  • Publication number: 20120013019
    Abstract: A signal line is formed in the a-th layer (a?2) of a multi-layered interconnect layer and a redistribution layer. A plain line is formed in the b-th layer (b<a) of the multi-layered interconnect layer and the redistribution layer and overlaps with the signal line when seen in a plan view. Two coplanar lines that are formed in the c-th layer (b?c?a) of the multi-layered interconnect layer and the redistribution layer, extend in parallel to the signal line when seen in a plan view, and interpose the signal line therebetween. A distance h from the signal line to the plain line is smaller than a distance w from the signal line to the coplanar lines. A power supply line, a ground line, and another signal line are not located within the range of the height equal to the distance w from the signal line above the signal line.

  • Patent number: 7310040
    Abstract: The present invention provides an improved manufacturing stability of a semiconductor device provided with a spiral inductor. The semiconductor device 100 includes a silicon substrate 101, an element isolating oxide film embedded within the silicon substrate 101, a first insulating interlayer provided on the silicon substrate 101, a spiral inductor 120 provided on the first insulating interlayer, and a shielding layer, which is provided between the spiral inductor 120 and the silicon substrate 101, and elongates toward a direction along the surface of the substrate to provide a shield between the spiral inductor 120 and the silicon substrate 101. Then, a plurality of substrate remaining regions 131 formed by the silicon substrate 101 partially remaining in the element isolating oxide film in a form of islands from the upper viewpoint are selectively provided right under the polysilicon 105 in the region for forming the spiral inductor 120.

  • Publication number: 20050258508
    Abstract: A semiconductor device includes a semiconductor substrate, and a multi-layered wiring arrangement formed on the semiconductor substrate and having insulating interlayers stacked in order thereon. A first inductor is formed on one of the insulating layers of the multi-layered wiring arrangement. A second inductor has a smaller size than the first inductor, and is formed on the same insulating interlayer as the first inductor, so that the second inductor is arranged inside of the first inductor.
