Patent number: 8618579Abstract: To provide a circuit layout design method that can prevent degradation of the circuit reliability even in highly miniaturized circuit cells. In order to prevent noise from a power supply potential or a reference potential with a large potential difference from affecting a gate electrode and causing a malfunction, a first plug connected to the gate electrode and a second plug to which the power supply potential or the reference potential is supplied are required to be spaced from each other by a distance sufficient for the noise from the power supply potential or the reference potential not to affect the first plug. To this end, among the second plugs placed at equal intervals under the wiring, only the second plug placed at a layout position that is not sufficiently spaced from the first plug is deleted at the time of planar layout design.Type: GrantFiled: November 16, 2012Date of Patent: December 31, 2013Assignee: Renesas Electronics CorporationInventors: Hiroharu Shimizu, Masakazu Nishibori, Toshihiko Ochiai

Patent number: 8618586Abstract: An object is to provide a memory device which does not need a complex manufacturing process and whose power consumption can be suppressed, and a semiconductor device including the memory device. A solution is to provide a capacitor which holds data and a switching element which controls storing and releasing charge in the capacitor in a memory element.

Patent number: 8618587Abstract: An electronic device employing a graphene layer as a charge carrier layer. The graphene layer is sandwiched between layers that are constructed of a material having a highly ordered crystalline structure and a high dielectric constant. The highly ordered crystalline structure of the layers surrounding the graphene layer has low density of charged defects that can lead to scattering of charge carriers in the graphene layer. The high dielectric constant of the layers surrounding the graphene layer also prevents charge carrier scattering by minimizing interaction between the charge carriers and the changed defects in the surrounding layers. An interracial layer constructed of a thin, non-polar, dielectric material can also be provided between the graphene layer and each of the highly ordered crystalline high dielectric constant layers to minimize charge carrier scattering in the graphene layer through remote interfacial phonons.Type: GrantFiled: June 25, 2012Date of Patent: December 31, 2013Assignee: HGST Netherlands B.V.Inventors: Ernesto E.
