  • Crystallized polycrystalline semiconductor device
    Patent number: 5192991
    Abstract: A polycrystalline semiconductor device and a method of manufacturing the device are disclosed. An amorphous semiconductor film is deposited on a glass substrate and given thermal treatment at a crystallization temperature of 600.degree. C. or lower to form a polycrystalline photoconductive strucutre. The substrate is made from a material having the property of contracting at a percentage different than the semiconductor film by 10% or less, the contraction being caused by the thermal treatment.
