Abstract: In a semiconductor device, an organic insulation pattern is disposed between first and second rerouting patterns. The organic insulation pattern may absorb the physical stress that occurs when the first and second rerouting patterns expand under heat. Since the organic insulation pattern is disposed between the first and second rerouting patterns, insulating properties can be increased relative to a semiconductor device in which a semiconductor pattern is disposed between rerouting patterns. Also, since a seed layer pattern is disposed between the first and second rerouting patterns and the organic insulation pattern and between the substrate and the organic insulation pattern, the adhesive strength of the first and second rerouting patterns is enhanced. This also reduces any issues with delamination. Also, the seed layer pattern prevents the metal that forms the rerouting pattern from being diffused to the organic insulation pattern.
