Abstract

A method of fabricating semiconductor packages includes providing an interposer layer having a first surface and a second surface opposite to the first surface, in which the interposer layer includes through interposer vias embedded inside, and the through interposer vias extended from the first surface toward the second surface, in which through interposer vias are patterned to form repetitive polygonal-packing units, and part of the through interposer vias can be grouped within at least two distinct said polygonal-packing units; subsequently, forming at least one redistribution layer on the first surface to form terminals on a surface of the redistribution layer away from the interposer layer, in which the terminals are selectively connected to the through interposer vias respectively; and then disposing at least one semiconductor chip on the redistribution layer, wherein the semiconductor chip includes active surfaces electrically connected to the terminals respectively.
