Abstract:
A package substrate includes a substrate including a circuit region, a dummy region surrounding the circuit region, and a lower circuit pattern at the dummy region, the circuit region including unit regions arranged in a matrix shape, and solders on the lower circuit pattern, at least one of the solders electrically connected to the lower circuit pattern.
Abstract:
Provided are a package substrate and a method of fabricating a semiconductor package. The package substrate includes: a base substrate having a plurality of packaging unit regions arranged along rows and columns on one surface thereof; and a sink portion penetrating at least a portion of the base substrate from the one surface, in which the packaging unit regions may be disposed adjacent to a first side of the one surface and the sink portion may be disposed adjacent to a second side of the one surface.
