Abstract: An electronic module is provided, which includes a first package and a second package stacked on the first package. The first package has an encapsulant and an electronic element embedded in the encapsulant. The second package has an insulating layer and an antenna structure formed on and extending through the insulating layer. The insulating layer is bonded to the encapsulant with the antenna structure being electrically connected to the electronic element. Since the second package having the antenna structure is stacked on the first package, the invention eliminates the need to increase the area of the first package for mounting the antenna structure and hence allows the electronic module to meet the miniaturization requirement.

Abstract: A semiconductor package is provided, which includes: a packaging substrate having opposite first and second surfaces and a plurality of first and second conductive pads formed on the first surface; a chip having opposite active and inactive surfaces and disposed on the first conductive pads via the active surface thereof; a plurality of conductive posts formed on the second conductive pads, respectively; and a first encapsulant formed on the first surface of the packaging substrate for encapsulating the chip and the conductive posts and having a plurality of openings for exposing upper surfaces of the conductive posts, thereby increasing the package density and protecting the chip and the interconnection structure from being adversely affected by intrusion of moisture.

Abstract: A method for fabricating a package structure is provided, which includes the steps of: providing a carrier having a plurality of bonding pads; laminating a laminate on the carrier, wherein the laminate has a built-up portion and a release portion smaller in size than the built-up portion, the release portion covering the bonding pads and the built-up portion being laminated on the release portion and the carrier; forming a plurality of conductive posts in the built-up portion; and removing the release portion and the built-up portion on the release portion such that a cavity is formed in the laminate to expose the bonding pads, the conductive posts being positioned around a periphery of the cavity. Therefore, the present invention has simplified processes.

Abstract: A package structure is disclosed, which includes: a first substrate; a build-up layer formed on and electrically connected to the first substrate and having a cavity; at least an electronic element disposed in the cavity and electrically connected to the first substrate; a stack member disposed on the build-up layer so as to be stacked on the first substrate; and an encapsulant formed between the build-up layer and the stack member. The build-up layer facilitates to achieve a stand-off effect and prevent solder bridging.

Abstract: A package substrate having landless conductive traces is proposed, which includes a core layer with a plurality of plated through holes formed therein, and a plurality of conductive traces formed on at least a surface of the core layer. Each of the conductive traces has a connection end, a bond pad end, and a base body connecting the connection end and the bond pad end, the conductive trace is electrically connected to a corresponding one of the plated through holes through the connection end, and the connection end has a width greater than that of the base body but not greater than the diameter of the plated through hole, thereby increasing the contact area between the conductive trace and the plated through hole and preventing the contact surface of the conductive trace with the plated through hole from cracking.
