IPC: H01L21/66
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To enhance a voltage measuring accuracy by calculating and calibrating a conversion factor under the same state as voltage measurement. SOLUTION: A probe 21 is held under the same state as it is during measurement, a reference electric potential VS1 is applied to the transparent conductor film 213 of the probe 21, and periodic test signals TS are supplied to a sample 10. Under these conditions, a laser pulse beam is generated in synchronization with a clock ϕwhich is asynchronous with a test clock ST, a polarized state detection signal S is obtained, a reference electric potential VS2 is applied to the transparent conductor film 213, and a test signal TS is supplied to the sample. Under these conditions, a laser pulse beam is similarly generated to obtain a polarized state detection signal S, and the addition average value AS1 of the polarized state detection signals when the reference electric potential VS1 is applied to the transparent conductor film 213 is calculated.  Then the addition average value AS2 of the polarized state detection signals when the reference electric potential VS2 is applied to the transparent conductor film 213 is calculated to calculate a conversion factor α=(VS2-VS1)/(AS1-AS2). The test clock ST or its multiplication may be used in place of the clock ϕ.

Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a ceramic circuit board, by which electrical short circuits can be easily prevented using a simple constitution and to provided a method for manufacturing the ceramic circuit board. SOLUTION: Since first and second convex parts 21 and 22 have a thickness of 20 μm-40 μm, their thickness is equal to or larger than that of burrs 23 and 24 respectively generated at sections 25 and 26. Accordingly, when resistor paste is printed on the surface layer of a glass ceramic multilayer substrate 10, the printing plate can be protected surely, the printing plate can be prevented surely from being damaged by the burrs 23 and 24, and electrical short circuits can be prevented surely. Further, since the first and the second convex parts 21 and 22 are formed by partially increasing the thickness of a conductor wiring layer, the first and the second convex parts 21 and 22 can be formed easily on the conductor wiring layer. Consequently, electrical short circuits can be prevented easily using a simple constitution.

Filed: 1986-11-19
Abstract: PURPOSE:To improve the thermal stability of a resist pattern by making a treatment chamber airtight with a stage on which a substrate is placed and by treating the resist pattern of the substrate surface with heat while directing ultraviolet rays to the substrate surface in situations where the inside of the treatment chamber is depressurized. CONSTITUTION:As a treatment chamber S is evacuated, for example, at a pressure of 30 Torr by using a vacuum pump 15, a shutter 25 opens after a nitrogen gas N2 is supplied to the treatment chamber S through an inactive gas supply pipe 17 as well as an inactive gas supply passage 16 and as ultraviolet rays are directed to a resist pattern of the substrate W surface under reduced pressure, the resist pattern is treated by heat. In this way, the resist pattern can be treated by heat as the ultraviolet rays are directed under reduced pressure to the resist pattern which is formed at the substrate; besides, its control under respective conditions is so easy that this approach permits the resist pattern to exhibit an excellent thermal stability.

Filed: 1990-10-17
Abstract: PURPOSE:To obtain an vortex flow blower in which the air blowing resistance is small and noise is reduced, by installing an insertion pipe which is shorter than the length of an air blowing passage, in the air blowing passage in a muffler. CONSTITUTION:An expansion chamber 23 on the periphery of an air blowing passage 14 is filled with a noise absorbing material 15, and a pipe 16 is installed at a part of the air blowing passage 14, and the length L1 of the air blowing passage in a muffler 8 and the length of an insertion pipe 16 are set in correspondence with the noise generation state. Accordingly, the noise of an vortex flow blower which is generated by the turning flow in a blade wheel 2 and an air blowing passage in a casing is reduced by the resistance in the case where a sound source passes through the noise absorbing material 15. Further, when the noise source in the air blowing passage 14 is reflected randomly in the expansion chamber 23 surrounded by the wall in the muffler 8 and the insertion pipe 16 and returned into the air blowing passage 14, the reflection noise and the incidence noise in the air blowing passage 14 form loop parts, and the phase is reverse each other, the noise pressure level in the muffler 8 can be reduced drastically.

Abstract: PROBLEM TO BE SOLVED: To provide an inductor element which can prevent an increase in wiring resistance in the case where a high frequency current is allowed to flow. SOLUTION: This inductor element is provided with a lower wiring layer made of a metallic film 103 and a spiral upper wiring layer having a plurality of metallic films 111, 121,..., 131, and 141 which are connected with each other through via holes 113 123,...,133, and 143 filled with a conductive material, in the state where insulation films 112 122,..., 132, and 142 are interposed, and the lower and upper wiring layers are connected with each other through a via hole 105 at all portions but a portion where they cross. Thus, since the upper wiring layer is formed by a plurality of laminated metallic films, the wiring layer can be made large in thickness without limitation of process and the wiring resistance be reduced.  Further, the film thickness of every metallic film is made approximately two times the surface depth at the working frequency, allowing a current to flow in almost all areas of section of the wiring layer and reducing the wiring resistance in high frequency.

Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To surely judge the authenticity of an object to be identified by erasing the magnetic noise of a true object to be identified and magnetism formed at a counterfeit object to be identified and then detecting and amplifying magnetic information so as to compare with a prescribed reference value. SOLUTION: Magnetic noise generated in the magnetic information zone of an authentic negotiable value medium 7 and magnetism in the magnetic information zone formed in a counterfeit negotiable value medium 7 are erased by the magnetism of a magnet 1 arranged before a magnetic detection means 2 for the reason that all the magnetic polarities are made opposite to the magnetism of the magnet 1. To the contrary, the primary magnetic of the magnetic information zone given to an authentic negotiable value medium is not erased. Then, an output value which is obtained by amplifying an output value from the means 2 along the magnetic zone of the medium 7 whose magnetic noise is erased by the magnet 1 (a pulse width A1 measured by a judging means 5) and a reference value A0 previously set in a reference value setting means 6 are compared with each other.  Consequently, the authenticity of the medium 7 is surely judged.

Filed: 1989-10-27
Abstract: PURPOSE:To reduce the reflection of an ultrasonic wave and to decrease fluctuation of a pulse peak by forming opposed ultrasonic wave reflecting surfaces on the piezoelectric mounting surfaces of an optical medium in a wedge-shaped or semicircular sectional shape or in an ultrasonic wave scattering surface. CONSTITUTION:When an ultrasonic wave reflecting surface is formed in a wedge shape (b), it is so formed that reflected waves become reverse phases to one another from the upper and lower parts of the reflected surface while monitoring the level of the reflected wave. Accordingly, the shape of the reflecting surface become delicately asymmetrical at the upper and lower parts, an ultrasonic wave interfering region 7 is reduced, the reflected wave is not almost introduced into a laser beam region 5 and weakened each other. Thus, reflection except the reflecting surface is very small, and an influence to a laser beam is extremely small. The reflecting surface which is formed in a semicircular shape (a) or in a slit C has a similar effect. In this manner, the influence of a reflected wave from the reflecting surface to a laser beam is small, and the fluctuation of a pulse peak can be reduced.
