Abstract
A semiconductor package is provided with an internal package formed in the cavity of the external leadless leadframe package (LLP). The internal package is a leadless leadframe package and provides a substrate for mounting one or more die and passive devices to form the external LLP. By arranging the die and passive components on the internal package, higher chip density and a smaller form factor may be achieved.
