VACUUM APPARATUS FOR THE GERMINATION OF DENDRITIC STRIPS FROM SEMICONDUCTIVE MATERIALS

Abstract : A vacuum apparatus for germinating dendritic strips out of semiconductor materials is described. The apparatus consists of a vacuum chamber in the cavity of which is a crucible with the original material fastened on a movable rod, a heater, and a rod. For the purpose of increasing the productivity of the apparatus in the cavity of the vacuum chamber there is eccentrically set a container which makes a turning movement in the horizontal plane for the collection of the cutoff strips, and in the wall of the chamber is mounted an attachment for cutting off the germinated strips from the seeding with the aid of an electric arc, designed in the form of two electrodes fastened on the end of the metallic tube and a rod set inside of it electrically insulating one from the other.
