  • Patent number: 9202767
    Abstract: Provided are a semiconductor device including a through via plug and a method of manufacturing the same. In the semiconductor device, since a redistributed interconnection pattern is disposed on a protection film of a convex-concave structure having a protrusion and a recessed portion, the semiconductor device may have improved reliability while preventing a leakage current. In the method of manufacturing the semiconductor device, since an end surface of through via structure is exposed by removing a protection film and an insulating film liner using a selective etching process, damage to the through via structure is minimized, thereby preventing copper contamination in a substrate.

  • Patent number: 9196505
    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.
