  • Patent number: 9947606
    Abstract: A semiconductor device is disclosed including material for absorbing EMI and/or RFI. The device includes a substrate, one or more semiconductor die, and molding compound around the one or more semiconductor die. The material for absorbing EMI and/or RFI may be provided within or on a solder mask layer on the substrate, or within a dielectric core of the substrate. The device may further include EMI/RFI-absorbing material around the molding compound and in contact with the EMI/RFI-absorbing material on the substrate to completely enclose the one or more semiconductor die in EMI/RFI-absorbing material.
    Type: Grant

  • Patent number: 9337153
    Abstract: A memory device including a metallic layer shielding electromagnetic radiation and/or dissipating heat, and a method of making the memory device, are disclosed. The metallic layer is formed on a metallic layer transfer assembly. The metallic layer transfer assembly and the unencapsulated memory device are placed in a mold and encapsulated. During the encapsulation and curing of the molding compound, the metallic layer is transferred from the shield to the encapsulated memory device.

  • Patent number: 9236368
    Abstract: A semiconductor device includes a substrate (102) with a cavity (112) formed therein for receiving a semiconductor die. In examples, the semiconductor die is a controller die (114). The controller die (114) may be electrically connected to the substrate (102) with electrical traces (120) which may be formed for example by printing. After the controller die (114) is electrically connected to the substrate (102), one or more memory die (150) may be affixed to the substrate (102), over the cavity (112) and controller die (114).

  • Publication number: 20120146247
    Abstract: A memory device is disclosed including at least one surface pre-treated to roughen the surface for better adhesion of a curable fluid such as glue or ink on the surface. The surface of the memory device may be pre-treated by scoring lines in the surface with a laser or by forming discrete deformations with a particle blaster. The surface may also be roughened by providing a roughened pattern on a mold plate during an encapsulation process. In further examples, the surface may be chemically pre-treated to roughen the surface and/or increase the adhesion energy of the surface.
