Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To prevent a single crystal having a large diameter and a heavy weight from dropping and surely and safely pull the single crystal in a decompressed chamber. SOLUTION: A seed crystal 24a is dipped in an Si melt in a quartz crucible 14 and then pulled to thereby form a small-diameter neck part 1a under the seed crystal 24a and a spherical constriction 1b is subsequently formed under the neck part 1a. At this time, the tips of single crystal supports 23 are opened so as not to come into contact with a constriction 1b during the pulling up.

Abstract: PURPOSE:To grow a thin film on a semiconductor substrate under a decompressed state by a method wherein the positioning jig of semiconductor substrate supporting jig whereon a semiconductor substrate is provided in a decompressed atmosphere or around it. CONSTITUTION:The position of the stopper 7 and the length of a draw-out rod 4 are determined at the normal position, where a boat 5 will be pushed into a reaction tube 1 by a boat loader, in such a manner that the arm 8 of the draw-out 4 will be exactly fit to the stopper 7 located in the reaction tube 1. When the boat loader 5 reaches the normal position, the draw-out rod 4 is placed on the stopper 7 by the vertical or rotating movement of the boat loader 4, and it returned to the position which does not disturb the movement of a hatch 2. Then, the hatch 2 is operated, and the reaction tube 1 is maintained in a decompressed state. The draw-out rod 4 connected to the boat 5 does not move because it is fixed by the stopper 7 even when the boat 5 is going to move by the force generated by the flow of gas produced when decompressed. The growth of a thin film is finished, the hatch 2 is opened, and the boat loader 3 moves out to catch the draw-out rod 4. As the draw-out rod 4 is fixed by the stopper 7, it can be picked out easily.

Abstract: PURPOSE:To enable reproducing in the state of the high coercive force of a recording layer and to stably maintain the domains of a recording layer by applying a magnetic field for reproducing in a direction where the domains stably exist and setting the compensation temp. of the recording layer near the temp. at which the domains rise at the time of reproducing. CONSTITUTION:The recording film 12 is composed of a reading out layer GdFeCo, a shielding layer TbFe and the recording layer TbFeCo. Regions 15 to be irradiated with a laser beam have a temp. distribution when reproducing is executed by rotating a disk in a direction 17. A part of the regions are heated up to the Curie point of the shielding layer or above and the exchange bonding strength of the reading out layer and the recording layer is cut off. Only the magnetization 14 of the GdFeCo in this state faces the direction of an external magnetic field 16 and, therefore, the regions where the exchange bonding strength is shut off are adjusted to reproduce only the magnetization of the regions 18. The reproducing is executed by impressing the magnetic field in the same direction 16 as the direction of the recording magnetic field. The compsn. of the recording layer is so set that the compensation temp. attains about 100 deg.C.
