  • Method of making a semiconductor device to improve conductivity of amorphous silicon films
    Patent number: 4472210
    Abstract: In making a semiconductor device wherein a film of a non-single crystalline silicon, such as polycrystalline or amorphous silicon, is deposited on a substrate and then doped, particularly by ion implantation, to make the film conductive, the conductivity of the film is increased by pre-annealing the film at a temperature of 1000.degree. C. to 1200.degree. C. in an inert ambient before doping the film.
