flux or molecular jet", intended to make epitaxy layers. In a vacuum enclosure a probe for mass spectrometry analysis (electrostatic, four pole apparatus) picks up the types projected by evaporating units, ionizes them, filters and detects them as a function of their respective masses. The heating in each unit is regulated by a servo-control loop which contains means for analyzing the type concerned.
