    Abstract: A method of fabricating a semiconductor integrated circuit device uses a mold which is provided with a plurality of air vents and movable pins which are formed such that the movable pins include grooves in the distal ends thereof which project into the air vents. By clamping the mold in a state such that the distal ends of the movable pins are pushed against a multi-cavity board at the time of clamping the mold, resin can be filled while leaking air inside the cavity through the grooves formed in the distal ends of the movable pins by setting the depths of the respective air vents to a fixed value irrespective of the irregularities in thickness of the multi-cavity boards. Accordingly, it is possible to prevent insufficient filling of resin in the cavity, the leaking of resin or defective welding, whereby the yield rate of products can be enhanced.

  • Publication number: 20100230808
    Abstract: The present invention relates to a semiconductor component that has a substrate and a projecting electrode. The projecting electrode has a substrate face, which faces the substrate and which comprises a first substrate-face section separated from the substrate by a gap. The gap allows a stress-compensating deformation of the projecting electrode relative to the substrate. The substrate face of the projecting electrode further comprises a second substrate-face section, which is in fixed mechanical and electrical connection with the substrate. Due to a smaller footprint of mechanical connection between the projecting electrode and the substrate, the projecting electrode can comply in three dimensions to mechanical stress exerted, without passing the same amount of stress on to the substrate, or to an external substrate in an assembly. This results in an improved lifetime of an assembly, in which the semiconductor component is connected to an external substrate by the projecting electrode.

  • Publication number: 20100178734
    Abstract: A leadless semiconductor package with an electroplated layer embedded in an encapsulant and its manufacturing processes are disclosed. The package primarily includes a half-etched leadframe, a chip, an encapsulant, and an electroplated layer. The half-etched leadframe has a plurality of leads and a plurality of outer pads integrally connected to the leads. The encapsulant encapsulates the chip and the leads and has a plurality of cavities reaching to the outer pads to form an electroplated layer on the outer pads and embedded in the cavities. Accordingly, under the advantages of lower cost and higher thermal dissipation, the conventional substrates and their solder masks for BGA (Ball Grid Array) or LGA (Land Grid Array) packages can be replaced. The leads encapsulated in the encapsulant have a better bonding strength and the electroplated layer embedded in the encapsulant will not be damaged during shipping, handling, or storing the semiconductor packages.
