    Abstract: Disclosed are interconnection structures and semiconductor packages. The interconnection structure includes a first dielectric layer and a first hardmask pattern that are sequentially stacked, and a first interconnection pattern that penetrates the first hardmask pattern and the first dielectric layer. The first hardmask pattern includes a dielectric material having an etch selectivity with respect to the first dielectric layer. The first interconnection pattern includes a via part, a first pad part, and a line part that are integrally connected to each other. The first pad part vertically overlaps the via part. The line part extends from the first pad part. A level of a bottom surface of the first pad part is lower than a level of a bottom surface of the line part.
