Abstract: PURPOSE:To obtain a grown layer of good crystalization at low temperatures by such an arrangement wherein a single crystal substrate or a semiconductor substrate on which insulation film patterns are formed is placed on a suscepter, and it is put in a vapor growth device, and an epitaxial layer is caused to grow on the substrate by supplying ethyl silicate gas, hydrogen gas and such an amount of chlorine gas of which flowrate is regulated in relation to hydrogen into the device. CONSTITUTION:On an Si substrate 1 of P type or N type, an SiO2 film 2 is selectively formed, and the substrate is placed on a carbon suscepter and this is put in a reaction chamber composing a gaseous phase growing device. Next, as raw material gases, Si(OC2H5)4, H2 and HCl are supplied into the chamber, while the ratio of Si(OC2H5)4/H2 is maintained at about 1% and that of HCl/ H2 at 0.1-1%. After that, the pressure of gas is reduced to about 30 Torr, and the suscepter is heated up to about 700 deg.C and the substrate 1 is irradiated by ultraviolet rays having such wavelength decomposing Si(OC2H5)4. By this method, an Si single crystal layer 3 is caused to grow at only exposed parts of the substrate 1. By this arrangement, growth of layer at low temperature is made possible.

Filed: 1978-11-13
Abstract: PURPOSE: To realize isolation between the two frequency signals which are extremely approximate to each other in a simple structure by deciding the space and the length of the stub so that the line may feature the fixed frequency band and attenuation characteristics and also setting the attenuation polar frequency extremely close to the pass band.

One of these two stubs extends across line 2 in the different lengths, and space l 2  plus lengths l 1  and l 1 ' are decided so that line 2 may feature the fixed frequency band and attenuation characteristics. Thus the BPF can be designed by securing the pass band central frequency plus the attenuation polar frequency of more or less the central frequency. And the sharp rise and fall characteristics can be realized by setting the attenuation polar frequency to the point extremely close to the pass band. As a result, the two frequency signals which are extremely approximate to each other can be isolated in a simple circuit constitution.

Title: Electron beam exposing device
Inventor: TAKAMOTO KIICHI
IPC: H01L21/027
Filed: 1985-06-28
Abstract: PURPOSE:To enlarge the pattern forming region available effectively for exposing the pattern into fourfold or more by a method wherein circular holes are perforated into the acceleration electrode, and moreover, the data on the pattern position of the thin film pattern of the mask are corrected so that the distortion of the image existing in the electronic optical system can be cancelled to form the pattern. CONSTITUTION:High voltage of 10-20kV is impressed between a photo emitter 103 and an acceleration electrode 112 from a high-pressure power source 120. The circular holes are previously perforated into the acceleration electrode 112 and the electrons emitted from the photo emitter are emitted from the acceleration electrode without being interrupted by the acceleration electrode. When the acceleration electrode 112 having the circular holes is used, the field distribution acts as a concave lens by the photo emitter 103 and the acceleration electrode 112 and the pattern formed on a masked substrate 101 has a reduced image when being emitted from the acceleration electrode 112. When an LSI pattern and so forth are formed on the masked substrate 101, the data on the pattern position of the thin film pattern of the mask are corrected to form the pattern. When the pattern on the masked substrate 101 is image-formed by the optical system consisting of the photo emitter 103 and the acceleration electrode 112, the distortion of the image is so contrived as to be cancelled on the image-formation surface.

Title: Cachode absorption method enclosed type battery
Inventor: TERADA MASAYUKI
IPC: H01M4/14
Filed: 1990-05-30
Abstract: PURPOSE:To improve oxygen absorption capacity by placing a substance, having low surface energy and chemical resistance, in a cathode active material or in the vicinity of a cathode surface.
