20140021629 | SEMICONDUCTOR PACKAGE AND METHOD OF FABRICATING THE SAME - A method of fabricating a semiconductor package is provided, including: disposing a plurality of semiconductor elements on a carrier through an adhesive layer in a manner that a portion of the carrier is exposed from the adhesive layer; forming an encapsulant to encapsulate the semiconductor elements; removing the adhesive layer and the carrier to expose the semiconductor elements; and forming a build-up structure on the semiconductor elements. Since the adhesive layer is divided into a plurality of separated portions that will not affect each other due to expansion or contraction when temperature changes, the present invention prevents positional deviations of the semiconductor elements during a molding process, thereby increasing the alignment accuracy. | 01-23-2014 |
20140191376 | SEMICONDUCTOR PACKAGE AND FABRICATION METHOD THEREOF - A semiconductor package is provided, including: a substrate; a first semiconductor element disposed on the substrate and having a first conductive pad grounded to the substrate; a conductive layer formed on the first semiconductor element and electrically connected to the substrate; a second semiconductor element disposed on the first semiconductor element through the conductive layer; and an encapsulant formed on the substrate and encapsulating the first and second semiconductor elements. Therefore, the first and second semiconductor elements are protected from electromagnetic interference (EMI) shielding with the conductive layer being connected to the grounding pad of the substrate. A fabrication method of the semiconductor package is also provided. | 07-10-2014 |
20150014848 | SEMICONDUCTOR DEVICE AND FABRICATION METHOD THEREOF - A semiconductor device is disclosed, which includes: a substrate having a substrate body and a plurality of conductive pads formed on the substrate body, wherein each of the conductive pads has at least an opening formed in a first surface thereof; a semiconductor component having a plurality of bonding pads; a plurality of conductive elements formed between the bonding pads and the conductive pads and in the openings of the conductive pads; and an encapsulant formed between the substrate and the semiconductor component for encapsulating the conductive elements, thereby strengthening the bonding between the conductive elements and the conductive pads and consequently increasing the product yield. | 01-15-2015 |
20150069605 | SEMICONDUCTOR DEVICE AND FABRICATION METHOD THEREOF AND SEMICONDUCTOR STRUCTURE - A semiconductor device is disclosed, which includes: a substrate having a plurality of connecting pads; a semiconductor component having a plurality of bonding pads formed on a surface thereof and corresponding to the connecting pads and a UBM layer formed on the bonding pads; a plurality of conductive elements each having a first conductive portion and a second conductive portion sequentially formed on the UBM layer, wherein the second conductive portion is less in width than the first conductive portion; and a plurality of solder balls formed between the second conductive portions and the connecting pads for connecting the semiconductor component and the substrate, thereby preventing solder bridging from occurring between the adjacent conductive elements and reducing stresses between the conductive elements and the UBM layer. | 03-12-2015 |
20150235914 | FLIP-CHIP PACKAGING SUBSTRATE, FLIP-CHIP PACKAGE AND FABRICATION METHODS THEREOF - A flip-chip packaging substrate is provided, which includes: a substrate body; a plurality of conductive pads formed on a surface of the substrate body; an insulating layer formed on the surface of the substrate body and having a plurality of openings correspondingly exposing a portion of each of the conductive pads; and a metal layer formed on each of the conductive pads in the openings, wherein the metal layer has a top surface having a lowest point lower than a top surface of the insulating layer, and a thickness ratio of the metal layer to the insulating layer is greater than or equal to 1/4 and less than 1, thereby preventing a solder bridge or short circuit from occurring. | 08-20-2015 |
20150237717 | PACKAGE SUBSTRATE AND STRUCTURE - A package substrate is provided, which includes a plurality of dielectric layers and a plurality of circuit layers alternately stacked with the dielectric layers.
