Title: Method and device for forming vapor-phase reaction thin- film
Inventor: MOCHIZUKI YASUHIRO
IPC: H01L21/205
Filed: 1983-09-19
Abstract: PURPOSE:To form a reaction product in desired film thickness continuously on a silicon wafer by alternately repeating and executing the formation of thin-films as the reaction product to the silicon wafer and the etching of reaction-product films from an excited-beam entrance window. CONSTITUTION:A reaction vessel 51 is divided into two reaction chambers with beam entrance windows, through which excited beams can be transmitted, by a parting plate 56. Substrates 25 on which films are formed are charged into one reaction chamber. A reaction gas 58 is introduced while heating the substrates 25 up to a predetermined temperature, and excited beams are projected to the substrates 25 through the beam entrance window. An etching gas 59 is introduced into the other reaction chamber without charging any substance. The vessel 51 is turned by a motor 54. When thin-films as reaction products are formed onto the surfaces of the substrates 25, the thin-film as the reaction product deposited on the inner surface of the beam entrance window is removed through etching. Accordingly, the speed of deposition of the reaction products on the substrates 25 does not reduce with the lapse of time, and the reaction products in desired film thickness are formed continuously on the substrates 25.

IPC: H01L27/088
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To form a plurality of kinds of gate insulating films in a simple way in a semiconductor device. SOLUTION: A silicon nitride film 5 exhibiting a high oxidation barrier characteristic is formed selectively on the surface of a silicon substrate 1 by subjecting the substrate 1 to a direct thermal nitriding process or the like. Then, the surface of the substrate 1 having the film 5 selectively formed is thermally oxidized. The thermal oxidation of the substrate 1 allows a first gate insulating film 7 having a different composition and a thinner thickness to be formed in the region where the film 5 is formed, and at the same time, a second gate insulating film 8 which is thick to be formed on the surface of the substrate 1 where the film 5 is not formed. It is in this way that a semiconductor device having a plurality of kinds of gate insulating films is formed.

Title: Image forming device
Inventor: KURODA KOUKI
IPC: G03G15/11
Filed: 1979-12-28
Abstract: PURPOSE:To enable image formation to be carried out even when a converter etc. come to fail in further normal operation owing to a certain reason by providing means of setting conditions of forming electrostatic latent image or developing conditions at predetermined values irrespective of the output of a D/A converting means. CONSTITUTION:After a developing bias control value is integrated, it is applied to the first terminal of a changeover switch SW4. Changeover switches SW2, SW3, SW4 are provided in order to change over potential controlling with a CPU2 and circuits for keeping the developing bias at a predetermined value by flowing reference current to a charger without going through the CPU2. This changing-over makes it possible to flow the reference current to the charger and keep the developing bias at the predetermined value even in such a situation when the CPU2 is disabled on account of a certain accident. Hence, even if the circuits before the D/A converter go out of order, the image formation may be executed and the excessive degradation of the image quality may be prevented. Here, the CPU1 denotes a microcomputer for sequence controlling.

Abstract: PURPOSE:To prevent the exfoliation between a heat insulating layer and disk substrate by forming an information medium layer to one face of a disk-shaped transparent substrate and forming resin layers having the heat resistance specified in the thermal deformation temp. between the transparent substrate and the information medium layer and onto the information medium layer. CONSTITUTION:The layers 9, 11 consisting of the resin material having the heat resistance of >=200 deg.C thermal deformation temp. are formed in place of the heat insulating layers consisting of an inorg. material on both sides of the recording medium layer 10. The recording medium layer 10 is quickly heated and quickly cooled to form an amorphous state of a low reflectivity by which information bits are formed when laser light of a high power density throttled down to about 1mum spot diameter is projected at the time of recording. The recording medium layer is slowly heated and slowly cooled to form a crystalline state of a high reflectivity by which the information bits are erased when the laser light of the low power density formed to an elliptical shape at the time of erasure. The recorded information bits are read by the laser light of the power substantially lower than for recording and erasure at the time of reproduction. The exfoliation and microcracks by the environmental change during the preservation of the disk and the heat of the laser light are thereby prevented.

Title: Optical shaping method
Inventor: MURATA KATSUHIDE
IPC: B29C35/08
Filed: 1988-07-13
Abstract: PURPOSE:To make a high-precision model which is free from a crack and hardly possesses a dimensional error due to shrinkage, by a method wherein curing is performed so that uncured photosetting resin is left behind partly on a part to which light is applied, the light is applied to an exposed part from the surface of a liquid out of a cured matter containing the uncured resin and is in the middle of shaping and the photosetting resin remaining uncured is cured. CONSTITUTION:A height of the surface of a liquid of photosetting resin is set up so that the upper part of a cured matter 24 in the middle of shaping is exposed from the surface of the liquid and light is applied to the photosetting resin in a vessel 11. In this instance, curing is performed by changing strength or a scanning rate of light flux 14 so that uncured resin remains behind partly on the irradiating part of light. Then shrinkage stress due to cure is dispersed and absorbed by an uncured part, which is made into a primary cured matter 25 where the shrinkage stress hardly occurs. Then the residual uncured resin is cured by applying the light flux 14a, 14b to an exposed part 25a from the surface of the liquid due to a rise of a base 21 out of the primary cured matter. Even in the second curing process, the shrinkage stress hardly occurs so long as the uncured resin exists on the circumference at the time of spreading of cure. The shrinkage stress is generated in an extremely short period of time at the last stage of the cure and shrinkage stress itself becomes extremely little.
