The first PCB includes N vias, first ends of the N vias are located at a top layer of the PCB, and second ends of the N vias are located at a bottom layer of the first PCB. The chip is coupled to the top layer of the first PCB through N power supply contacts and the first ends of the N vias. The inductor module is coupled to the chip through M power supply contacts and the second ends of M vias of the N vias. The power controller is coupled to the inductor module through the first PCB, and the power controller is configured to control the inductor module to supply power to the chip.

An integrated circuit (IC) package including ICs with multi-row columnar die interconnects has increased die-to-die (D2D) interconnect density in a conductive layer. Positioning the die interconnects in die interconnect column clusters, that each include a plurality of die interconnect rows and two columns, reduces the linear dimension occupied by the die interconnects and leaves room for more D2D interconnects. A die interconnect column cluster pitch is a distance between columns of adjacent die interconnect column clusters and this distance is greater than a die interconnect pitch between columns within the column clusters. Die interconnects may be disposed in the space between the multi-row column clusters and additional die interconnects can be disposed at the D2D interconnect pitch between the die interconnect column clusters. IC packages with ICs including the multi-row columnar die interconnects have a greater number of D2D interconnects for better IC integration.

A semiconductor device assembly that includes a substrate having a first side and a second side, the first side having at least one dummy pad and at least one electrical pad. The semiconductor device assembly includes a first semiconductor device having a first side and a second side and at least one electrical pillar extending from the second side. The electrical pillar is connected to the electrical pad via solder to form an electrical interconnect. The semiconductor device assembly includes at least one dummy pillar extending from the second side of the first semiconductor device and a liquid positioned between an end of the dummy pillar and the dummy pad. The surface tension of the liquid pulls the dummy pillar towards the dummy pad. The surface tension may reduce or minimize a warpage of the semiconductor device assembly and/or align the dummy pillar and the dummy pad.
