Redistribution substrate having redistribution pattern including via seed patterns covering bottom surface and sidewall surface of wiring conductive patterns and semiconductor package including the same
Abstract:
Disclosed are redistribution substrates and semiconductor packages including the same. For example, a redistribution substrate including a dielectric pattern, and a first redistribution pattern in the dielectric pattern is provided. The first redistribution pattern may include: a first via part having a first via seed pattern and a first via conductive pattern on the first via seed pattern, and a first wiring part having a first wiring seed pattern and a first wiring conductive pattern, the first wiring part being disposed on the first via part and having a horizontal width that is different from a horizontal width of the first via part. Additionally, the first wiring seed pattern may cover a bottom surface and a sidewall surface of the first wiring conductive pattern, and the first via conductive pattern is directly connected to the first wiring conductive pattern.
