Abstract
Devices fabricated from certain compound semiconductors of the group IV-VI series are provided with optically transparent coatings of barium fluoride, calcium fluoride, or strontium fluoride. These coating materials are insulators, chemically and electrically inert to the semiconductors, easily applied, and mechanically compatible thus making excellent protective coatings. In addition the coatings can act as diffusion masks in device fabrication thus enhancing planar device processing.
