Title: Method for manufacturing semiconductor device
Inventor: MIZUO YUURI
IPC: H01L21/76
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To suppress etching residue of a polycrystal silicon film, by performing wet-etching process with the use of an etching rate difference between the material used for a cap insulation film and the side wall part of a field shield electrode. SOLUTION: A shield gate oxide film 2 is grown on an Si semiconductor substrate 1, and a polycrystal silicon film 3 and a CVD oxide film 4 are deposited sequentially. Then, lamination films 2, 3, and 4 are so patterned that the Si semiconductor substrate 1 of an element active region 5 is exposed to form a field shield electrode 31, then the field shield electrode 31 is thermal oxidized, so that a side wall axide film part 7 is formed an both sides of the field shield electrode 31. Then, under the condition where the CVD oxide film 4 is etched, wet-etching with hydrofluoric acid is perforned. Since the etching rate of hydrofluoric acid of the CVD oxide film 4 is about 7 times of a thermal oxide film, only the part of CVD oxide film 4 is selectively etched.

Abstract: PURPOSE:To prevent a supplying spool from being carelessly rotated at the time of taking out a film cartridge, with simple structure by changing over the state of a locking means by being linked with the opening/closing action of a cartridge cover. CONSTITUTION:The projecting part 3a of a locking lever 3 is protruded from an outer cover 1, but the projecting part 3a passes a groove, so that when the film cartridge is loaded in a cartridge chamber 19, the film cartridge can be loaded in a state where the rotation of the supplying spool 2 is blocked by the locking lever 3. When a cartridge chamber cover 18 is closed in this state, the cover 18 is abutted on the end part 13c of an interlocking lever 13, and presses it downward against the pressing force of a spring 16. Thus, a releasing lever 12 is rotated to the right, the projecting part 3a of the locking lever 3 is pushed by the arm part 12b of the lever 12, and the blocking of the rotation of the supplying spool 2 can be released by the locking lever 3.

Filed: 1990-10-26
Abstract: PURPOSE:To eliminate the polarization dependence without necessity of eliminating double refraction of respective channel waveguides by arranging a polarization separation circuit and two input waveguides for horizontal polarized light and for vertical polarized light. CONSTITUTION:The wavelength multiple signal light from a transmission line 9 are separated into a horizontal polarization (TE) light component and a vertical polarization (TM) light component by means of a polarization separation circuit 10, and through polarization holding fibers 11, 12 the TE polarization light component and the TM polarization light component pass through the first input waveguide 2 and the second input waveguide 3 respectively, leading to incidence on an input side slab waveguide 4. The light diffuses because no horizontal confinement exists within the slab waveguide, and waves are guided into a plurality of channel waveguide 6. After receiving the required phase difference at an array waveguide, the light is emitted to the output side slab waveguide, and converges in the vicinity of the center of curvature. The converging position is obtained from a different output waveguide 8 based on the wavelength according to the phase difference received at the array waveguide.

Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To provide an infrared microscope in which a polarizer is moved and rotated in an optical path by the slit operation of a variable aperture. SOLUTION: The variable aperture 50 is constituted of a pair of slits 21 movable in a casing 22 in Y-direction and a slit 20 on one hand and a slit 24 with a polarizer on which a polarizer is mounted on the other hand in X- direction. Since an aperture 23 is formed at the center by the movement of each slit, it is possible to limit the field of view of infrared measurement. Since the slit 24 with a polarizer in which a polarizer is mounted on one slit can be moved to the center of the aperture 23, it is possible to observe polarization with visible light by a polarizer by mounting an infrared micro-spectral or visible light polarizer at this time. Since the slit 24 with a polarizer can be rotated together with the casing 22, it is possible to catch information from a sample at the angle of polarization.
