    Abstract: A semiconductor device has a substrate and a first semiconductor die disposed over the substrate. A subpackage is also disposed over the substrate. A stiffener is disposed over the substrate around the first semiconductor die and subpackage. A heat spreader is disposed over the stiffener. The heat spreader is thermally coupled to the first semiconductor die. The heat spreader has an opening over the subpackage.

    Abstract: A semiconductor device has an electrical component and a first TIM with a first compliant property is disposed over a surface of the electrical component. A second TIM having a second compliant property greater than the first compliant property is disposed over the surface of the electrical component within the first TIM. A third TIM can be disposed over the surface of the electrical component along the first TIM. A heat sink is disposed over the first TIM and second TIM. The second TIM has a shape of a star pattern, grid of dots, parallel lines, serpentine, or concentric geometric shapes. The first TIM provides adhesion for joint reliability and the second TIM provides stress relief. Alternatively, a heat spreader is disposed over the first TIM and second TIM and a heat sink is disposed over a third TIM and fourth TIM on the heat spreader.
