Title: Semiconductor device and its manufacture
Inventor: INOUE TAKAKO
IPC: H01L23/52
Filed: 1995-03-31
Abstract: PURPOSE: To raise the electromigration resistance by forming the sidewalls, bottom, and top of a first metal wiring layer on a first insulating film on a semiconductor substrate to be covered by a second metal wiring layer, and doing in the same way from a second layer wiring onward. CONSTITUTION: First of all, a first insulating film 202 of a silicon dioxide film is formed on a semiconductor substrate 201. Following this, a barrier metal 203 and a first metal wiring layer 204 are formed by sputtering. Next a first interlayer insulating film 205 composed of a silicon dioxide film is formed by CVD, and holes are formed by photolithography and etching processes. After that, a second interlayer insulating film 206 is formed by sputtering, and a third metal wiring layer 207 is formed by photolithography and etching processes. After this, a second interlayer insulating film 206 is formed on the whole surface by sputtering again. A barrier metal is a little larger than the width of the third metal wiring layer by photolithography and etching.

Title: Apparatus for inspecting semiconductor integrated circuit and method for detecting failure of the same
Inventor: MATSUOKA KAZUYUKI
IPC: G01R31/26
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To easily and early detect a failure of a range switch relay by comparing an actually measured value and an expected value when the optional range switch relay is closed and a predetermined current is sent from a voltage impression part and Judging the presence/absence of the failure. SOLUTION: For instance, when a range switch relay 7 fails to open, no current runs to any of range resistors 11-14. At this time, a constant current source supplies a current of 5 μA thereby decreasing a clamp voltage value to -10 V. In consequence, a potential of a set voltage output part 15 becomes -10 V. When sensing the voltage, a set voltage output circuit 1 judges that a voltage of 0 V set at an output voltage set part 2 is not output, and raises an output voltage from a set voltage impression part 3. However, since no range resistors 11-14 is connected, the potential of the output part 15 does not change. The output circuit 1 increases the output voltage of the impression part 3 to 10 V which is a maximum of the clamp voltage, whereby an ADC input part 6 of a current measurement circuit 5 detects this 10 V.  Since a detection voltage at the normal time is 5 V, the relay 7 is judged to fail.

Title: Surface analyzing method
Inventor: MOCHIJI KOZO
IPC: G01N23/225
Filed: 1994-04-15
Abstract: PURPOSE:To analyze the types and bonding states of atoms in the outermost layer of a specimen surface by radiating multivalent ions so ionized as to have an aiming valence to the specimen while decreasing the speed of the ions. CONSTITUTION:A Si substrate (specimen) 101a is cleaned and put in a specimen chamber 103 of a multivalent ion excitation Auger electron spectroscopic measurement apparatus 102 and the specimen chamber 103 is evacuated. A gate valve 104 between the specimen chamber 103 and a multivalent ion valence separating part (Wien filter) 109 is opened and multivalent ions 5 are radiated to the surface of the specimen 101a. The kinetic energy distribution of the electrons 111 radiated out of the surface of the specimen 101a by radiation of the ions 105 is measured by an electron energy analyzer 112. Since the ions 105 have a large size as compared with light and electrons, in the case the ions are radiated at prescribed decreased speed, the ions can not enter the inside of the surface and react only with the outermost layer of the surface and Auger electrons, etc., are radiated only out of the atoms in the outermost layer of the surface. The types and bonding states of the atoms in the outermost layer of the surface can be thus analyzed by measuring the atoms.

Abstract: PROBLEM TO BE SOLVED: To easily examine an identification mark of a cord with a connector in a state connected as is to a counterpart connector or adapter mounted on a panel screen in a high density, without forming a large-diameter portion on the way of the cord with a connector. SOLUTION: In a state in which a connector 1 of a cord 4 with a connector is connected to a counterpart connector or an adapter, a boot 3 for covering a cord 2 near the connector 1 of the cord 4 with the connector is manually pulled towards the extending direction of the cord 2 or pushed towards the connector 1, so that the boot 3 can be easily detached from the connector 1, and further that the detached boot 3 can be slid along the cord 2. A display 3a is provided at the surface of the boot 3, for displaying an identification mark of the cord 4 with the connector. The boot 3 is removed from the connector 1 by manually pulling only the boot 3, and further is allowed to slide on the cord 2, to be thus moved to a position apart from a panel screen. Consequently, it is possible to read the identification mark displayed on the display 3a of the boot 3.

Patent JP-S563417-A (JP)
Title: Magnetic recording system
Inventor: UCHIYAMA SUMIO
IPC: G11B5/09
Filed: 1979-06-19
Abstract: PURPOSE: To avoid the nonwriting of the control block by writing the discontinuation of the writing signal after detection into the magnetic recording medium and then writing the control block signal of the format showing the data termination.  
     CONSTITUTION: In case the writing signal is discontinued, no-signal detection timer 7 detects the fact that the no-signal state has continued for the fixed time on read/ write signal line 1. Thus timer 7 delivers logic "1". Receiving this logic "1", AND gate 8 delivers "1" of the logic to start control circuit 10. Thus circuit 10 transmits the signal to control (EM) signal generating circuit 11 showing the termination of the data and via signal line 16, thus producing the EM signal of the fixed format. The EM signal is sent to head 2 via line 1, and thus EM signal 30 of the fixed format is written into tape 3. In such way, the nonwriting of the control block can be avoided with a comparatively simple constitution.
