Title: Method for electron beam exposure
Inventor: KOMATSU KAZUHIKO
IPC: H01L21/027
Filed: 1981-01-27
Abstract: PURPOSE:To enable to perform a high-speed patterning by a method wherein, using the clock having fixed frequency, the optimum irradiating time for an electron beam is approximated by the integer-fold clocks. CONSTITUTION:In the method wherein an electron beam is formed by a slit and a patterning is performed by increasing or decreasing the beam irradiating time for every shot, first, beam current density is measured, and a reference irradiation time TS is determined. When basic clock frequency t is 5ns, for example, if the reference irradiation time TS is 100ns, the reference irradiation time TS becomes the integral time of the clock frequency t, and as the dividing width 5% of the amount of variation of the irradiation time is coincided with the clock frequency, the irradiation time can be controlled accurately. When the reference irradiation time TS is 111.1ns, for example, which is not an integral multiple of the clock frequency t, the beam irradiation time is controlled by having the reference irradiation time TS and the amount of variation approximated by integrally multiplying the clock frequency t.

Filed: 1987-01-19
Abstract: PURPOSE:To efficiently clean the eutrophication pollution in a closed type water area by dispersing the deposits of bottom material forcibly into the water so that the polluting components are taken by living matters. CONSTITUTION:An aerator 2 and/or mechanical stirrer 3 is installed to a movable raft-like structural body 1 and a double pipe type contact device having inside cylinders 4, 4' and outside cylinders 5, 5' is provided toward the inside of the water.

Filed: 1991-01-30
Abstract: PURPOSE:To enhance the reliability and productivity of soldering connection by printing solder paste on a connection pattern which connects each kind of semicnductor and electric component in such a fashion that it may cover each of the whole patterns, then heating them at a temperature which exceeds a melting point of solder and selectively forming a solder pattern on said connection pattern.

A specified semoiconductive is fixedly installed to this board 5 on which the solder paste pattern 7 is printed. The solder is molten and electrically connected thereto. When the ogranic solder is heated at a temperature higher than 200 deg.C, the Cu and solder's Sn which form the connection pattern 6 produce a metal compound so that they may be connected to each other. Then low temperaturew solder produces a metal compound in a similay fashion. This construction makes it possible to enhance the solder connection properties and reliability as well.

Title: Light wavelength measuring instrument
Inventor: OGATA TAKAAKI
IPC: G01J3/36
Filed: 1989-01-20
Abstract: PURPOSE:To measure the chirping characteristic of a distribution feedback type laser by converting the fluctuation of wavelength caused by the chirping of the laser into the spatial fluctuation of a light beam with the aid of diffraction grating and moreover into voltage fluctuation with the aid of a photodetector and a differential amplifier. CONSTITUTION:When oscillated light from the distribution feedback type laser is made incident on the diffraction grating 1, the incident light 7 is reflected at an angle in accordance with wavelength and received by the photodetectors 2 and 3. Photoelectric current which is photoelectrically converted is converted into a voltage signal by amplifiers 4 and 5, and voltage difference Vout is detected by the differential amplifier 6. Next, when the oscillated wavelength changes by chirping, a diffraction angle changes and the incident position of the light beam on the photodetectors 2 and 3 changes from a continuous line A to a short dashes line B. A light intensity distributed position changes from C to D. In the case of C, since the apex of the distribution is positioned in the center between the photodetectors 2 and 3, the intensity of the incident light is equal and the Vout is zero. In the case of D, the apex of the distribution is at the position of the photodetector 3, so that the output Vout is becomes a negative value. Therefore, the chirping characteristic of the distribution feedback type laser is obtained by measuring the Vout.
