ABSTRACT:
An apparatus and a method for producing single crystal semiconductor particulate in near spherical shape and the particulate product so formed is accomplished by producing uniform, monosized, near spherical droplets; identifying the position of an undercooled droplet in a nucleation zone; and seeding the identified droplet in the nucleation zone to initiate single crystal growth in the droplet.
