Abstract
PURPOSE: Both of the starting rod and seed rod and held horizontally and supersonic generators and supersonic reflectors are set opposite to each other respectively on both upper and lower sides of the heaters to grow single crystal of uniform composition with no gravity influence on the distribution of costituents in the melted zone.
CONSTITUTION: The starting rod and seed rod are held horizontally on the holders 8 in the quartz tube 9 and the light from the heating lamps 1 is concentrated with reflectors 2 to melt the starting rod and form the floating zone. At the same time, the starting rod 5 and the seed rod 6 are made to revolve through the holders 8 and supersonic waves are generated from the generator 3 and reflected with the supersonic reflectors 4 to control the change in supersonic pressure to give the floating force to the melted body 7. When the melted state becomes stable, both of the starting rod 5 and seed rod 6 are shifted to the side of the seed rod 6 to effect the melting of the starting rod 5 and the growth of single crystal on the seed rod 6.
