Publication number: 20130055188Abstract: A semiconductor device for layout has first and second power supply domains and has wiring connected to and from cells belonging to a second power supply domain. A wiring inhibited/allowed area setting unit sets an exclusive wiring inhibited area and a pass-through wiring allowed area within the first power supply domain based on a repeater wire maximum length being a maximum wire length which a repeater buffer can drive. A wiring setting unit modifies wiring based on the exclusive wiring inhibited area and the pass-through wiring allowed area. A repeater insertion unit sets a repeater buffer to be inserted on a wire according to the repeater wire maximum length. The exclusive wiring inhibited area allows wiring connecting cells within the first power supply domain and inhibits pass-through wiring. The pass-through wiring allowed area, being the first power supply domain excluding the exclusive wiring inhibited area, allows pass-through wiring.Type: ApplicationFiled: August 23, 2012Publication date: February 28, 2013Applicant: RENESAS ELECTRONICS CORPORATIONInventor: Hideaki FUTAKATA

Publication number: 20130037852Abstract: Super-junction MOSFETs by trench fill system requires void-free filling epitaxial growth. This may require alignment of plane orientations of trenches in a given direction. Particularly, when column layout at chip corner part is bilaterally asymmetrical with a diagonal line between chip corners, equipotential lines in a blocking state are curved at corner parts due to column asymmetry at chip corner. This tends to cause points where equipotential lines become dense, which may cause breakdown voltage reduction. In the present invention, in power type semiconductor active elements such as power MOSFETs, a ring-shaped field plate is disposed in chip peripheral regions around an active cell region, etc., assuming a nearly rectangular shape. The field plate has an ohmic-contact part in at least a part of the portion along the side of the rectangle. However, in the portion corresponding to the corner part of the rectangle, an ohmic-contact part is not disposed.Type: ApplicationFiled: July 13, 2012Publication date: February 14, 2013Applicant: RENESAS ELECTRONICS CORPORATIONInventor: Tomohiro TAMAKI
