Abstract:
1. A semiconductor integrated circuit, comprising: a first wiring formed on a first wiring layer and prolonged in a first direction; a second wiring formed on a second wiring layer and comprising a first portion and a second portion, the first portion being prolonged in a second direction intersecting with said first direction; a third wiring formed on the first wiring layer and prolonged in the first direction; a fourth wiring formed on the second wiring layer and prolonged in the second direction; a first overlap area in which said first wiring and said second wiring overlap each other; a second overlap area in which said third wiring and said fourth wiring overlap each other; a multi-cut via formed to connect the first wiring to the second wiring in said first overlap area, the multi-cut via including a first via and a second via formed in the first direction; and a single-cut via formed to connect the third wiring to the fourth wiring in said second overlap area, wherein said second portion of said second wiring is formed in said first overlap area, and is prolonged to said first direction, wherein a width of said second portion of said second wiring corresponding to said first direction is longer than a width of said first portion of said second wiring corresponding to said first direction, wherein one end of said first overlap area intersects with said first direction, said first via, said second via, and another end of said first overlap area intersecting with said first direction are formed, wherein one of a distance between said one end and a center of said first via or a distance between said another end and a center of said second via is shorter than a distance between a center of said single-cut via and an end of said second overlap area intersecting with said first direction, and wherein a distance between the center of said first via and the center of said second via is longer than said width of said first portion of second wiring.
