    摘要: An evaporation apparatus comprises an elongated crucible having an upper opening and storing an evaporation material, an electric heater which covers the upper opening of the elongated crucible, generates heat by causing electric current to flow therein for heating the evaporation material stored in the crucible, and has an opening through which the evaporation material which is vaporized by heating can pass through, and a fixing member for pressing and fixing the electric heater onto the elongated crucible. Further, between the fixing member and the electric heater, an angle member having surface portions respectively fitting onto an edge portion of the upper surface and an upper portion of the side surface of the elongated crucible is provided along the longitudinal direction of the elongated crucible. A pressing force from the fixing member is made to exert onto the electric heater via the angle member to bring the electric heater into close contact with the elongated crucible.

    摘要: This invention is based on the problem of achieving the most planar possible phase boundary extending in the horizontal direction between the still molten material and the material that has already crystallized out in a vertical Bridgman crystal-growing furnace or vertical gradient freeze crystal-growing furnace for crystallizing out the semiconductor melt (4) and doing so at a low cost. Therefore, jacket heaters (11, 12) are provided coaxially with the furnace core containing the crucible (6) and measurement devices for determining radial temperature differences in the space between the jacket heaters (11, 12) and the crucible (6), whereby the heat output of the jacket heaters (11, 12) is adjusted so that the measured temperature differences become zero. Thus, at least in the planes in which the measurement devices are located, radial heat transport is prevented and a phase boundary that is not curved is implemented.

    摘要: The method for making a uniform, large-size single crystal of calcium fluoride includes placing a single precursor crystal of calcium fluoride in a tempering vessel provided with a cover; introducing calcium fluoride powder into the tempering vessel and subsequently heating the single precursor crystal, preferably in intimate contact with the calcium fluoride powder, in the tempering vessel together with the calcium fluoride powder for two or more hours at temperatures above 1150null C. to temper the precursor crystal and thus form the uniform, large-scale single crystal of calcium fluoride. The uniform large-sized single crystals of calcium fluoride can be used to make improved lens, prism, light-conducting rod, optical window or other optical component for DUV photolithography, steppers, excimer lasers, wafers, computer chips and electronic devices containing the wafers and chips.

    摘要: A surface-transformation method of forming regions of a second material in a first solid material to control the properties of the first solid material is disclosed. The regions of the second material are formed in the first solid material by drilling holes to a predefined depth and at a predefined lattice position. The holes in the first solid material are then filled with a second material and then the first and second materials are heated to a temperature close to the melting point of the first solid material to spontaneously form the regions filled with the second material and embedded in the first solid material at the desired location. A liquid-phase immersion method or a deposition method may be employed to fill the holes in the first solid material.

    摘要: Group III-V, II-VI and related monocrystalline compounds are grown with a rigid support of a sealed ampoule, carbon doping and resistivity control, and thermal gradient control in a crystal growth furnace. A support cylinder provides structural support for the combined sealed ampoule crucible assembly, while low-density insulating material inside the support cylinder deters convection and conduction heating. Radiation channels penetrating the low-density material provide pathways for radiation heating into and out of the seed well and transition regions of the crystal growth crucible. A hollow core in the insulation material directly beneath the seed well provides cooling in the center of the growing crystal, which enables uniform, level growth of the crystal ingot and a flat crystal-melt interface which results in crystal wafers with uniform electrical properties.
