Semiconductor device having multi-level wiring structure

A semiconductor device may include, but is not limited to, a first signal line, a second signal line, and a first shield line. The first signal line is supplied with a first signal. The first signal is smaller in amplitude than a potential difference between a power potential and a reference potential. The second signal line is disposed in a first side of the first signal line. The second signal line is supplied with a second signal. The second signal is smaller in amplitude than the potential difference. The first shield line is disposed in a second side of the first signal line. The second side is opposite to the first side. The first shield line reduces a coupling noise that is applied to the first shield line from the second side.

Semiconductor device with signal lines and shield lines

A semiconductor integrated circuit includes power supply pads of two or more kinds, switches each of which is connected between adjacent two of the power supply pads to allow short-circuiting them, and at least one control line connected to control terminals of the switches according to the kinds of the power supply pads connected to the switches.

Semiconductor integrated circuit

A plurality of unit areas having one to a plurality of MOSFETs for implementing specific logic circuits are placed in a first direction. A first interconnection extending in the first direction is formed over each unit area. A second interconnection extending in the first direction is formed along the plurality of unit areas and outside the unit areas. Wiring dedicated areas provided with a third interconnection extending in a second direction intersecting the first direction are respectively provided between the adjacent unit areas. A logic circuit formed in each unit area has both a first connection form connected to the first interconnection and a second connection form connected to the third interconnection, via the second interconnection, according to combinations with the wiring dedicated areas adjacent thereto, as needed.
