摘要:
A semiconductor integrated circuit device (10) is composed of an LSI function unit (11) and a shield wiring layer (22) formed on the unit. The LSI function unit (11) includes a semiconductor substrate (12) and a first insulating film (13), and the semiconductor substrate (12) is formed with a circuit element including, for example, a MOS transistor (14). The shield wiring layer (22) is composed of a lower shield line (23), a third insulating film (24), an upper shield line (25), and a fourth insulating film (26) sequentially stacked above a second insulating film (17). The directions in which the lower and upper shield lines (23) and (25) are arranged intersect each other.
摘要:
A basic cell of the present invention comprises a plurality of wires which constitute a wiring route of 90°, one ends of the wires being on one of opposite sides, and the other ends of the wires being on the other one of the opposite sides, wherein: each of the one ends of the wires is point-symmetric to any of the other ends of the wires with respect to the center of the area of the basic cell; and routes of the plurality of wires do not cross one another.
