Patent number: 8408356Abstract: A box-shaped enclosure of a storage box includes a deadening wall or walls defining a storage space between first and second planes. The storage space is open at the first and second planes. A deadening wall member extends along the first plane. An auxiliary box-shaped enclosure is connected to the box-shaped enclosure so as to close the first plane of the box-shaped enclosure. The auxiliary box-shaped enclosure defines an auxiliary space isolated from the storage space with a deadening wall member. The storage space is connected to the fresh air through the ventilation opening and the auxiliary space. The deadening wall or walls of the box-shaped enclosure and the deadening wall member serve to prevent the leakage of the operating sound.Type: GrantFiled: April 16, 2008Date of Patent: April 2, 2013Assignee: Fujitsu LimitedInventors: Atsushi Yamaguchi, Junichi Ishimine, Masahiro Suzuki, Tadashi Katsui, Shin-ichirou Kouno, Akira Takahashi, Akihiro Watanabe, Tomohiro Okazaki

Publication number: 20100269333Abstract: The objective of this invention is to provide an ultrasonic flip-chip mounting method with little variance in the formed electrode joints between a semiconductor chip and a substrate. The ultrasonic method for mounting a flip chip of the present invention may include a step for forming several bump electrodes (106) on the main surface of one side of a semiconductor chip (100) and a step for respectively bringing several projecting electrodes (106) into contact with the corresponding conductor patterns (132) on a substrate and for applying ultrasonic vibration to the semiconductor chip, where the ultrasonic vibration direction is oriented in a direction oblique to the electrode patterns (132). In this way, an effective width for joining formation W1 is greater than the width of the conductor patterns W of the electrode patterns (132).Type: ApplicationFiled: April 23, 2010Publication date: October 28, 2010Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Mutsumi MASUMOTO, Noboru NAKANISHI, Tomohiro OKAZAKI

Publication number: 20040229425Abstract: An object of the invention is to improve the position, shape, and size of a bump in order to realize highly reliable flip-chip mounting. In the case of the semiconductor device of this embodiment, a stacked bump 14 is provided on electrode pad 12 created on the main surface of semiconductor chip 10. That is, said bump 14 comprises columnar pedestal part 14a and columnar tail part 14b having a smaller diameter than that of pedestal part 14a. Peak plane of tail part 14b (peak plane of the bump) and the top surface of pedestal part 14a are both flat. Said bump 14 is created through gold plating, for example, using a resist (photolithography) technology and a plating technology.Type: ApplicationFiled: June 7, 2004Publication date: November 18, 2004Inventors: Katsumi Yamaguchi, Tomohiro Okazaki, Takako Yamaguchi
