METHOD OF MAKING PHOTOSENSITIVE SILVER-PALLADIUM RESISTIVE FILM Russian patent published in 2015 - IPC G03C1/725 G03C1/74 H01L21/3105 

FIELD: physics, optics.

SUBSTANCE: invention relates to optoelectronics, particularly a method of making photosensitive materials and devices. A method of making a photosensitive silver-palladium resistive film includes forming, on the surface of a dielectric substrate, a layer of resistive paste consisting of silver oxide Ag₂O, palladium, fine glass particles and organic binder. The formed layer is dried and burned in an air atmosphere at 605-700°C. A glass layer is then removed from the surface of the obtained film by evaporation with high-power pulsed laser radiation with a wavelength in the absorption region of the glass. Use of laser radiation with a wavelength corresponding to the absorption maximum of the glass is preferable.

EFFECT: wider spectral range of operation of the photosensitive silver-palladium resistive film.
