Patent number: 8116100Abstract: Traffic between logic LSIs and memory is increasing year by year and there is demand for increase of capacity of communication between them and reduction of power consumption in the communication. Communication distances between LSIs can be reduced by stacking the LSIs. However, in a simple stack of logic LSIs and memory LSIs, it is difficult to ensure heat dissipation to cope with increasing heat densities and ensure transmission characteristics for fast communication with the outside of the stacked package. Also required is a connection topology that improves the performance of communication among the stacked LSIs while ensuring the versatility of the LSIs. An external-communication LSI, a memory LSI, and a logic LSI are stacked in this order in a semiconductor package and are interconnected by through silicon vias.Type: GrantFiled: May 14, 2009Date of Patent: February 14, 2012Assignee: Hitachi, Ltd.Inventors: Makoto Saen, Kenichi Osada

Patent number: 8110457Abstract: To provide a semiconductor device with improved reliability which includes a metal silicide layer formed by a salicide process. After forming gate electrodes, an n+-type semiconductor region, and a p+-type semiconductor region for a source or drain, a Ni1?xPtx alloy film is formed over a semiconductor substrate. The alloy film reacts with the gate electrodes, the n+-type semiconductor region, and the p+-type semiconductor region by a first heat treatment to form a metal silicide layer in a (Ni1?yPty)2Si phase. At this time, the first heat treatment is performed at a heat treatment temperature where a diffusion coefficient of Ni is larger than that of Pt. Further, the first heat treatment is performed such that a reacted part of the alloy film remains at the metal silicide layer. This results in y>x. Then, after removing the unreacted part of the alloy film, the metal silicide layer is further subjected to a second heat treatment to form a metal silicide layer in a Ni1?yPtySi phase.Type: GrantFiled: September 20, 2009Date of Patent: February 7, 2012Assignee: Renesas Electronics CorporationInventor: Takuya Futase

Patent number: 8108660Abstract: Each of processors has a barrier write register and a barrier read register. Each barrier write register is wired to each barrier read register by a dedicated wiring block. For example, a 1-bit barrier write register of a processor is connected, via the wiring block, to a first bit of each 8-bit barrier read register contained in the processors, and a 1-bit barrier write register of another processor is connected, via a wiring block, to a second bit of each 8-bit barrier read register contained in the processors. For example, a processor writes information to its own barrier write register, thereby notifying synchronization stand-by to the other processors and reads its own barrier read register, thereby recognizing whether the other processors are in synchronization stand-by or not. Therefore, a special dedicated instruction is not required along barrier synchronization processing, and the processing can be made at a high speed.Type: GrantFiled: January 22, 2009Date of Patent: January 31, 2012Assignees: Renesas Electronics Corporation, Waseda UniversityInventors: Hironori Kasahara, Keiji Kimura, Masayuki Ito, Tatsuya Kamei, Toshihiro Hattori
