A semiconductor package and a manufacturing method thereof are disclosed. The semiconductor package includes a device carrier and a stiffener structure. The device carrier includes at least one insulating layer and at least conductive layer defining at least one trace layout unit. The stiffener structure is disposed on the device carrier, surrounding the periphery of the at least one trace layout unit. The stiffener structure is disposed away from the periphery of the at least one trace layout unit, forming a cavity with the device carrier. The shape and disposition of the stiffener structure enhance the strength of the semiconductor package, impeding flexure to the semiconductor package.

Semiconductor package and manufacturing method thereof

A method for fabricating a flip-chip semiconductor package. The method comprises processing a semiconductor device, for example a semiconductor chip and processing a device carrier, for example a substrate. The semiconductor device comprises bump structures formed on a surface thereof. The substrate comprises bond pads formed on a surface thereof. Processing of the semiconductor chip results in heating of the semiconductor chip to a chip process temperature. The chip process temperature melts solder portions on the bump structures Processing of the substrate results in heating of the substrate to a substrate process temperature. The method comprises spatially aligning the semiconductor chip in relation to the substrate to correspondingly align the bump structures in relation to the bump pads. The semiconductor chip is then displaced towards the substrate for abutting the bump structures of the semiconductor chip with the bond pads of the substrate to thereby form bonds therebetween. A system for performing the above method is also disclosed.

Method for device packaging

A semiconductor substrate including a carrier, a first conductive layer and a second conductive layer is disclosed. The carrier has a first surface, a second surface, and a concave portion used for receiving a semiconductor element. The first conductive layer is embedded in the first surface and forms a plurality of electric-isolated package traces. The second conductive layer is embedded in the second surface and electrically connected to the first conductive layer. The semiconductor substrate can be applied to a semiconductor package for carrying a semiconductor chip, and combined with a filling structure for fixing the chip. Furthermore, a plurality of the semiconductor substrates can be stacked and connected via adhesive layers, so as to form a semiconductor device with a complicated structure.
