A semiconductor device package having a thermal dissipation feature is provided. The semiconductor device package includes a package substrate. A semiconductor die is mounted on a first surface of the package substrate. A thermal conductive structure including a die pad portion is affixed to the semiconductor die. A limb portion of the thermal conductive structure extends laterally away from the die pad portion and overlaps a portion of the package substrate. A thermal conduction path is formed between the semiconductor die and a distal end of the limb portion.

Semiconductor device package having thermal dissipation feature and method therefor

A method of tie bar removal is provided. The method includes forming a leadframe including a tie bar and a flag. The tie bar extends from a side rail of the leadframe and has a distal portion at an angle different from a plane of the flag. A semiconductor die is attached to the flag of the leadframe. A molding compound encapsulates the semiconductor die, a portion of the leadframe, and the distal portion of the tie bar. The tie bar is separated from the molding compound with an angled cavity remaining in the molding compound.

Tie bar removal for semiconductor device packaging

A cost-effective process and structure is provided for a thermal dissipation element for semiconductor device packages incorporating antennas that can incorporate RF/EMI shielding from the antenna elements. Certain embodiments provide incorporated antenna element structures as part of the same process. These features are provided using a selectively-plated thermal dissipation structure that is formed to provide shielding around semiconductor device dies that are part of the package. In some embodiments, the thermal dissipation structure is molded to the semiconductor device, thereby permitting a thermally efficient close coupling between a device die requiring thermal dissipation and the dissipation structure itself.

Semiconductor package thermal spreader having integrated EF/EMI shielding and antenna elements

A semiconductor device package having a thermal dissipation feature is provided. The semiconductor device package includes a package substrate. A semiconductor die is mounted on a first surface of the package substrate. A first conductive connector is affixed to a first connector pad of the package substrate. A conformal thermal conductive layer is applied on the semiconductor die and a portion of the first surface of the package substrate. The conformal thermal conductive layer is configured and arranged as a thermal conduction path between the semiconductor die and the first conductive connector.
