  • Method of treating adherent semiconductor particles to break them apart
    Patent number: 5413285
    Abstract: Adherent silicon spheres (10) are broken apart into separate spheres by entraining them in a high velocity gas stream (12) which is directed at a surface (20). When the adherent spheres (10) impact on the surface (20) they break apart. The gas (12) and the separated spheres (10) are directed away from the surface (20) along divergent paths and the spheres (10) are collected for use.
