Connection wiring

A connection wiring comprising:

• a plurality of pads disposed in a multi-stage staggered arrangement with four or more stages;
• and
• a plurality of lines respectively extending from the pads, wherein,
• the pads include first pad layers formed on a substrate and second pad layers stacked on top of the first pad layers and smaller than the first pad layers,
• the lines include first lines formed in the same tier as the first pad layers and extending from the first pad layers and second lines formed in the same tier as the second pad layers and extending from the second pad layers,
• in an area between the pads arranged in the same stage, at least one of the first lines and at least two of the second lines are disposed parallel to one another such that two of the second lines are situated on opposite sides of one of the first lines so as to have the first line positioned therebetween, and
• in an intersecting area between pad rows of adjacent stages, a first type of either the first or second lines crosses a second type of line adjacent to a first type above or below a second type so as to be positioned between a different pair of a second type of lines and extend toward an area between the pads in a pad row in a subsequent stage.
