  • Integrated multi-channel optical-based flux monitor and method
    Patent number: 6075588
    Abstract: An integrated dual beam multi-channel optical-based flux monitor and method of monitoring atomic absorption of a plurality of atomic species during epitaxial growth. Light from multiple sources is simultaneously passed through a region of deposition of material such that atomic absorption takes place. The light that passed through the region is then compared to light in a reference arm that did not pass through a region of atomic absorption. From this comparison the growth of an epitaxial layer can be carefully controlled.
