Title: Back etching device for x-ray mask
Inventor: OKI SHIGEHISA
IPC: G03F1/80
Filed: 1989-06-12
Abstract: PURPOSE:To prevent irreversible plastic deformations or destructions of X-ray penetrating thin films which take place during the etching by applying a pressure through a fluid to a face opposite to the etched face so that the above pressure and a pressure applied to the surface of an X-ray mask etched by an etching solution are offsetted. CONSTITUTION:A pressure applied to the face 6 of an X-ray mask substrate etched by an etching solution 4 is obtained by the product of the density of an etching solution, the height from an etched face to an upper liquid face, and gravitational acceleration. When pressurization liquid 5 is injected in a pressure layer 3, the product of the density of liquid 5, the height up to the upper liquid surface of liquid 5 that is filled in the pressure layer 3, and gravitational acceleration acts as a pressure pressurized by liquid 5. Then, its pressure is transmitted to a gas buffer vessel 2 through a manifold 8 and then, is applied to the face 7 of the X-ray mask opposite to the etched face 6 through a manifold 9. In this way, the etching solution, the density of pressurization liquid, the height of a water surface are regulated so that pressures applied to thin films are offsetted. Irreversible plastic deformations or destructions of X-ray penetrating thin film which take place during the etching are thus prevented.

IPC: H03F3/195
Filed: 1979-11-20
Abstract: PURPOSE:To make simple the constitution and to make stable the operation, by constituting the self-bias circuit with a resistor connected to a low-pass filter which is connected to a gate of EFT. CONSTITUTION:Since resistors 39, 43 are made equal to the characteristic impedance of the line, the microwaves passing through low-pass filters 41, 45 of input and output sides are terminated with nonreflection at the resistors 39 and 43. Since a voltage drop is produced across a resistor 47 through the flowing of the source current from a power supply VCC, the gate of FET37 is biased negative with the source. Input and output matching circuits 31, 34 are formed with high-pass filters capacitors 32, 35 and inductances 33, 36, respectively.

Title: Production of semiconductor device
Inventor: KAMITAKE KAZUTAKA
IPC: H01L21/266
Filed: 1980-10-27
Abstract: PURPOSE:To eliminate the influence of stress strain and to form a diffusion layer of Ga and so on by a method wherein an Si3N4 film is attached onto an SiO2 film in which an opening is provided, and a window is made in the specified region in the opening to inject impurity ions, before being annealed using laser beams. CONSTITUTION:For instance, a CVD oxidized film 25 is formed on the surface of a substrate 21 and an opening is made in a specified region and then a nitrified film 22 is attached onto the whole surface. Next the nitrified film 22 on the opening is photo-etched to provide a window 23. Impurities 26 of, for instance, Ga or Zn which make it difficult to allow the oxidized film 25 to become a mask are injected into the window through the ion-injection method. Subsequently, laser beams such as those of YAG laser are sent out to the ion injected layer 24 to make active the injected ions. By so doing, the crystalline deterioration of the substrate due to abnormal diffusion and an interfacial strain can be prevented during the process of introducing impurities with a greater diffusion coefficient in the oxidized layer, while reproducibility and yield can be improved.

Title: High-speed electric power diode
Inventor: YOOZEFU RUTSUTSU
IPC: H01L29/861
Filed: 1995-06-19
Abstract: PURPOSE: To control dynamic avalanche effect by combining electron irradiation of a specified amount of contribution with the setting of platinum diffusion and carrier lifetime, and thereby producing the recombination center in an intermediate n<-> region and an outer n<+> region. CONSTITUTION: In a diode with carrier lifetime adjusted by electron irradiation, a second maximum value (loop) which is caused by dynamic avalanche due to the generation of charge carriers appears at room temperature. An intermediate circuit voltage of 1200 V is not obtained at room temperature. Temperature- dependent antinode appears at 50 deg.C or below and there is no antinode at 50 deg.C or above. When the diode is subjected to platinum diffusion instead of electron irradiation, there is no antinode. At an operating temperature of 150 V, after maximum countercurrent a current drop slowly occurs, and thus the dynamic avalanche can be controlled; however, this action becomes relatively weak at 150 deg.C. The dynamic avalanche can be controlled by quantitatively combining platinum diffusion and electron irradiation so that the part of electron irradiation is 30-50%, (20-80%).
