Patent number: 10848897Abstract: An acoustic processing device performs acoustic processing in a space having a first listening position and a second listening position apart from the first listening position. The acoustic processing device includes a first input unit, a first output unit, and a signal processing circuit. The first input unit receives a first sound source signal to be reproduced at the first listening position. The first sound source signal includes a first left-channel signal and a first right-channel signal. The first output unit outputs the first sound source signal to a first speaker group including a first speaker disposed near a place of a head of a listener at the first listening position.

Patent number: 9466559Abstract: In semiconductor integrated circuit devices for vehicle use, an aluminum pad on a semiconductor chip and an external device are coupled to each other by wire bonding using a gold wire for the convenience of mounting. Such a semiconductor integrated circuit device, however, causes a connection failure due to the interaction between aluminum and gold in use for a long time at a relatively high temperature (about 150 degrees C.). A semiconductor integrated circuit device can include a semiconductor chip as a part of the device, an electrolytic gold plated surface film (gold-based metal plated film) provided over an aluminum-based bonding pad on a semiconductor chip via a barrier metal film, and a gold bonding wire (gold-based bonding wire) for interconnection between the plated surface film and an external lead provided over a wiring board (wiring substrate).Type: GrantFiled: September 12, 2011Date of Patent: October 11, 2016Assignee: RENESAS ELECTRONICS CORPORATIONInventors: Hiromi Shigihara, Hiroshi Tsukamoto, Akira Yajima

Patent number: 8592984Abstract: To suppress peeling of an Au pad for external coupling provided in a rewiring containing Cu as a main component. On the surface of a rewiring including a two-layer film in which a first Ni film is laminated on the top of a Cu film, a pad to which a wire is coupled is formed. The pad includes a two-layer film in which an Au film is laminated on the top of a second Ni film and formed integrally so as to cover the top surface and the side surface of the rewiring. Due to this, the area of contact between the rewiring and the pad increases, and therefore, the pad becomes difficult to be peeled off from the rewiring.Type: GrantFiled: June 14, 2011Date of Patent: November 26, 2013Assignee: Renesas Electronics CorporationInventors: Hiromi Shigihara, Akira Yajima, Hisao Shigihara, Hiroshi Tsukamoto
