Inventor: TANAKA SHOJI
IPC: G03F1/68
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a mask blank for X-ray exposure with which the production of a mask for X-ray exposure having high quality is possible and a process for producing the same. SOLUTION: This mask blank 1 for X-ray exposure has at last a silicon substrate 10 for forming a frame, a transmissive supporting film 13 which allows the transmission of alignment light and X-rays and is formed with X-ray absorbers in a pattern form a antireflection film 12, 14 for the alignment light which are disposed on both surface of this transmissive supporting film and is used for producing a mask for X-ray exposure. The transmissive supporting film and the antireflection films disposed on both surfaces thereof are formed by continuous film formation by a vacuum chemical vapor growth method within the same chamber.  Since the respective films are formed by the continuous film formation, there is not possibility that the moisture, oxygen, dust, etc., in the outdoor air adhere to the film surfaces and the particles occurring in such dust, etc., hardly exist within the transmissive supporting film and the antireflection films, the mask for X-ray exposure having the high quality is produced by using the mask blank for X-ray exposure.

Title: Semiconductor device
Inventor: MITAKE KENJIROU
IPC: H01L23/50
Filed: 1985-12-06
Abstract: PURPOSE:To eliminate the immersion of moisture from externally by forming a swelled portion swelled in thicknesswise direction and in perpendicular direction to the thicknesswise direction at a lead portion of a resin-sealed lead frame. CONSTITUTION:A part of a portion disposed in a sealing resin 6 of each lead 2 becomes a swelled portion 2a swelled at its periphery. Since the leads 2 and the resin 6 are the same temperature and the resin and the metal leads have weak affinity, a small gap 7 is formed between both. Since the metal leads 2 have larger expansion coefficient than the resin 6, the leads 2 are pulled in a direction secured b itself. Since a perpendicularly bent portion exists at the inner end of the lead, when the lead 2 is pulled toward a pellet to move the swelled portion, a gap between the swelled taper of the pellet side and the resin is eliminated to prevent moisture from immersing from the exterior by this portion.

Title: System for extending cache memory chip
Inventor: NISHIDE KOICHI
IPC: G06F12/08
Filed: 1987-10-31
Abstract: PURPOSE:To improve the high-speed performance and to decrease the hardware quantity by adding previously a circuit into a cache chip to attain the expansion properties. CONSTITUTION:A circuit is previously added into a cache memory chip 1 to attain the expansion properties. A chip selection signal generating circuit of a control logic 11 produces and supplies a chip selection signal CS so that either one of chips 1 forming a cache becomes active based on the signals received via input pins SL0, EP1 and EP2 for setting areas. The chip 1 can serve as a cache only when the signal CS is active. While a data line has a high impedance when the signal CS is inactive. In such a constitution, no external decoding circuit is required even though plural chips 1 are needed. Thus system working speed is increased.

IPC: H01L27/04
Filed: 1992-10-14
Abstract: PURPOSE:To provide a method for the manufacture of semiconductor devices which prevents poor coverage of wiring layers in forming them on a gate electrode through contact holes, and which thereby prevents the degradation in element performance and reliability, improves the yield and reduces the manufacturing cost. CONSTITUTION:An interlayer oxide film 20 is deposited on the entire surface, and subsequently, an storage electrode 22, source and drain electrodes 23a and 23b are simultaneously formed in the DRAM cell and peripheral circuit regions. A silicon nitride film 24 is deposited, and then an opposed electrode 25 is formed in opposition to the storage electrode to obtain a stacked capacitor. The silicon oxide film 24 is removed from a gate electrode 15 in the peripheral circuit region by etching using the opposed electrode 25 as a mask. This prevents the silicon nitride film from being flawed in contact holes on the gate electrode 15 when the surface of the gate electrode 15 is subjected to light etching in subsequent processes.

IPC: H02B13/02
Filed: 1997-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a gas-insulated switching device with a small size and installation area. SOLUTION: Circuit breakers 5 are arranged on one lateral side of main buses 1, 2 and along them. A first branching bus 31 is extended horizontally from one main bus 1L to the side of the circuit breakers 5. By extending the branching bus 31 from under the main bus 1L, it is passed under the main bus 1L. By using a down bus 11 and a connection bus 12, another main bus 1R is made to reach a position just below the branching portion of the main bus 1L and the branching bus 31 to extend a second branching bus 32 from the position along under the first branching bus 31. Making the two branching buses 31, 32 fall in their courses, they are connected with the respective leading portions of the circuit breakers 5.  As a result, reciprocating the two branching buses 31, 32 in the minimum distances between the main bus 1 and the respective circuit breakers 5 arranged on the lateral side of the main bus 1, the branching buses 31, 32 are shortened to reduce the size of a gas-insulated switching device and its installation area.
