Abstract

A semiconductor device has a die mounted on a die paddle that is elevated above and thermally connected via tie bars to a heat sink structure. Heat generated by the die flows from the die to the die paddle to the tie bars to the heat sink structure and then to either the external environment or to an external heat sink. By elevating the die/paddle sub-assembly above the heat sink structure, the packaged device is less susceptible to delamination between the die and die attach adhesive and/or the die attach adhesive and the die paddle. An optional heat sink ring can surround the die paddle.
