Semiconductor package device

Disclosed is a semiconductor package device comprising a semiconductor chip including first and second chip pads on an active surface of the semiconductor chip, and a redistribution substrate on the first and second chip pads. The redistribution substrate includes first and second redistribution patterns sequentially stacked on the active surface. The first redistribution pattern includes a first via part and a first via pad part vertically overlapping the first via part. The second redistribution pattern includes a second via part and a second via pad part vertically overlapping the second via part. The first via part contacts the first chip pad. The second via part contacts the second chip pad. A length of the second via part is greater than that of the first via part.
