IPC: C30B15/22
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the multicrystallization of a single crystal under pulling and to automatically clamp the single crystal by clamping the single crystal under pulling by means of clampers. SOLUTION: A wire 1 is pulled down to immerse a seed crystal 3 into the surface of the Si melt 11 in a quartz crucible 10. At this time, arms 12, 13 stand by in the positions where their front ends do not come into contact with the Si melt 11. The front ends of the clamping arms 12 are held open so as not to come into contact with a diametrally expanding part under pulling up. A neck part 4, diametrally expanding part 5, constricted part 6 and crystalline body part 7 are formed under the seed crystal 3 by pulling the wire 1. When the contact of the front surface of the diametrally expanding part 5 with the front ends of the contact/detecting arms 13 during the pulling is detected by a sensor 14, the front ends of the clamping arms 12 are so driven as to be closed, by which the constricted part 6 is clamped.  The wire 1 and the arms 12, 13 are pulled while both are integrally rotated when the clamping is completed.

IPC: H01L33/00
Filed: 1991-04-26
Abstract: PURPOSE:To eliminate a stepped part between the jointed sections of a head substrate by pushing up the head substrate from below to press it against a stay using a thrust device which is introduced through a hole in a base substrate, holding the head substrate with the stay, and allowing an adhesive to be cured with the head substrate pressed against the stay. CONSTITUTION:A base substrate 1 is supported using a fixing block 10 and a stay 15 is pushed down until it presses the surface of head substrates 3, 4 softly at which point of time, pressing down the stay is stopped. Next, a microhead 13 is pressed downward to press the head substrate 3 against the stay 15 strongly so that the position of the head substrate 3 is fixed. In addition, the head substrate 4 is pressed against the stay 15 by pushing up a microhead 14. In this case, the microhead 14 is operated with the simultaneous measurement of a stepped part between the jointed sections of the head substrates 3, 4 using a displacement gauge so that the stepped part falls within a range of 3mum or less. Finally an adhesive 2 is allowed to cure completely with the stepped part remaining as it is. Thus the stepped part between the jointed sections of the head substrates 3, 4 has no longer a problem yet to be solved from a practical point of view.
