The present invention provides a package structure and fabrication method thereof. The method includes providing a first carrier having a metal layer; forming a dielectric layer on the metal layer; forming a plurality of conductive pillars embedded into the dielectric layer and protruding from a surface of the dielectric layer, and disposing an electronic component on the surface of the dielectric layer; forming an encapsulating layer on the dielectric layer to encompass the plurality of conductive pillars, the dielectric layer and the electronic component; removing a portion of the encapsulating layer and the first carrier such that two ends of each of the plurality of conductive pillars are exposed from the encapsulating layer and the dielectric layer. Therefore, the present invention effectively reduces manufacturing costs and the need for an opening process while manufacturing the conductive pillars can be eliminated.

Package structure and fabrication method thereof

A method for fabricating a package structure is provided, which includes: providing a first carrier having a circuit layer thereon; forming a plurality of conductive posts on the circuit layer and disposing at least an electronic element on the first carrier; forming an encapsulant on the first carrier to encapsulate the conductive posts, the circuit layer and the electronic element; and removing the first carrier, thereby dispensing with the conventional hole opening process for forming the conductive posts and hence reducing the fabrication costs.

A semiconductor package is disclosed, which includes: a carrier having at least an opening; a plurality of conductive traces formed on the carrier and in the opening; a first semiconductor element disposed in the opening and electrically connected to the conductive traces; a second semiconductor element disposed on the first semiconductor element in the opening; and a redistribution layer structure formed on the carrier and the second semiconductor element for electrically connecting the conductive traces and the second semiconductor element. Since the semiconductor elements are embedded and therefore positioned in the opening of the carrier, the present invention eliminates the need to perform a molding process before forming the redistribution layer structure and prevents the semiconductor elements from displacement.

Fabrication method of semiconductor package having embedded semiconductor elements

Disclosed is a method for fabricating a semiconductor package, including providing a package unit having an insulating layer and at least a semiconductor element embedded into the insulating layer, wherein the semiconductor element is exposed from the insulting layer and a plurality of recessed portions formed in the insulating layer; and electrically connecting a redistribution structure to the semiconductor element. The formation of the recessed portions release the stress of the insulating layer and prevent warpage of the insulating layer from taking place.

Method for fabricating semiconductor package

Semiconductor package having embedded semiconductor elements

A semiconductor package and a method of manufacturing the same are provided, the semiconductor package including a first package unit having a first encapsulant and a first semiconductor element, a second package unit having a second encapsulant and a second semiconductor element, a supporting member interposed between the first and second encapsulant, a plurality of conductors penetrating the first encapsulant, the supporting member and the second encapsulant, and redistribution structures disposed on the first and second encapsulants, wherein the first and second encapsulants are coupled with each other by the supporting member to provide sufficient support and protection to enhance the structure strength of the first and second package units.

Semiconductor package and method of manufacturing the same

A method of fabricating a semiconductor package is provided, including: disposing a semiconductor element on a carrier; forming an encapsulant on the carrier to encapsulant the semiconductor element; forming at least one through hole penetrating the encapsulant; forming a hollow conductive through hole in the through hole and, at the same time, forming a circuit layer on an active surface of the semiconductor element and the encapsulant; forming an insulating layer on the circuit layer; and removing the carrier. By forming the conductive through hole and the circuit layer simultaneously, the invention eliminates the need to form a dielectric layer before forming the circuit layer and dispenses with the conventional chemical mechanical polishing (CMP) process, thus greatly improving the fabrication efficiency.

Method of fabricating a semiconductor package

A lead frame structure is provided, which includes a die pad having a first mounting portion and a second mounting portion separated from the first mounting portion by a gap. The first and second mounting portions are formed with corresponding blocking surfaces bordering the gap, so as to allow a flow rate of an encapsulating resin flowing through the gap during a molding process to be reduced by the blocking surfaces, such that different portions of the encapsulating resin respectively flowing above, in and below the die pad can have substantially the same flow rate, thereby preventing bonding wires from being deformed to cause short circuit and avoiding formation of voids. A semiconductor package with the lead frame structure is also provided.
