Patent JP-H11234104-A (JP)
Title: Semiconductor module and inverter device
Inventor: SATO SHINJI
IPC: H02M1/08
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To suppress surge voltage at the time of interrupting a large current and to execute fast switching at the time of a normal current by connecting a gate resistor, which varies resistance according to the output signal of a sense terminal outputting a signal depending on the size of a collector current, to a gate terminal. SOLUTION: As for an FET 8a being a variable resistor, since a gate terminal and a source terminal are connected by a resistor 9, a gate-source voltage becomes zero to obtain a conduction at a normal time. When a current flowing through the IGBT 4 is increased in the state of applying positive voltage from a gate driving circuit 2, a large current flowsthrough the sense terminal S depending on to. A transistor 7 becomes conductive with this and the FET 8a is actively turned off to raise the resistance between the drain and source of the FET 8a. Thereby, when a large current flows, the gate resistance is equivalently increased to make it possible to turn off the large current at a low speed.

Title: Bump forming method
Inventor: NISHIMORI TAKASHI
IPC: H01L21/60
Filed: 1992-01-20
Abstract: PURPOSE:To form bumps having approximately uniform heights and compositions on electrodes by a method wherein barrier metals around alignment chip are removed by etching in a first photolithography step and bump forming patterns are formed in a second photolithography step. CONSTITUTION:Bumps are formed on a wafer 6' on which semiconductor circuit chips 1 are formed and, at the same time, alignment chips 3' respectively having two photolithography alignment marks 2' used for forming bumps are formed and which is so covered with a circuit protective film 4 overall as to expose only the square electrode parts 5 of the semiconductor circuit chips 1. As no current flows through barrier metals in the alignment chip 3' during the wet electroplating, the bumps are not made to grow except om the electrode parts 5 of the semiconductor circuit chips 1, so that all the bumps in the wafer 6' are plated under approximately equal conditions. In such a way, the bumps having approximately uniform heights and compositions can be formed on the electrodes over the whole wafer.

Abstract: PROBLEM TO BE SOLVED: To make the Q-value of a coil through which a core is inserted large and to reduce costs by forming a thin film core on a circuit board, cutting it to small parts and providing thin film winding inductors obtained by applying conductor winding. SOLUTION: Chip capacitors 11 of a 1005 system or a 0603 system are mounted in a glass ceramics multilayer board 10. The mounting of the capacitors 11 on the board 10 is performed by applying solder paste, subsequently raising temperature with a reflow furnace, etc., and connecting the capacitors 11.

Title: Light quantity adjusting device
Inventor: SATO OSAMU
IPC: G03B9/02
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to set a desired aperture opening within a driving range with simple constitution by providing a stator yoke with a notch and setting the magnetical stable point of the detent torque acting between a rotor magnet and the stator yoke within the driving range. SOLUTION: The rotor magnet 1 is rotated in a small aperture direction and stops at a regulated position when the detent torque arises between the magnetic poles of the notched apart 14 of the stator yoke 2 and the rotor magnet 1 and a current of one direction flows in the driving coil 3. The aperture opening is then determined by moving light quantity varying members 9, 10. When the current of another direction flows in the coil 3, the rotor magnet 1 rotates in the open aperture direction and stops at the magnetical stable point of the detent torque. The aperture opening corresponding to the middle is then determined by moving the light quantity varying members 9, 10. A coil 3 (and a braking coil 4) is disposed within the range where the coil does not face the notched apart 14 of the stator yoke 2 and, therefore, the deterioration of the torque by the increased magnetic reluctance and the decreased magnetic flux density is lessened.
