Abstract: A three-dimensional integrated circuit includes a first die structure having a first geometry. The first die structure includes a first region that operates with a first power density and a second region that operates with a second power density. The first power density is less than the second power density. The three-dimensional integrated circuit includes a second die structure having a second geometry. A stacked portion of the second die structure is aligned with the first region. The three-dimensional integrated circuit includes an additional die structure stacked with the first die structure and the second die structure. The additional die structure has the first geometry or the second geometry.

Abstract: A chiplet system includes a central processing unit (CPU) communicably coupled to a first GPU chiplet of a GPU chiplet array. The GPU chiplet array includes the first GPU chiplet communicably coupled to the CPU via a bus and a second GPU chiplet communicably coupled to the first GPU chiplet via a passive crosslink. The passive crosslink is a passive interposer die dedicated for inter-chiplet communications and partitions systems-on-a-chip (SoC) functionality into smaller functional chiplet groupings.

Abstract: Various semiconductor chip packages are disclosed. In one aspect, a semiconductor chip package includes a package substrate that has a first side and a second side opposite to the first side. A semiconductor chip is mounted on the first side. Plural metal anchor structures are coupled to the package substrate and project away from the first side. A molding layer is on the package substrate and at least partially encapsulates the semiconductor chip and the anchor structures. The anchor structures terminate in the molding layer and anchor the molding layer to the package substrate.
