Abstract:
The present invention provides a method of forming a chip with TSV electrode. A substrate with a first surface and a second surface is provided. A thinning process is performed from a side of the second surface so the second surface becomes a third surface. Next, a penetration via which penetrates through the first surface and the third surface is formed in the substrate. A patterned material layer is formed on the substrate, wherein the patterned material layer has an opening exposes the penetration via. A conductive layer is formed on the third surface thereby simultaneously forming a TSV electrode in the penetration via and a surface conductive layer in the opening.
Abstract:
A method for fabricating through-substrate structure is disclosed. The method includes the steps of: providing a substrate; forming a through-substrate hole and a through-substrate trench in the substrate; and forming a metal layer in the through-substrate hole and the through-substrate trench for forming a through-substrate via and a through-substrate conductor having a void therein.
Abstract:
The present disclosure relates to an interposer structure and a manufacturing method thereof. The interposer structure includes a first dielectric layer, a conductive pad, and a bump. The conductive pad is disposed in the first dielectric layer, wherein a top surface of the conductive pad is exposed from a first surface of the first dielectric layer, the conductive pad further includes a plurality of connection feet, and the connection feet protrude from a bottom surface of the conductive pad to a second surface of the first dielectric layer. The bump is disposed on the second surface of the first dielectric layer, and the bump directly contacts to the connection feet. Through the aforementioned interposer structure, it is sufficient to achieve the purpose of improving the electrical performance of the semiconductor device and avoiding the signal being loss through the TSV.
