Abstract:
A system and method for performing diffusion on a three-dimensional substrate is provided. The system includes a furnace for providing a doped (e. g. , p-type) molten semiconductor material and a dropper for converting the molten semiconductor material into a series of uniformly sized droplets. The droplets are then provided to a first tube where they solidify into a semiconductor crystals. The semiconductor crystals are then heated for a predetermined period of time until an outer layer of the semiconductor crystals is melted. The melted outer layer can then be doped (e. g. , n-type) and then allowed to re-solidify. As a result, a plurality of spherical shaped p-n devices is created.
