Title: Production of single crystal of volatile compound semiconductor
Inventor: TATSUMI MASAMI
IPC: H01L21/208
Filed: 1985-01-19
Abstract: PURPOSE:To prevent precipitation of a volatile element on the end face of the high-temperature side of transparent quartz rod, and to observe clearly the conditions of single crystal growth, by attaching a cap having a transparent quartz window through a heat insulating material to the end face of a high-temperature side of the transparent quartz rod, and inserting the rod into a furnace in a state wherein the gap between the end face and the cap is made air-tight. CONSTITUTION:The cap 22 having a transparent quartz window part having good absorption infrared radiation energy is attached through the quartz rod 17 and the heat insulating material 20 to the end face of the transparent quartz rod 17 at the side inserted into the container 16, for observing the conditions of crystal growth in the crystal growth container 16. The gap 21 between the end face of the quartz rod 17 and the cap 22 is constructed in an air-tight structure, so that the atmosphere gas 18 in the container is not sent to the gap. When the observing device having the structure is fixed to the container 16 and crystal growth is started, the atmosphere gas 18 is filled with the component vapor of volatile element of crystal raw material which is passed through the liquid sealing agent 12 and vaporized. But the cap 22 absorbs infrared radiation energy and kept at high temperature, so component vapor of the volatile element will not precipitate, and the conditions of crystal growth can be observed without causing clouding.

Inventor: OKANOE ETSUO
IPC: G02B1/10
Filed: 1993-01-20
Abstract: PURPOSE:To prevent yellowing phenomenon and dispense with the use of a solvent toxic to environments such as fluorocarbon by making a silane compound gas react with an inorganic coat film in vacuum or the atmosphere. CONSTITUTION:A silane compound gas is reacted with an inorganic coat film mainly containing SiO2 in vacuum atmosphere or the atmosphere. After forming the inorganic coat film in a vacuum chamber, for example, the silane gas is introduced thereto and reacted with it. Therefore, characteristics of the inorganic coat film and the surface are changed. By using the silane compound having a hydrophobic group, in this way, yellowing by water can be prevented, water resistance of the film can be improved, and reduction in adhesion by water can be prevented. Further, according to a reduction in abrasive coefficient, wear resistance of the film is improved. The use of a diluting solvent for film thickness regulation and a washing solvent, for example, fluorocarbon, to react the gas silane compound is not required.

Filed: 1984-01-23
Abstract: PURPOSE:To make errors small, by measuring spectral heat radiation having wavelengths in three colors or more, assuming the spectral heat emissivity of each wavelength, obtaining the approximate expression of the emissivity, obtaining a temperature, at which the error between both spectral heat radiations is the minimum value, and determining the temperature as the temperature of a sample. CONSTITUTION:The temperature of a sample 2 in a vacuum container 1 is measured by a radiation thermometer 4 through a vacuum window 3. At first, the heat radiation from the sample 2 is divided into wavelengths lambda1, lambda2...lambdan in three colors or more by a spectroscope 5. Then, spectral heat radiations L1, L2... Ln are measured by a detector 6. The curves of the spectral heat emissivities are approximated by a polynominal in the mth order of the wavelength lambda. By this approximate equation, approximate spectral heat radiations Lci are obtained at various temperatures. They are compared with the actually measured spectral heat radiations L1...Ln. The temperature, at which the sum of the squares of the errors becomes the minimum value, is determined to be the temperature of the sample 2.

IPC: F25D11/02
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To prevent an erroneous setting of a range of applied temperature from being performed even if an output voltage of a variable resistor shows a certain fluctuation. SOLUTION: An output voltage Sv of a variable resistor is varied in response to an operation of an operation knob. A micro-computer 30 inputs this output voltage Sv and if the input voltage is increased or decreased by a range of predetermined voltage or more, it is acknowledged as a temperature setting voltage. A cooling temperature is set from an application temperature range of low temperature side or an application temperature range at a high temperature side in response to this acknowledged voltage. When this acknowledged input voltage exceeds or is lowered than the predetermined reference voltage, the set temperature is changed over from an application temperature range at the low temperature side to the application temperature range at the high temperature side or vice versa.
