Abstract:
An integrated circuit having a wiring structure including a plurality of signal wires and a plurality of ground/power wires which maintain a predetermined minimum wiring pitch, said signal wires and said plurality of ground/power wires each having main parts and other parts at via-hole neighboring regions, whereina ratio of a wiring space between said main parts of every two adjacent ones of said plurality of signal wires to said predetermined minimum wiring pitch is equal to, or higher than, 0.6, and said main parts of said plurality of signal wires and said plurality of ground/power wires have a same wire thickness, and said main parts of said plurality of signal wires have an aspect ratio equal to, or higher than, 2, said aspect ratio being a ratio of said wire thickness to a minimum wire width of said wires.
