Definition of interconnect density

1. the patterns of electrical conductors that are provided both on and off semiconductor die to connect circuit elements and to interface with other system elements; the number of such conductors that are provided in a 1- or 2-dimensional space per dimension unit. Alternatively, interconnect density may be defined by the conductor pitch that is the sum of the conductor width and the space to the next conductor.
