Patent number: 8240539Abstract: The joining apparatus includes a suction nozzle for holding an electronic component, a board stage for holding a circuit board in opposition to the electronic component, and an excimer ultraviolet lamp placed at an irradiation position between the positioned electronic component and circuit board. In such a joining apparatus, ultraviolet irradiation to Au bumps of the electronic component and ultraviolet irradiation to board electrodes of the circuit board are performed concurrently by the excimer ultraviolet lamp to execute a cleaning process of the two metallic portions. Thereafter, ultrasonic vibrations are imparted to the two metallic portions while those metallic portions are kept in contact with each other, by which metal joining between the two metallic portions is fulfilled.Type: GrantFiled: May 25, 2005Date of Patent: August 14, 2012Assignee: Panasonic CorporationInventors: Kazushi Higashi, Tatsuo Sasaoka, Shinji Ishitani

Patent number: 8129739Abstract: In a semiconductor light emitting device having a matrix of a plurality of bumps composed of one n-bump formed on an n-electrode layer and of a large number of p-bumps formed on p-electrode layers, the occurrence of a faulty junction after mounting can be suppressed by placement of the n-bump at center of the bump array, because the position at the center is most resistant to occurrence of stress after the mounting. Employment of such a configuration of bump array increases reliability of mounting thereof while improving uniformity of light emission intensity in the semiconductor light emitting device having an increased size.Type: GrantFiled: July 12, 2006Date of Patent: March 6, 2012Assignee: Panasonic CorporationInventors: Kazushi Higashi, Shinji Ishitani

Patent number: 7692292Abstract: A first container member (9, 109, 212) mounting an electronic device (71, 171, 261) thereon and a second container member (2, 102, 202) are bonded with an adhesive (3, 103) or a metal layer (103, 251). Thus an inner space (90, 190, 211) is formed and the electronic device can be closed in the inner space at a low temperature. In the case the adhesive is used, an exposed surface of the adhesive is coated with a metal film (4) to improve the closeness of the inner space. Further, an electronic device (261, 272) may be mounted on the second container member so as to increase the electronic device arrangement density in a packaged electronic device.Type: GrantFiled: December 2, 2004Date of Patent: April 6, 2010Assignee: Panasonic CorporationInventors: Kazushi Higashi, Shinji Ishitani

Patent number: 7554126Abstract: An LED chip of the present invention has a structure in which an n-type semiconductor layer and a p-type semiconductor layer are successively formed on the lower face of an element substrate, with the p-type semiconductor layer being formed on an area except for an area for an n-electrode. A first n-electrode is formed on the area for the n-electrode and a first p-electrode is formed on the p-type semiconductor layer. A first insulating layer having openings and is formed on the first n-electrode and the first p-electrode, and a second n-electrode and a second p-electrode having virtually the same size are formed on the first insulating layer. With this arrangement, the electrode on the n-type semiconductor layer can be made larger, thereby a mounting process of LED chips onto a circuit board can be executed by using solder at low costs.Type: GrantFiled: September 22, 2005Date of Patent: June 30, 2009Assignee: Panasonic CorporationInventors: Kazushi Higashi, Shinji Ishitani

Patent number: 7550715Abstract: A positive electrode drive unit enables a positive electrode to be repeatedly rotated about the center of the positive electrode to vary a distance between the positive electrode and an atom emission unit. A control unit receives input data which is set to obtain a desired atom density distribution by displacement of the positive electrode, and the control unit outputs a drive control signal for displacing the positive electrode to the positive electrode drive unit. The positive electrode drive unit is stopped during running by the control unit, or a drive speed of the positive electrode drive unit is changed by the control unit. Therefore, a residence time of each attitude is changed in the positive electrode to vary the atom density per unit time.Type: GrantFiled: April 26, 2007Date of Patent: June 23, 2009Assignee: Panasonic CorporationInventors: Takashi Omura, Shinji Ishitani, Naoki Suzuki
