Title: Quantum fine wire device and its manufacture
Inventor: OKAJIMA YOSHIHIKO
IPC: H01L29/12
Filed: 1993-12-16
Abstract: PURPOSE:To form a high mobility quantum fine wire in the direction vertical to substrate surface by a method wherein electrons are efficiently confined in the fine wire by constituting a quantum fine wire device by the quantum fine wire, consisting of a needlelike single crystal, formed on a single crystal substrate using a VLS growth method. CONSTITUTION:An Au layer 2 is placed on a silicon single crystal substrate 1 having (111) surface. When the Au layer 2 is heated up to the melting point of Si-Au alloy or higher in the gas atmosphere containing silicon, an Si-Au alloy droplet is generated on the part where the Au layer 2 is placed. At this time, silicon gradually becomes excessive in the droplet of the Si-Au alloy by the thermal decomposition of gas, a layer is epitaxially grown on the substrate 1, and needle-like crystal 3 is grown along the <111> axial direction in the state wherein an Si-Au alloy droplet 5 is present on the tip part. As a result, electrons can be confined in a fine wire.

IPC: H01L21/3065
Filed: 1988-12-15
Abstract: PURPOSE:To prevent an electrode plate and a wafer from closely adhering for preventing the wafer from falling down thereby augmenting the rate of operation by a method wherein a spot facing is provided on the wafer mounting surface of the electrode plate. CONSTITUTION:Pins 12a-12c for a wafer 6 alignment are formed in three positions on an electrode plate 12 made of quartz material while straight line parts 12d, 12e are formed on both sides of the electrode plate 12. Then, a spot facing 12f is provided on the surface of the electrode plate 12 whereon the wafer 6 is mounted. The spot facing 12f is formed on almost the whole surface excluding the peripheral parts whereon the pins 12a-12c are provided in the depth specified to be e.g. around 0.2mm not to disturb the impression or high-frequency voltage. Through these procedures, the contact space between the electrode plate 12 and the wafer 6 can be saved to relieve the adherence phenomenon during the high-frequency voltage impression. Accordingly, even when the processed wafer 6 is lifted by an arm 11, the electrode plate 12 is not to be lifted up together with the wafer 5 so that the wafer 6 may not fall down due to the falling down electrode 12 in transit. Therefore, the recovery work of the failed down wafer 6 by restoring the pressure in the reaction chamber 12 to the atmospheric air pressure can be eliminated.

CONSTITUTION:When a leaking water detector 10 is operated, an air dew point temperature and an air cooler surface temperature are simultaneously compared and examined by means of a surface temperature detecting device 13 and a dew point temperature detecting device 14. In the case of the surface temperature of an air cooler 1 air dew point temperature, since the generation of dewing water is prevented, when a water leakage detector 15 is worked, it is decided that leakage through the air cooler 1 occurs. In the case of the surface temperature of the air cooler the air dew point temperature, since dewing water is generated, it is decided from a following state after the lapse of a specified time. Namely, in the case of the surface temperature of the air cooler is higher than or equal to the air dew point temperature, water in a drain pot 9 is drained once, it is checked again whether the water in a drain pot 9 is drained once, it is checked again whether the water leakage detector 15 is worked, and when it is worked, it is decided that leakage through the air cooler occurs. When it is not worked, it is decided that dewing occurs. When a dew point temperature is not changed for a long time and an amount of waterdrops flowing over the drain pot 9 is not reduced, it is decided that leakage through the air cooler 1 occurs.

Abstract: PURPOSE:To measure the bus using frequency for each or all of plural devices and to output the measuring result in real time by providing a bus using time totalizing means and a bus using frequency output means. CONSTITUTION:When a device 2a, for example, uses a bus 3, the bus busy mode information received from a CPU 1 is inputted to a bus using time counting means 5 together with the device information corresponding to the number of the device 2a. Thus the means 5 counts the clock pulses inputted during the input of both the information. A bus using frequency output means 7 receives a measuring cycle pulse from a measuring cycle production means 6 and at the same time outputs the count value received from the means 5 as the bus using frequency. Furthermore the means 5 totalizes the bus using time of all devices and outputs this totalizing result. Thus it is possible to measure the bus using frequency for each or all of devices and to output the measuring result in real time.

IPC: G06F15/177
Filed: 1991-12-03
Abstract: PURPOSE:To execute communication between processors connected to communication control units a fault has occurred therein even if the fault occurs in the communication control units of different duplex rings by transitting and receiving a frame by repeating it by the processor provided with the communication control unit in which both systems are normal in the case of a double fault.

IPC: H01L27/092
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To obtain a high melting metal film, especially, a low-resistance gate electrode using a tungsten film by composing a gate electrode being composed on a gate insulating film on a silicon substrate of a titanium nitride film, a tungsten silicon film, and a tungsten film in this order from the side of the gate electrode. SOLUTION: A gate electrode being composed on a gate insulating film 3 on a silicon substrate 2 is composed of a titanium nitride film 5, a tungsten silicon film 6, and a tungsten film 7 in this order from the side of the gate electrode. In this case, although later heat treatment allows the tungsten film 7 to react with the amorphous silicon film 6 to form a tungsten silicide film 61, the tungsten silicide film cannot become the mutual diffusion path of impurities since the tungsten silicide film exists on the titanium nitride film 5. Also, the amorphous silicon film 6 is thinner than the tungsten film 7, thus preventing the increase in the sheet resistance of the gate electrode even when the tungsten silicide film 61 is formed.
