Title: Manufacture of semiconductor device
Inventor: KUBO TORU
IPC: H01L21/768
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To enable cost reduction and flattening, by forming a metal film into a metal film plug or a metal wiring by using a polishing process and a wet etching process. SOLUTION: A metal film 6 is buried in a hole formed in an oxide film 3 on a semiconductor substrate 1, and a metal film plug 9 is formed by a CMP method and a wet etching method. As the metal film 6 used in this case, a W film formed by a CVD method or an Al alloy film or a Cu alloy film which are formed by a sputtering method or a plating method is preferable. In a CMP method, it is preferable that abrasives containing polishing particles which selectively act on the metal film 6, e.g. alumina particles are used. It is preferable that hydrofluoric aqueous solution or its vapor is used for etching liquid used in a wet etching method. In the above method, etching is performed with aqueous solution used in the conventional case, so that cost reduction is enabled.  Protrusion of the metal film plug 9 after the CMP method is performed can be restrained, so that excellent flatness can be obtained.

Title: Light signal detection element
Inventor: KAWASAKI TAKEHIKO
IPC: H01L39/22
Filed: 1989-10-04
Abstract: PURPOSE:To eliminate the loss of current and improve detection efficiency of signal by enabling an electrode for applying voltage which is provided at a light signal input part and/or the electrode for detecting signal which is provided at a signal detection part to consist of a superconductive material. CONSTITUTION:A band-shaped superconductor 1 and a superconductive electrode 6 are produced at both edges. Then, an MgO film is formed at the center of the band-shaped superconductor 1 for forming an insulation layer 2 and a CdS film is formed on it as a signal input part 3. This detection element is placed inside liquid nitrogen for cooling and Ar<+> laser light is irradiated onto the signal input part 3 consisting of the CdS film. In this case, when a voltage of 10V is applied to an electrode 7 on the CdS film which is the signal input part, current flowing through the superconductor 1 changes corresponding to the ON/OFF of the laser light and current drops by 50% in the ON state where no laser light is irradiated compared with the OFF state where laser light is not irradiated. It indicates that a photocurrent is generated at the CdS film due to the Ar<+> laser light and the resultant magnetic field was detected by the superconductor 1.

Title: Data processing method for material test
Inventor: MAYUMI TAKAAKI
IPC: G01N3/08
Filed: 1986-10-29
Abstract: PURPOSE:To obtain an accurate strain value by processing data while regarding the sum of the distance GL between grippers before the start of a test and the movement distance of a gripper until the slack of a test-piece such as yarn is eliminated, as the initial length of a test piece. CONSTITUTION:The distance GL between the grippers 1 and 2 before the start of the test is registered in the control part of a material testing machine. The gripper 1 is moved in a tension direction until the slack of the yarn is eliminated. The elimination of the slack of the test-piece is detected from the loading of the test-piece exceeding a constant value. At this time, the movement quantity of the gripper 1 is stored as DELTAGL in a memory. Then, a characteristic value, e.g. maximum loading point is detected and the movement quantity of the gripper 1 at this time is recorded as the elongation DELTAE of the test-piece 3. When data processing is performed at the end of the test, GL and DELTAE are used to find the strain value from an equation. Thus, the accurate strain value is obtained.

Title: Radio local area network
Inventor: SUNAGA TERUMI
IPC: H04W74/08
Filed: 1991-10-05
Abstract: PURPOSE:To prevent the throughput of data transmission in a LAN from being lowered by directly transmitting a signal by radio between terminal side transmission equipment at a transmission side and that at a reception side when their positions are within a radio transmission feasible area. CONSTITUTION:Radio transmission/reception means are provided at network side transmission equipment 1 that is a station of a radio LAN and a terminal side transmission equipment 2 connected to a terminal 5. The signal can be transmitted on a radio transmission line between them when the positions of the equipment 2 connected to the terminal 5 from which the signal is delivered and the equipment 2 connected to the terminal 5 that is the delivery destination of the signal are within the radio transmission feasible area. Therefore, the signal is not passed on a transmission line consisting of the equipment 1 and a LAN medium 3. Thereby, it is possible to prevent the throughput of the data transmission in the LAN from being lowered without increasing latency time in signal transmission even when the number of terminals connected to the LAN is increased.
