Title: Tape carrier with bump
Inventor: SEKI HIROSHI
IPC: H01L21/60
Filed: 1987-03-17
Abstract: PURPOSE:To omit a bump at a part to be bonded on an IC chip and the like and to add and form the bump on a lead readily, by pressing an irregular pattern on the tip part of the lead, thereby providing a protruding electrode. CONSTITUTION:A pressed bump 1a, which is formed by press machining, is bonded to a material to be bonded such as an IC by thermocompression bonding and the like. The material to be bonded and the lead of a tape carrier are connected. Since a pressed lead part 2a, which is a bump holding part, is compressed with press machining, its mechanical strength is high, and bump holding strength is also high. Therefore drooping of the bump part 1a can be prevented, and the positioning accuracy in bonding can be improved. Since the bump part 1a of the lead is machined with the press, the area and the shape of the bonding part can be limited readily, the extra protruding part of the bump part 1a can be eliminated and the lead interval and the lead pitch can be made small.

Title: Electron gun, electron beam equipment and electron beam irradiation method
Inventor: DAIKYO YOSHIHISA
IPC: H01L21/027
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To uniform the current density distribution of a radiation electron beam, improve the life, and facilitate adjustment. SOLUTION: A control electrode 49 which faces a cathode 40 whose tip is almost a turncated cone and has an aperture formed in the optical axis part, a leading-out electrode 48, a lens electrode 42 and an anode 41 are arranged in this order. As to the control electrode 49, the optical axis direction position of the aperture A2 is nearly equal to the tip surface position of the cathode. An aperture of the leading-out electrode 48 is smaller than the cathode tip surface. A potential V3 lower than an anode potential V0 and higher than a cathode potential V1 is applied to the leading-out electrode, thereby leading out an electron beam from the cathode 40. The electron beam which has passed through an aperture A3 is accelerated by the potential difference between the anode and the cathode.  Potentials V2 and V4 lower than the cathode potential V1 are applied to the control electrode 49 and the lens electrode 42, respectively, thereby controlling independently a cathode current and a crossover position. The control potential V2 is so controlled that the difference between a current 11 flowing through the cathode and a current 12 flowing through the leading-out electrode becomes constant.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To preclude permanent deformation by forming a lever interlock switch from an elastic material and prevent a microswitch actuator from breakage even in case the interlock switch is over-pushed. SOLUTION: A lever interlock switch is made of an elastic material, and the forefront of a microswitch pressing part 4b-2 is arranged to collide with the front side-face 1-1 of a bracket interlock switch 1. Thus the deformation part of the lever interlock switch can be prevented from permanent deformation, and it is possible to push in the actuator 2-1 of microswitch 2 certainly. Because the forefront of the microswitch pressing part 4b-2 of the lever interlock switch runs against the front side-face 1-1 of the bracket interlock switch 1, the actuator 2-1 can be prevented from breakage even in case the lever interlock switch 4b is over-pushed.
