Abstract: PURPOSE:To perform highly accurate measurement by making it possible to increase the contrast between a light part and a dark part even when there is optical anisotropy, by arranging a polarizer so that a polarizing axis is set on the incident light path of white light in an arbitrary straight line polarizing direction. CONSTITUTION:The white light emitted from a white light source 1 is condensed to the pinhole on a pinhole 3 by a condenser 2 and further converted to parallel light by a collimator lens 4 to become only linear polarized light having the vibration direction of a P- or S-wave component by a polarizing plate 5 and said linear polarized light is incident to the incident point of an object 6 to be measured through the incident window of a condenser 7. The reflected light from the object 6 is guided to a fractionating lens 11 and only the same direction component of the emitted light of each optical fiber 10 among the reflected lights condensed to the condenser 7 is guided to an extracting pinhole plate 12 and a light having a light part and a dark part is amplified by an image intensifier 15 through a collimator lens 13, a plane diffraction lattice 14 and an image forming lens 15 and the intensity of light at every wavelength is detected on a linear image sensor 18. Then, the wavelengths of the light and dark parts are calculated to operate the film thickness of the object 6.

IPC: H03F3/68
Filed: 1990-11-21
Abstract: PURPOSE:To reduce a shock sound caused by the variance of an external NF capacitor by supplying a voltage being a little lower than a bias voltage of a non-inversion input terminal of two differential amplifying circuits for executing power amplification of the same phase signal and an opposite phase signal, to an inversion input terminal only at the time of turning off a bias switch. CONSTITUTION:A sound signal inputted to an input terminal 16 is amplified by a buffer amplifier 5, allowed to branch and outputted as signals of the same phase and an opposite phase, and the respective signals (same phase signal, opposite phase signal) are subjected to power amplification by differential amplifiers 1, 2 and outputted from the same phase output terminal 14 and an opposite phase output terminal 15, respectively. Reference voltage generating circuits 20, 21 generate a little lower voltage from non-inversion input terminals 28, 29 of the differential amplifiers 1, 2, and changeover switches 18, 19 supply a voltage to inversion input terminals 12, 13 of the differential amplifiers 1, 2 only at the time of OFF of a bias switch circuit 22. As a result, the difference of a rise time of the differential amplifying circuit 1 and a differential amplifying circuit 2 caused by an unbalance of the capacity of an NF capacitor 6 and an NF capacitor 7 is reduced, and a shock sound can be reduced by 50%.

Abstract: PURPOSE:To improve a sputtering treatment capacity without the need for lowering and raising the temp. of a heater at every sputtering treatment by isolating a sample treating chamber provided with a target and a sample to be formed with a film and a heater chamber of a sputtering device with a freely openable and closable sluice valve. CONSTITUTION:The sample treating chamber 2 and the heater chamber 3 of the sputtering device are segmented by the freely openable and closable sluice valve 4. The inside of the device is evacuated to a vacuum by opening discharge valves 13, 14 while the sluice valve 4 is held open; thereafter, the heater 8 is heated to a prescribed temp. The sluice valve 4 is then closed and gaseous N2 is introduced from a vent valve 10 into the sample chamber 2 to generate the atm. pressure. After the sample 5 is mounted to a holder 6, the inside of the chamber is evacuated to a vacuum. The sluice valve 4 is opened and the sample 5 is rapidly heated by the heater 8; thereafter, gaseous Ar 9 is introduced into the chamber and a voltage is impressed to a target electrode 7 by a power source 15 to generate plasma. The sputtered film is formed on the sample 5 by the target 7A. The sluice valve 4 is closed at the time of exchanging the sample in the sample treating chamber 2 or exchanging the target 7A and, therefore, the heater 8 can be held lowering the temp. and the need for lowering the temp. and again raising the temp. thereof at every time is eliminated. The working efficiency is thus improved.
