Abstract:
A semiconductor package and related methods are described. In one embodiment, the package includes a die pad, a plurality of leads, a chip, and a package body. The die pad includes: (1) a peripheral edge region defining, a cavity with a cavity bottom including a central portion; (2) an upper sloped portion; and (3) a lower sloped portion. Each lead includes an upper sloped portion and a lower sloped portion. The chip is disposed on the central portion of the cavity bottom and is coupled to the leads. The package body is formed over the chip and the leads, substantially fills the cavity, and substantially covers the upper sloped portions of the die pad and the leads. The lower sloped portions of the die pad and the leads at least partially extend outwardly from a lower surface of the package body.
