Title: Manufacture of semiconductor substrate
Inventor: TANBA AKIHIRO
IPC: H01L21/20
Filed: 1986-05-23
Abstract: PURPOSE:To enable the stable growth of crystal by making the flow of heat due to the endothermic effect of seed crystal coincide with the easy growth direction of a semiconductor layer by considering the relation between the shape of the region encircled by the seed crystal and the direction of zone melting scanning. CONSTITUTION:An upper semiconductor layer 2 is encircled by seed crystal 1 and the flow of heat of a melted region 3 is accelerated by the endothermic effect of the seed crystal 1. The relation between the shape of the region encircled by the seed crystal 1 and the proceeding direction of zone melting is to make the combined flow of heat coincide with the easy growth direction of the upper semiconductor layer for the crystal orientation of the seed crystal. Crystal information is also smoothly transferred by encircling the SOI 2 with the seed crystal 1. This prevents the generation of a subgrain boundary or a grain boundary.

Abstract: PURPOSE: To control the dip amount of a pipe into a sample liquid and the suction amount of the sample liquid, by gushing air from the pipet, detecting the change of a back pressure generated in the pipet when air comes into- contact with the surface of the sample liquid, and obtaining the liquid level. CONSTITUTION: A pump 32 is driven in a compression mode by a control part 38, so that air is gushed out from a pipet 14 supported at a transfer stage 10. When the pipet 14 comes into contact with a sample 19 in a test tube 18 subsequent to the fall of the stage 10, a back pressure is generated in a tube 28, which is detected by a transducer 36. In consequence, the control part 38 raises the pipet 14 and sends a command to discharge the air remaining in a system of the tube 28. Thereafter, the control part 38 lowers the stage 10 again by a total distance of a detected liquid level of the sample 19 and a predetermined distance required for the sample 19 in the test tube 18 to be sucked a predetermined amount. When the pipet 14 is dipped the distance in the sample 19, the pump 32 is driven in a discharge mode, whereby the interior of the tube 28 is turned to a predetermined vacuum.  The predetermined amount of the sample 19 is thus sucked in the pipet 14.
