Abstract:
A conductive grid structure for distributing electrical power with reduced electromigration in an integrated circuit device, said grid structure comprising:a first layer including one or more sets of conducting line segments that are substantially parallel to one another and run in a first direction, each line segment of said one or more sets being of a finite length determined by a diffusion blocking boundary;a layer of diffusion blocking dielectric insulation above the first layer;a second layer including one or more sets of conducting line segments substantially parallel to each other and running in a second direction orthogonal to said first direction, each line segment of said one or more sets being of a finite length determined by a diffusion blocking boundary; and,interlevel contact means disposed substantially vertically through said diffusion blocking dielectric insulation layer for electrically connecting aligned line like segments of respective sets of said one or more sets of line segments of said first and second layers,wherein adjacent finite length segments of each said one or more sets of line segments of each layer are systematically phase shifted and located to enable continuous projection of said grid throughout said integrated circuit device.
