IPC: H01L33/30
Filed: 1985-04-02
Abstract: PURPOSE:To improve the yield rate in a hole etching process and to facilitate the attachment of an ohmic electrode to the back surface, by making it possible to form a window layer thickly so that the composition ratio is uniform and crystal defects are few. CONSTITUTION:A hole 101 is formed in an N-type GaAs substrate crystal 100 by photolithography. An N-type AlGaAs window layer 110 is grown by a liquid phase epitaxial growing method, so that, for example, the Al composition ratio, at which light having a light emitting wavelength of 850mm is not absorbed, is obtained. Then, a P-type AlyGa1-yAs cap layer 120, a P-type AlxGa1-xAs clad layer 130 and an N-type AlyGa1-yAs cap layer 140 are grown. The center of a circular-dot shaped mask for selective diffusion is positioned at the center of the hole, in which the window layer 110 is embedded. Selective zinc diffusion is performed, and a current injecting region 150 is formed. Selective etching of an electrode part is performed with respect to the current introducing part from the back surface side of the substrate 100. Then hole etching is carried out, and the window layer 110 is exposed. A light taking out port 160 is formed and pelletization is performed.

Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To facilitate shoe gap adjusting work by manual operation, so that a shoe gap can be accurately and quickly adjusted to a prescribed value even an unskilled person. SOLUTION: When a lever 12 is turned by force W, by this lever and a strut 14, shoes 3, 4 are opened, to come into contact with an internal peripheral surface of a drum 2. When a gap between an anchor member 7 and the shoes 3, 4 disappears by the rotation of the drum 2, the brake action occurs. In shoe gap adjustment, through a toothed ring 19a, a nut member 19 is rotated in a direction of screwing out a bolt member 18, a shoe gap is decreased. During this time, a double helical tooth 19b climbs over a double helical tooth 20a of a socket member 20, by each screw action corresponding to 1 pitch of both the double helical teeth, extension of an adjusting device is generated. When the shoe gap is decreased to a value corresponding to a height of the double helical tooth, the nut member 19 is disabled from rotating, here when work is ended, by tension of a spring 11, the member 19 is return rotated, both the mountain teeth are brought into close contact.

Title: Manufacture of semiconductor device
Inventor: HIRAIWA ATSUSHI
IPC: H01L21/265
Filed: 1988-03-25
Abstract: PURPOSE:To uniformize characteristics of an MOS transistor, and suppress the deterioration of gate oxide film, by implanting ion after an amorphous conductor or a semiconductor film is formed on an insulating film. CONSTITUTION:Instead of the conventional polycrystalline silicon film, an amorphous silicon film 4 is formed, which is used as a shield layer at the time of E implantation (ion implantation to adjust the threshold voltage of an MOS transistor). The shield layer is necessary to be amorphous at the time of E implantation, and it is allowed that the layer turns into polycrystal or single crystal after the E implantation. In the amorphous silicon film 4, therefore, crystal structure such as the one in a polycrystalline silicon film scarcely exists, so that channeling does not generate at the time of ion implantation. Thereby, the uniformity of the threshold voltage of an MOS transistor can be improved without deteriorating a gate oxide film 3.

Title: Method for measuring strain in flange part of can
Inventor: KII HIRONORI
IPC: G01B5/30
Filed: 1990-03-19
Abstract: PURPOSE:To make it possible to perform direct measurement of local strain when the flange of a drinking water can or the like is formed by using aluminum or a tin plate by sticking a plurality of orthogonal grids whose interval is specified to the flange part of the can, and directly measuring the local strain formed in the machining of the flange. CONSTITUTION:A plurality of orthogonal grids 15 whose interval is 20 - 100mum are attached to a flange part 12 of a can 11 by using bonding agent before the machining of the flange. When the grid interval is less than 20mum, the grids are hard to manufacture, and the cost becomes high. When the grid interval is wider than 100mum, the strain measuring accuracy is decreased. Therefore, the value of 20 - 100mum is adopted. When the measurement is performed, a usable measuring instrument and the like are used, and the strain (e) is computed by the expression e = (grid interval after machining)/(reference interval before machining) X 100%.

Title: Semiconductor integrated circuit
Inventor: ATSUMI SHIGERU
IPC: H01L27/02
Filed: 1990-03-22
Abstract: PURPOSE:To enable an input protective resistor to be hardly damaged by an excessive input voltage and to prevent a large current from continually flowing when an input voltage becomes low after an input protective element is broken down. CONSTITUTION:An input protective element 13 is connected between a signal path which starts from an input protective resistor 10 and terminates at the gate of a MOS transistor TR 12 and a ground potential. When a voltage not so excessive is inputted, the resistor 10 not only functions as a current limiter but also makes the input voltage blunt in waveform, in result the transistor TR 13 is turned ON through a bipolar action to discharge an excessive voltage. At this point, a voltage drop is induced in the resistor 10, an input voltage required for keeping the TR 13 in an ON state becomes high. When an input voltage becomes low after noises are instantaneously added to an input voltage to make the TR 13 break down, the TR 13 is not kept in an ON state and a large current is prevented from continually flowing.

Abstract: PURPOSE:To prevent the formation of a circular hole in the gap between an oxide film and SOG film even when wet etching is performed to form an opening in the films so that the yield of a semiconductor device can be improved by performing high-temperature annealing followed by oxidation on the SOG film after applying an SOG to the surface of the oxide film and performing low-temperature annealing on the SOG film. CONSTITUTION:After forming a gate oxide film 7 on the surface of a semiconductor substrate 1, first-layer polysilicon 2 is formed on the film 7 and oxide films 8 which become side spacers are formed on the side walls of the polysilicon 2. Then a CVD oxide film 3 is deposited on the entire surface of the substrate 1 including the polysilicon 2 and oxide films 8 and a flattened layer (SOG film) 4 is formed on the surface of the oxide film 3. After forming the SOG film 4, the film 4 is heat-treated in an oxidizing atmosphere. Namely, high-temperature annealing followed by oxidation is performed on the SOG film 4 after the SOG film 4 is formed and annealed at a low temperature. Therefore, the yield of a semiconductor device can be improved, because no circular hole is formed even when improper etching is performed.
