摘要： A method for doping crystals is disclosed. The method includes a receiver for receiving semiconductor spheres and doping powder. The semiconductor spheres and dopant powder are then directed to a chamber defined within an enclosure. The chamber maintains a heated, inert atmosphere with which to diffuse the dopant to the semiconductor spheres.

摘要： A system and method for processing crystals is disclosed. The system includes a receiver tube for receiving semiconductor granules. The granules are then directed to a chamber defined within an enclosure. The chamber maintains a heated, inert atmosphere with which to melt the semiconductor granules into a molten mass. A nozzle, located at one end of the chamber, creates droplets from the molten mass, which then drop through a long drop tube. As the droplets move through the drop tube, they form spherical shaped semiconductor crystals. The drop tube is heated and the spherical shaped semiconductor crystals may be single crystals. An inductively coupled plasma torch positioned between the nozzle and the drop tube melts the droplets, but leaving a seed in-situ, or the droplets may be melted and a seed injected in-situ. The seed can thereby facilitate crystallization.

摘要： A system and method for forming spherical semiconductor crystals is disclosed. The system includes a receiver tube 18 for receiving semiconductor granules 104. The granules are then directed to a chamber 14 defined within an enclosure 20. The chamber maintains a heated, inert atmosphere with which to melt the semiconductor granules into a molten mass. A nozzle, 40, creates droplets from the molten mass, which then drop through a long drop tube 16. As the droplets move through the drop tube, they form spherical shaped semiconductor crystals 112. The drop tube is heated and the spherical shaped semiconductor crystals may be single crystals. An inductively coupled plasma torch positioned between the nozzle and the drop tube melts the droplets, but leaving a seed in-situ. The seed can thereby facilitate crystallization.
