An interconnection structure and a manufacturing method thereof are provided. The method includes the following steps. First, a substrate having a first surface and a second surface opposite to each other is provided. Then, a conductive through via extended from the first surface to the second surface is formed in the substrate. Then, a portion of the substrate is removed from the first surface to expose a portion of the conductive through via. Then, a dielectric layer is formed on the substrate, and the dielectric layer covers the exposed conductive through via. Then, an opening is formed in the dielectric layer, wherein the opening exposes a portion of the conductive through via, and the top surface of the conductive through via protrudes from the bottom surface of the opening. Then, a conductive layer is formed in the opening.

A method for manufacturing an interposer includes the following steps. Conductive beads is filled in a blind via of a substrate and a solder layer of each conductive bead is melted so as to form a solder post in the blind via. A metal ball of each conductive bead is inlaid in the corresponding solder post such that the solder post and the metal balls inlaid therein construct a conductive though via. Two surfaces of the substrate are planarized such that two ends of the conductive through via are exposed to the two surfaces of the substrate respectively and are flush with the two surfaces of the substrate respectively. A redistribution layer is manufactured at each surface of the substrate such that the two ends of each conductive through via connect the redistribution layers respectively.
