    Abstract: A semiconductor package includes a redistribution substrate that includes a first redistribution pattern and a second redistribution pattern that are at different levels from each other, and a semiconductor chip on the redistribution substrate and including a plurality of chip pads electrically connected to the first and second redistribution patterns. The first redistribution pattern includes a first metal pattern on a first dielectric layer, and a first barrier pattern between the first dielectric layer and a bottom surface of the first metal pattern. The second redistribution pattern includes a second metal pattern in a second dielectric layer, and a second barrier pattern between the second dielectric layer and a bottom surface of the second metal pattern and between the second dielectric layer and a sidewall of the second metal pattern.

    Abstract: Disclosed is a semiconductor device including a conductive pattern on a substrate, a passivation layer on the substrate and including an opening that partially exposes the conductive pattern, and a pad structure in the opening of the passivation layer and connected to the conductive pattern. The pad structure includes a first metal layer that fills the opening of the passivation layer and has a width greater than that of the opening, and a second metal layer on the first metal layer. The first metal layer has a first thickness at an outer wall of the first metal layer, a second thickness on a top surface of the passivation layer, and a third thickness on a top surface of the conductive pattern. The second thickness is greater than the first thickness, and the third thickness is greater than the second thickness.
