Title: Method for casting polycrystalline substance such as silicon
Inventor: HIDE ICHIRO
IPC: H01L31/04
Filed: 1992-07-17
Abstract: PURPOSE:To improve the quality of a cast product, dispense with a heating process at a high temperature, and increase the durability of a cast mold by constantly controlling the crystal-growing direction of the polycrystalline raw material, when the melted liquid of the polycrystalline raw material is solidified in the cast mold. CONSTITUTION:A melted liquid 11a obtained by melting the polycrystalline raw material 11 in a crucible 12 with a heater 13 in an inert atmosphere 10 a is injected into a cast mold 14 under a temperature gradient towards high temperatures in the direction of the arrow T. The injection is not simultaneously performed but gradually carried out, while the injection is synchronized with the crystal-growing velocity (V1) of the melted liquid 11a in the cast mold 14 and while the supply amount of the melted liquid injected from the crucible 12 is controlled by a means such as a means row controlling the heating set temperature of a heater 13. Since a large quantity of the melted liquid is not housed in the cast mold, the crystal does not grow in the transverse direction from the side wall, and only the upward growth of the crystal is constantly performed. Since the constant growth is secured without heating the cast mold at a high temperature, the durability of the cast mold is improved.

Abstract: PURPOSE:To facilitate works by forming a v-shaped groove which is seated across the corner of the stad bottom of a block at the lower side, and thereby forming a spacer having convergently tapered flat surface which pivotally mounts the corner of the stad bottom at the upper side. CONSTITUTION:A spacer 5 consists of a v-shaped groove 6 and a flat surface 7. The spacer 5 is interposed between an upper block and a lower block in such a way that the v-shaped groove 6 of the spacer 5 is seated across the corner of the stad bottom of the lower block. In the second place, a flat surface section which is formed at the corner of the stad bottom of the upper block while being bevelled, is pivotally mounted by the flat surface 7 of the spacer 5, and the inclination of the upper block is adjusted by the flat surface 7 of the convergently tapered spacer 5 in such a way that the spacer 5 is pushed in and out. This thereby permits the self-sustaining of the block to be stabilized, and also enables efficiency in execution to be enhanced.

Abstract: PURPOSE: To produce VLSI for a necessary refresh cycle selective DRAM with a large capacity with a high economical efficiency by arraying DRAMs of a necessary capacity in a rectangle, arranging bonding pads corresponding to different power sources in the middle part, and operating the DRAMs in different modes. CONSTITUTION: Four pieces of 4MB DRAMs individually arrayed in 1st to 4th quadrants make a DRAM of 16MB occupying a small area. In the central part of this VLSI, forty-five bonding pads are divided into two and vertically arranged in a row, and one is selected for a first power source of 4K cycle, the other is selected for a second power source of 2K cycle, and the VLSI becomes a DRAM which works with the first and second options. Further, each peripheral circuit arrayed in the middle part is produced by a common process to different optional modes as far as possible. Thus, an ordinary 4K memory refresh cycle and 2K memory refresh cycle which is predicted to be customary in future becomes a VSLI for a freely selective and highly economical efficient 16MB DRAM.

Abstract: PROBLEM TO BE SOLVED: To provide a Czochralski growth process which can produce single crystalline silicon ingots having uniform heat history from the silicon melt contained in a crucible having the same axis as that of the ingot. SOLUTION: The pulling up speed of the cone end part 30 of the ingot 26 is kept relatively constant comparable to the pulling up speed of the second half of the main body of the ingot. While the end cone 30 of the crystal is pulled up at a constant speed, the amount of heat to be fed to the melt may be increased, the rotation of the crystal is reduced and/or the rotation of the crucible may be reduced whereby the process may be operated more precisely. The second half of the main body of the grown single crystal silicon ingot 26 is relatively uniform in the flow pattern defect and the concentration of the precipitating oxygen in the axial direction.

Abstract: PURPOSE: To enable a cold storage function excellent in cooling efficiency without enlarging the size of a compressor, by having a gas compression system of refrigeration cycle, and providing this refrigerator with a cold storage device to thermally contact with an evaporator inside. CONSTITUTION: A cold storage tank 3 is coupled through a heat pipe 18 to an evaporator 17. An opening and closing valve 19 is installed in the circuit of the heat pipe 18, and a timer 20 to control the operation of the opening and closing valve 19, within the heat pipe 18 opens the opening and closing valve 19 only in, for example, midnight power application time zone.
