Title: Method and device for pulling single crystal of compound semiconductor
Inventor: AKAI SHINICHI
IPC: H01L21/208
Filed: 1982-03-31
Abstract: PURPOSE:To enable the pulling of a titled single crystal having a specified compsn. in the compsn. range near the m.p. of a compd. semiconductor by bisecting the melt of a raw material to the melt for growth and supply by means of a partition wall having a small hole at the lower part and making the deviation of both melts from the compsn. of a chemical equiv. ratio different from each other. CONSTITUTION:The raw material melt 9 in an inside crucible 13 and the raw material melt 10 in a quartz crucible 2 are covered respectively with the layers of liquid capsule agents 8, 11 in the stage of pulling, for example, a GaSb single crystal. A single crystal seed 7 is pulled under rotation by an upper driving shaft 6 thereby growing a single crystal 12. The height of the melt 9 in the crucible 13 decreases and the atom% of Sb in the remaining melt is going to increase with the growth of said single crystal, but the melt 10 having a relatively higher ratio of Ga on the outer side is supplied through a small hole 14; therefore, the excess Sb is offset. Thus, the compsn. of the melt 9 for growth is eventually maintained approximately constant as fas as the melt 10 for supply remains, and the long-sized GaSb single crystal is grown.
