Abstract: A method for fabricating a carrier-free semiconductor package includes: half-etching a metal carrier to form a plurality of recess grooves and a plurality of metal studs each serving in position as a solder pad or a die pad; filing each of the recess grooves with a first encapsulant; forming on the metal studs an antioxidant layer such as a silver plating layer or an organic solderable protection layer; and performing die-bonding, wire-bonding and molding processes respectively to form a second encapsulant encapsulating the chip.

A method for using a DNA kit comprises the following steps: collecting DNA from a collection portion of the foldable collection rod of the DNA collection kit; breaking the foldable collection rod from the groove of the rod body to obtain a DNA-comprising collection portion; and putting the DNA-comprising collection portion into the collection bottle comprising the buffer to prolong the preservation time of the DNA, wherein the buffer comprises ethylenediamine tetraacetic acid (EDTA) at a concentration from 20 mM to 60 mM.

Abstract: A method of fabricating a semiconductor package is provided, including: providing a heat dissipating structure having a heat dissipating portion, a deformable supporting portion coupled to the heat dissipating portion, and a coupling portion coupled to the supporting portion; coupling a carrier having a semiconductor element carried thereon to the coupling portion of the heat dissipating structure to form between the carrier and the heat dissipating portion a receiving space for the semiconductor element to be received therein; and forming in the receiving space an encapsulant that encapsulates the semiconductor element. The use of the supporting portion enhances the bonding between the heat dissipating structure and a mold used for packaging, thereby preventing the heat dissipating structure from having an overflow of encapsulant onto an external surface of the heat-dissipating portion.

Abstract: A semiconductor package without a chip carrier formed thereon and a fabrication method thereof. A metallic carrier is half-etched to form a plurality of grooves and metal studs corresponding to the grooves. The grooves are filled with a first encapsulant and a plurality of bonding pads are formed on the metal studs. The first encapsulant is bonded with the metal studs directly. Each of the bonding pads and one of the metal studs corresponding to the bonding pad form a T-shaped structure. Therefore, bonding force between the metal studs and the first encapsulant is enhanced such that delamination is avoided. Die mounting, wire-bonding and molding processes are performed subsequently. Since the half-etched grooves are filled with the first encapsulant, the drawback of having pliable metallic carrier that makes transportation difficult to carry out as encountered in prior techniques is overcome, and the manufacturing cost is educed by not requiring the use of costly metals as an etching resist layer.
