Patent number: 8629529Abstract: A semiconductor device is produced by fabricating a capacitor element including a lower electrode, a capacitor insulating film, and an upper electrode, and a thin-film resistor element, in the same step. As the lower electrode of the capacitor element is lined with a lower layer wiring layer (Cu wiring), the lower electrode has extremely low resistance substantially. As such, even if the film thickness of the lower electrode becomes thinner, parasitic resistance does not increased. The resistor element is formed to have the same film thickness as that of the lower electrode of the capacitor element. Since the film thickness of the lower electrode is thin, it works as a resistor having high resistance. In the top layer of the passive element, a passive element cap insulating film is provided, which works as an etching stop layer when etching a contact of the upper electrode of the capacitor element.Type: GrantFiled: December 25, 2007Date of Patent: January 14, 2014Assignee: NEC CorporationInventors: Naoya Inoue, Ippei Kume, Jun Kawahara, Yoshihiro Hayashi

Patent number: 8386692Abstract: According to an aspect of the embodiment, an input/output device transmits a message to a first node controller of a parent node which is set in advance via a cross bar. At this point, the cross bar generates information based on node information of the input/output device, and adds the generated information to the message. The first node controller transmits, via the cross bar, the message to a second node controller of a parent node corresponding to an input/output device that is to receive the message. The second node controller transmits, via the cross bar, the message to an input/output device that is to receive the message. At this point, the cross bar transmits the message restored by deleting the generated information from the message to the input/output device which is set as a destination.Type: GrantFiled: February 1, 2011Date of Patent: February 26, 2013Assignee: Fujitsu LimitedInventor: Jun Kawahara
