PROCESS OF MANUFACTURE OF LASER TARGET OF CATHODE-RAY TUBE ON BASE OF MONOCRYSTAL OF SEMICONDUCTOR OF A 002B - 006 TYPE Russian patent published in 1995 - IPC

FIELD: manufacture of laser cathode-ray tubes. SUBSTANCE: chemical and mechanical polishing of first surface of starting semiconductor plate is conducted. Heterostructure composed of monocrystal film of direct-gap semiconductor of A₂B₆, type grown on substrate of semiconductor of A₃B₅, type is used as starting plate. Output mirror is applied and heterostructure is anchored on cooling agent line. Then substrate of semiconductor of A₃B₅ type is removed by method of selective chemical pickling, for instance with aqueous solution of H₂O₂ and NH₄OH. Surface of monocrystal film of A₃B₅ semiconductor contacting A₂B₆ semiconductor substrate is polished by chemical method and dummy mirror in the form of reflecting coat is applied on it. EFFECT: facilitated manufacture of laser targets. 3 cl, 1 dwg
