Assignee: ROCKWELL COLLINS, INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. An integrated circuit (IC) package, comprising:
at least one substrate having an upper surface and a lower surface, the upper surface and a lower surface sharing a perimeter defined by one or more edges and comprising an outer portion proximate to the perimeter and an inner portion surrounding the outer portion, the upper surface including at least one wiring layer;
at least one semiconducting die comprising 1) a bottom face bonded to the inner portion of the substrate via the wiring layer and 2) a top face disposed at a first height above the substrate;
one or more auxiliary components at least partially bonded to the outer portion of the substrate and including at least one tall component having a second height greater than the first height;
a heat spreader disposed above the top face of the at least one tall component and extending in a plane between the one or more edges of the substrate, the heat spreader having an outer side and an inner side, the inner side comprising a boss extending toward the semiconducting die and thermally coupled to the top face, the boss having a first width adjacent to the heat spreader and a second width at the point of thermal coupling to the top face, the second width greater than the first width;
and
an encapsulant configured to fill the free space between the substrate and the heat spreader.
