摘要:
A stacked semiconductor package having through electrodes that exhibit a reduced leakage current and a method of making the same are presented. The stacked semiconductor package includes a semiconductor chip, through-holes, and a current leakage prevention layer. The semiconductor chip has opposing first and second surfaces. The through-holes pass entirely through the semiconductor chip and are exposed at the first and second surfaces. A polarized part is formed on at least one of the first and second surfaces of the semiconductor chip. The through-electrodes are disposed within the through-holes. The current leakage prevention layer covers the polarized part and exposes ends of the through-electrodes.

A semiconductor apparatus includes a first chip comprising a first bonding pad and a dielectric layer exposes a portion of the first bonding pad; a first bonding layer covering entirely or partially the first front side of the first chip, a second chip comprising a second bonding pad and a through-silicon via, and a conductive projection formed over the second bonding pad. The dielectric layer is formed on of the first chip, a second back side of the second chip is bonded to the first front side of the first chip by the medium of the first bonding layer, and the second bonding pad formed on a second front side of the second chip is coupled to the first bonding pad by the through-silicon via.

A method for fabricating a via hole includes forming a first mask pattern on a first surface of a wafer exposing a portion of the first surface of the wafer, forming a passivation region within the wafer by implanting impurities into the exposed portion of the wafer using the first mask pattern as an ion implantation barrier layer, forming an etching stop layer on the first surface of the wafer including the passivation regions, forming a second mask pattern on a second surface of the wafer faces away from the first surface of the wafer, wherein the second mask pattern exposes a portion of the second surface of the wafer over an area between the passivation regions, and forming a via hole by etching the wafer using the second mask pattern as an etching mask.

A semiconductor package includes a plurality of stacked semiconductor chips and a filling material. Each of the stacked semiconductor chips includes a semiconductor substrate having a first surface and a second surface, wherein a circuit pattern such as a bonding pad is formed on the first surface, and a first align pattern formed on the first surface of the semiconductor substrate, wherein the first align pattern is formed of a magnetic material. The filling material fills a gap between the semiconductor chips.
