  • Patent number: 8525318
    Abstract: Disclosed are a semiconductor device capable of efficiently radiating heat of a semiconductor die and a method of fabricating the same. The semiconductor device efficiently radiates the heat by preventing an encapsulant from reaching the semiconductor die by an encapsulant dam so that an upper surface of the semiconductor die is exposed out of the encapsulant. In addition, the semiconductor device is configured to expose a pre-solder ball or a conductive pattern of a substrate through a via of the encapsulant. Therefore, electrical connection between the pre-solder ball and a solder ball of another semiconductor device stacked thereon is easily achieved.

  • Patent number: 8362598
    Abstract: In accordance with the present invention, there is provided a quad flat no leads (QFN) semiconductor device or package including a leadframe wherein the leads of the leadframe are selectively formed so that portions one or more prescribed leads are exposed in a package body of the semiconductor package and electrically connected to an electromagnetic interference (EMI) shielding layer applied to the package body. In certain embodiments of the present invention, one or more tie bars of the leadframe may also be formed so as to be exposed in the package body of the semiconductor package and electrically connected to the shielding layer applied to the package body. Thus, in the present invention, the shielding layer may be electrically connected to one or more leads alone or in combination with one or more tie bars of the leadframe.
