ABSTRACT:
An apparatus for heatsink attachment and a method for forming the apparatus. The apparatus includes a substrate, a semiconductor chip on top of and physically attached to the substrate, and a lid on top of the substrate. The lid includes a first thermally conductive material. The apparatus further includes a heatsink on top of the lid. The heatsink includes a second thermally conductive material. The semiconductor chip and the substrate share a common interface surface that defines a reference direction perpendicular to the common interface surface and pointing from the substrate towards the semiconductor chip. The lid is disposed between the substrate and the heatsink. The lid includes a first protruding member. The first protruding member of the lid is farther away from the substrate than a portion of the heatsink in the reference direction.
