Title: Growing semiconductor crystalline materials
Inventor: BARRACLOUGH KEITH GORDON
IPC: C30B15/30
Filed: 1990-09-07
Abstract: Semiconductor crystalline materials e.g. silicon, GaAs, are grown from a melt, e.g. using the Czochralski technique where a seed crystal is dipped into the melt then slowly withdrawn. Rotation of the growing crystal (6) is partly responsible for convective flows within the melt (5). Convective flows are reduced whilst radial uniformity is improved by subjected the crystal/melt interface to a shaped magnetic field. This magnetic field is rotationally symmetrical about the axis of crystal rotation, with a component of field parallel to this axis that is less than 500 gauss, preferably less than 200 gauss, with a value above 500 gauss at other parts of the melt. The field may be produced by two superconducting magnet coils (21, 22) spaced apart and arranged co-axially with the axis of crystal rotation. <IMAGE>
