20220285280 · 2022-09-08 ·

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.
