A semiconductor device includes a substrate, an electronic component, a stiffener ring and an adhesive ring. The substrate has a first surface and a second surface opposite to the first surface. The electronic component is over the first surface of the substrate. The stiffener ring is over the first surface of the substrate. The stiffener ring includes a plurality of side parts and a plurality of corner parts coupled to the side parts. Heights of the corner parts are less than heights of the side parts. The adhesive ring is interposed between the first surface of the substrate and the stiffener ring. The adhesive ring includes a plurality of side portions and a plurality of corner portions coupled to the side portions. Thicknesses of the side portions are less than thicknesses of the corner portions.

Semiconductor device

A package includes a substrate having a conductive layer, and the conductive layer comprises an exposed portion. A die stack is disposed over the substrate and electrically connected to the conductive layer. A high thermal conductivity material is disposed over the substrate and contacting the exposed portion of the conductive layer. The package further includes a contour ring over and contacting the high thermal conductivity material.

3DIC packaging with hot spot thermal management features

A package includes a package component, a device die over and bonded to the package component, a metal cap having a top portion over the device die, and a thermal interface material between and contacting the device die and the metal cap. The thermal interface material includes a first portion directly over an inner portion of the device die, and a second portion extending directly over a corner region of the device die. The first portion has a first thickness. The second portion has a second thickness greater than the first thickness.
