IPC: H01L21/22
Filed: 1988-09-14
Abstract: PURPOSE:To uniformly distribute a temperature of on object to be treated by installing a conveyance means used to levitate the object to be treated in the air and to convey it inside a beating and treatment part and outside the heating and treatment part in a noncontact state against a solid body. CONSTITUTION:A semiconductor wafer 1 is fed one by one to a conveyance part 8 of a wafer guide 7. When a gas is blown off from blowoff holes 7b, the wafer 1 fed to the conveyance part 8 is set to a levitated state, and is conveyed on a guide bottom face toward the side of a high-temperature treatment part 9 by gravitation thanks to a downward inclination. Then, the wafer 1 is stopped at the treatment part 9 in a noncontact state, and is heat-treated for a definite duration at the treatment part 9 in a heating and treatment part 4. Then, after this heating and treatment operation, the guide 7 is displaced as shown by a two-dotted chain line in such a way that the conveyance part 6 is set to a downward inclination from the side of the treatment part 9 to the side of a cooling and treatment part 5. By this displacement, the wafer 1 is conveyed in a levitated state from the treatment part 9 toward the treatment part 5. Accordingly, since the wafer 1 is heated and conveyed in the noncontact state, a temperature of the wafer 1 can be distributed uniformly.

Title: Ion beam scan image obtaining method and focusing ion beam device
Inventor: KISHI TADASHI
IPC: H01J37/30
Filed: 1992-08-27
Abstract: PURPOSE:To form an image of change by beam radiation even when a diameter of a focusing ion beam is set small by scanning an ion beam on a sample, detecting quantity of absorption currents flowing through the sample to a scan position, and forming the image. CONSTITUTION:An ion beam 3 is radiated to a sample of an IC4 to be scanned at a specified speed in X- and Y-directions by a scan signal generator 8, a controller 9, and an amplifier 10. The beam 3 loses electric charges on a surface of the sample to be reflected to generate secondary electrons. A current flows from the side of a current measuring amplifier 7 through a sample table 5 into the sample 4 to be measured and amplified by the amplifier 7. A current image, corresponding to beam scan, can thus be formed on a Braun tube of a video monitor 12 by these measurement signals and X-Y signals from the controller 9. An image of change by radiation can also be formed when a focusing ion beam is set to be 350Angstrom  or less.

Filed: 1984-10-31
Abstract: PURPOSE:To reduce damage against a substrate and to keep film thickness of element separating regions uniform, by oxidizing a polycrystalline silicon layer except inside of grooves to form a first silicon oxide film, and by removing the oxide film using diluted hydrofluoric acid solution. CONSTITUTION:Using a resist pattern 23 as a mask, a substrate 21 is etched to form a groove 24. After the pattern 23 and the oxide film 22 are removed, a thermal oxidation film 25 is formed on the surface of the substrate 21. Over the entire face, a polycrystalline silicon layer 26 is deposited, and a silicon layer 26 is filled in the groove 24. The silicon layer 26 is oxidized by hydrogen burning so as to leave the silicon layer 26 in the groove 24, so a first silicon oxide film 27 is formed. The oxide film 27 is exfoliated by using diluted hydrofluoric acid solution. Oxidation forms a second silicon oxide film 28 to form a element separating region 29. Thus damage against the substrate can be reduced and the film thickness of the element separating region can be kept uniform.

Filed: 1983-12-05
Abstract: PURPOSE:To perform reproduction with a little S/N deterioration due to a phase shift by using one light wave separated by a polarization separator as a light wave for a local oscillator when modulated information of a coherent light wave is demodulated. CONSTITUTION:Single polarized wave coherent light from an optical fiber 1 which contains optically phase-modulated information is made into circular polarized light by a lambda/4 plate 2 and this light is separated by the polarization separation device 3 into polarized light waves having mutually orthogonal polarization directions. One is shifted in phase by 90 deg. through a lambda/2 plate 5 to obtain the same polarization direction with the other polarized light wave, and then made incident on a lens 6. The other wave is reflected 10 totally by an optical phase modulator 14 and made incident to the lens 6, but phase-modulated optically by an oscillator 1 at the frequency from an oscillator with optical path length variation. Those two polarized waves incident on the lens 6 are multiplexed and photodetected 7, and a signal of frequency after the optical phase modulation of the optical phase modulator 14 at the frequency of the oscillator 8 is extracted and inputted to a mixer 9. The mixer 9 mixes it with the frequency of the oscillator 8. Consequently, reproduction with good S/N is attained.
