Abstract: PURPOSE:To simplify a manufacturing process and hence prevent wiring aluminum from being damaged by forming a connection film among bonding pads so as to bring all bonding pads into the same potential and thereafter forming a surface protecting oxide film, and plating bumps and thereafter fusing the connection film. CONSTITUTION:To bring all bonding pads 103 of a chip into the same potential, the bonding pads 103 are patterned such that each of them is connected to adjacent bonding pad through a connection film 103.

Thereafter, the connection film 100 for connecting among the bonding pads 103 is fused by a laser beam. A manufacturing process is simplified in a bump formation process and hence a wiring aluminum film can be prevented from being damaged.

Title: Specimen surface analyzing device
Inventor: SOEJIMA HIROYOSHI
IPC: H01J37/252
Filed: 1989-12-12
Abstract: PURPOSE:To make analysis with high resolution both in the crosswise and depth directions of a specimen surface and with excellent quantitative determinating performance by converging an ion beam on the specimen surface with a specified acceleration voltage, furnishing a mass spectrometric means and X-ray spectrometric means confronting the ion beam irradiation point on the specimen surface, and also providing a sensing means to sense the secondary electrons emitted by the specimen. CONSTITUTION:An ion beam is converged on a specimen surface with an acceleration voltage under 100kV, and an X-ray spectrometric means 4 and mass spectrometric means 5 are arranged so as to confront the ion beam irradiation point on the specimen surface, and bedside them a secondary electron sensing means 6 is installed. In the case of ion irradiation, the ion diffusion region W is shallower than in the case of electron irradiation, which is the X-ray generating region, and also is the secondary electron generating range. Accordingly there is little information about the inside of the specimen, so that information of the pure surface configuration of specimen will be obtained. For X-rays, on the other hand, the X-ray generating region does not substantially widen greater in the direction extending along the specimen surface than the dia. of ion beam. This enables obtainment of high locational resolution both in the parallel direction to the specimen surface and in the depth direction, and provides possibility of analysis with excellent quantitative determinating performance which has not been achieved according to SIMS.

Title: Controlling method of shift mechanism of automatic mechanical type transmission
Inventor: DANIERU POORU JIYANEKII
IPC: F16H61/32
Filed: 1993-11-29
Abstract: PURPOSE: To shift a transmission to a neutral position by quickly disengaging the engagement of a transmission, without accompanying excessive electric power consumption, the abrasion of a transmission, or the over heat of a motor. CONSTITUTION: In a controlling method used in an automatic mechanical transmission including an electric actuating shift mechanism 12 provided with a motor 70, the mechanism 12 is actuated by a low effective voltage signal to apply a pre-loading force to a shift rail, and the motor 70 cuts off a transmission gear by transmission torque at the time of gear engaging, without the rotation and movement of the shift rail. Moreover the rotation of the motor is quickly detected by the reduction of the torque to increase pulse width, thereby maintaining a target current following the rotation of the motor 70, and the transmission gear is cut off during the interruption of the torque to shift the gear to a neutral position. Consequently power consumption can be suppressed to the minimun, and also the overheat of the motor can be avoided.

Filed: 1991-12-09
Abstract: PURPOSE:To prevent outflow of fine particles when contaminant of a stocking standard sample for inspecting a surface of a wafer is cleaned by securing the particles scattered on the wafer by covering it with a stationary film. CONSTITUTION:Fine particles 2 granulated from latex of polyethylene are scattered on an Si wafer 1 polished in a mirror surface. It is covered with a stationary film 3 by sputtering.
