Filed: 1988-10-24
Abstract: PURPOSE:To provide a beam with uniform density by actuating a drawout electrode after thorough mixing in a bucket chamber by means of thermal motion. CONSTITUTION:At the outlet from a microwave discharging chamber 2, a common bucket chamber 6 is furnished to encapsulate ions with a cusp mag. field as a wider space, and an accelerating electrode 7 and a decelerating electrode 8, which are connected commonly with the outlets from ion sources A-C and which serve for drawing out of ions, are furnished at the outlet from the bucket chamber 6. Accordingly microwave is given to the ion sources A, B, C to result in formation of a coil 3 resonance mag. field, and when gas to be ionized is introduced into the microwave discharging chamber 2, ionized ones go out to wider bucket chamber 6 to make heat motion therein freely, and upon thorough mixing for uniform distribution, are drawn out by the accelerating electrode 7 and decelerating electrode 8. Thus uniform ion beam is obtained having the same density.

Title: Method for plating semiconductor wafer and apparatus therefor
Inventor: HONGO AKIHISA
IPC: C25D7/12
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely embed the inside of micrgrooves and microholes with plating by intermittently subjecting the surface of a semiconductor wafer under electroless plating to reverse electroplating. SOLUTION: Electrolessplating is started on the surface of the semiconductor wafer 100 and copper plating is started. Next, voltage is impressed between the semiconductor wafer 100 and a minus electrode plate 30 in the stage the plating grows to a prescribed thickness, by which the reverse electroplating is executed only for the instantaneous short time. At this time, the currents concentrate near to the inlets as compared with the deeper side of the microgrooves and the microholes and, therefore, the plating near the inlets of the microgrooves and the microholes dissolves more and the plating on the deeper side dissolves less. The electroless plating is continued as it is after the end of the reverse electroplating. The intermittent and instantaneous reverse electroplating is repeated every time the plating grows for the specified time.  Since the microgrooves and the microholes are so constituted as to be completely embedded with the plating from the deeper side thereof, the sure embedment thereof with the plating is made possible.

Title: Phase modulation type optical fiber gyro
Inventor: ONO KOZO
IPC: G01C19/00
Filed: 1984-12-21
Abstract: PURPOSE:To take an accurate measurement stably by performing synchronous detection on the basis of the excitation frequency of a phase modulating element as a reference frequency, calculating the phase and magnitude of the actual oscillation of the phase modulating element and performing synchronous detection, and carrying out feedback control over an excitation level. CONSTITUTION:When the phase modulating element 54 is driven at a specific excitation frequency, light outputted from an optical fiber 50 is phase-modulated. A synchronous detector 64 which performs synchronous detection by receiving the output of a photodetecting element 60, on the other hand, performs synchronous detection by receiving a reference signal which has the phase and frequency of the actual oscillation of the element 54. The synchronous detection is attained even if the resonance frequency of the element 54 is detuned from the excitation frequency owing to temperature variation and the actual oscillation becomes out of phase with the excitation frequency. Further, a phase modulating element driving circuit 68 also receives the reference signal from a pickup electrode and controls the degree of modulation so that its level becomes constant. Therefore, even if the resonance element 54 makes a step out owing to temperature variation and the degree of modulation varies, the actual degree of modulation for light propagated in the optical fiber 50 is held constant.

Title: Testing method for semiconductor integrated circuit
Inventor: SUMINO YUTAKA
IPC: G01R31/28
Filed: 1986-11-11
Abstract: PURPOSE:To easily execute highly accurate measurement by forming an exclusive test-only output having larger driving force independently of an original output, connecting the exclusive output to a LSI tester and measuring a propagation time. CONSTITUTION:An output from a inverter 4 is branched and the branched output is transmitted to the test-only output 3 through an output buffer 5. Since the branched output is passed through the circuit 5, capacity driving a load is larger than an output 2, i.e. even if an output is connected to a tester through a transmission line having large capacity, a waveform is not weakened by the capacity. The output impedance of the circuit 5 becomes smaller than the intrinsic output 2. Thereby the waveform is not weakened even by a transmission line to be a capacitive load. Consequently, a semiconductor integrated circuit performance test which may have a result approximate to a practical using state can be attained. Thereby highly accurate measurement can be easily executed.

Title: Delay circuit
Inventor: KUWABARA SUMIO
IPC: H03K5/133
Filed: 1987-10-23
Abstract: PURPOSE:To generate a delay signal similar to that by other circuit on the same semiconductor substrate by increasing number of inverter stages connected in series through the nonconduction processing of the internal wire so as to increase the delay time. CONSTITUTION:With connection noes N1, N2 connected together, no signal delay is caused between inverters 1 and 4. In cutting off the wire 7 between the connection nodes N1 and N2 externally by a laser beam, since inverters 1, 2, 3 and 4 are connected in series, the delay time due to the increase in the number of inverter stages is increased. When the operation speed of other circuits formed on one and same semiconductor substrate is changed due to fluctuation of the current drive capability of a transistor, the delay time due to the increased number of inverter stages is increased similarly. Then a node is provided between the inverters 2 and 3 and the circuit connecting two inverters 2 in series is increased similarly by one stage.
