Abstract: PURPOSE:To improve the integration of a semiconductor device by composing at least part of silicide of high melting point metal, and heat treating the semiconductor device formed with the silicide on the semiconductor at the temperature of specific range, thereby enabling a self-aligning and forming method. CONSTITUTION:The surface of a P type silicon 1 is, for example, oxidized, e.g., in a thickness of approx. 1mum, the part is then selectively etched, again oxidized, for example, at approx. 1,000Angstrom , thereby forming an element. Then, Mo-silicide is bonded, for example, on the overall surface in a thickness of approx. 3,000Angstrom . After a thin film is formed, it is selectively etched, thereby forming a gate electrode 2. Subsequently, with the electrode 2 as a mask silicon oxide of 1,000Angstrom  is etched, n type impurity such as phosphorus is diffused to form source and drain regions 3, 4. In this case, a gate electrode is lowered by its specific resistance. Dioxidized silicon film 5 is bonded in a thickness of approx. 1mum by, for example, utilizing chemical reaction on the overall surface, densified, and selectively etched, thereby opening holes 6-8 for producing source, drain and gate electrodes. The Mo-silicide film is again formed on the overall surface, selectively etched to form electrodes 9-11, and then heat-treated at 800- 1,000 deg.C.

Filed: 1985-04-25
Abstract: PURPOSE:To improve the responsiveness to a target value, to obtain an exact time average power value and to make possible the accurate control of an electric power supply quantity by detecting the integrated value of one cycle of the supply power waveform in a power detecting part. CONSTITUTION:A zero cross signal ZC which resets the integrated value is supplied to an integrator 36A outputs a saw tooth wave signal SW. The respective values of a supply voltage signal V, supply current signal I, instantaneous supply power signal W, integrated supply power signal F, max. integrated supply power signal Fm and phase control signal PC are made smaller (larger) than standard values when the supply current to an electrical heating element 14 is smaller (larger) than the target value. The pulse width of a gate trigger pulse GP is then made longer (shorter) than the standard and the firing angle thetaincreases (decreases). The values are therefore so controlled as to follow up the target values, by which the supply of the desired power to the element 14 is made possible regardless of the variance in the resistance value Rx of the element 14 and the quality of the heating is improved.

Abstract: PURPOSE:To remove dust from a sample automatically by using a combination of a dust detecting technique with radiation of rays of light and a gas spraying technique. CONSTITUTION:A light source 1, diaphragms 2, 5, lenses 4, 6, a light detector 7 and a nozzle 11 are arranged above a movable block 9, and the detector 7 is connected to a valve 13 through an amplifier 12 and a valve-opening signal generating circuit 14. In this arrangement, the light 3 emitted from the light source 1 is condensed by the diaphragms 2, 5 and lenses 4, 6 to be radiated onto a sample 8, such as a mask, placed on the movable table 9. When dust sticks to the sample 8, the light is scattered and dected by the light detector 7. An electric signal outputted from the light detector 7 representing the scattered light is applied to the valve- opening signal generating circuit 14. When the signal inputted into the circuit 14 is larger than the reference electric signal, the valve 13 is opened. As a result, a compressed gas is jetted from the nozzle 11 to that portion of the sample 8 which is irradiated by the light, so that the dust sticking to the mentioned portion of the sample 8 is blown off.

IPC: A61B3/10
Filed: 1989-04-12
Abstract: PURPOSE:To measure a diameter of a blood vessel in a fundus instantly with good accuracy by discriminating differences in travel speeds of blood cells in the fundus by using speckle signals so as to identify a blood vessel part in the fundus and further to measure the diameter of that blood vessel. CONSTITUTION:Speckle lights are received by a CCD 43 and output signals from the CCD 43 are sent to a signal processing part 44. Blood vessel discriminating signals are found out by the signal processing part 44, and put out as digital signals after A/D conversions. In an operation part 45, a blood vessel part is identified from the digitalized blood vessel discrimination signals and a diameter of the blood vessel is found out by operations. This diameter of the blood vessel is displayed in a display unit by an output part 46. In case that travel speed of blood cells in a living tissue is fast, an output becomes small by an averaging effect due to accumulation time of a photoelectric transducer, because the variation in intensity of speckle light is very large. On the contrary, the decrease in output is small in case of slow traveling speed. The blood vessel part is, therefore, recognized by discriminating differences in the output strength, a width between both edges of an image of the blood vessel is measured and a diameter of the blood vessel is operated instantly with good accuracy.
