20140084413 | PACKAGE SUBSTRATE AND METHOD OF FABRICATING THE SAME - A package substrate and a method of fabricating the package substrate are provided. The package substrate includes a substrate having a top surface and a bottom surface opposing the top surface; an insulating protective layer formed on the top surface of the substrate; an interposer embedded in and exposed from the insulating protective layer; and passive components provided on or embedded in the interposer. By integrating the passive components into the package substrate, when a chip is provided on the interposer, the conductive path between the chip and the passive components can be shortened, and the pins of the chip have a stable voltage. Therefore, the overall electrical performance is enhanced. | 03-27-2014 |
20140102777 | PACKAGE SUBSTRATE AND METHOD OF FABRICATING THE SAME - A package substrate and a method of fabricating the package substrate are provided. The package substrate may include an interposer having at least one conductive through via, a photo-sensitive dielectric layer formed on one side of the interposer, and at least one conductive via formed in the photo-sensitive dielectric layer and electrically connected to the conductive through via. By means of a photo lithography process with high alignment accuracy, at least one via with an extremely small diameter can be formed on the photo-sensitive dielectric layer and align with the conductive through via. Therefore, the conductive through via can have its diameter reduced as required, without considering the alignment with the at least one via. Accordingly, the interconnection density of the conductive through via on the interposer is increased. | 04-17-2014 |
20140117557 | PACKAGE SUBSTRATE AND METHOD OF FORMING THE SAME - A package substrate and a method for forming the package substrate are disclosed. The package substrate includes an interposer having a plurality of conductive through vias and a first insulating layer formed on the sidewalls of the conductive through vias, a second insulating layer formed on one side of the interposer, and a plurality of conductive vias formed in the second insulating layer and electrically connected to the conductive through vias. By increasing the thickness of the first insulating layer, the face diameter of the conductive through vias can be reduced, and the layout density of the conductive through vias in the interposer can thus be increased. | 05-01-2014 |
