Abstract:
The present invention provides a semiconductor structure and a method of fabricating the same. The semiconductor structure includes a carrier, a semiconductor chip and an encapsulant. The semiconductor chip is disposed on the carrier, and has opposing non-active and active surfaces. The non-active surface is coupled to the carrier, and the active surface has a plurality of metallic pillars formed thereon. A under bump metallogy layer is formed between the metallic pillars and the active surface and on side surfaces of the metal pillars. The surface of the encapsulant is flush with end surfaces of the metallic pillars. Therefore, the product yield is increased significantly.
Abstract:
An interposer is provided, including a substrate body, a plurality of conductive posts formed in the substrate body, and a plurality of conductive pads formed on the substrate body and electrically connected to the conductive posts. The conductive pads and the conductive posts are integrally formed. As such, no interface is formed between the conductive pads and the conductive posts, thereby preventing delamination or cracking from occurring between the conductive pads and the conductive posts.

An electronic package is provided, which includes: a circuit structure having opposite first and second sides; at least an electronic element disposed on the first side of the circuit structure; an encapsulant formed on the first side of the circuit structure for encapsulating the electronic element; a dielectric layer formed on portions of the second side of the circuit structure; and a metal structure formed on the dielectric layer and the circuit structure. The metal structure has a first metal layer bonded to the circuit structure and a second metal layer formed on the first metal layer and the dielectric layer. Therefore, by replacing a conventional silicon interposer with the circuit structure, the invention eliminates the need to fabricate through silicon vias so as to greatly reduce the fabrication difficulty and cost. The invention further provides a method for fabricating the electronic package.

A package structure is provided, which includes: a chip carrier having a plurality of conductive connection portions; at least an electronic element disposed on the chip carrier; a plurality of conductive wires erectly positioned on the conductive connection portions, respectively; an encapsulant formed on the chip carrier for encapsulating the conductive wires and the electronic element, wherein one ends of the conductive wires are exposed from the encapsulant; and a circuit layer formed on the encapsulant and electrically connected to exposed ends of the conductive wires. According to the present invention, the conductive wires serve as an interconnection structure. Since the wire diameter of the conductive wires is small and the pitch between the conductive wires can be minimized, the present invention reduces the size of the chip carrier and meets the miniaturization requirement.

A method for fabricating an electronic package is provided, which includes the steps of: providing a substrate having a cavity and a first via hole; disposing an electronic element in the cavity; forming a dielectric layer on the substrate and the electronic element; forming a circuit layer on the dielectric layer and forming a first conductive portion in the first via hole; forming on the substrate a second via hole communicating with the first via hole, the first and second via holes constituting a through hole; and forming a second conductive portion in the second via hole, the first and second conductive portions constituting a conductor. Since the through hole is formed through a two-step process, the invention can reduce the depth of the via holes and therefore perform laser drilling or etching processes with reduced energy, thereby avoiding damage of the conductive portions and improving the product reliability.
