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.

The embodiments described provide elongated bonded structures near edges of packaged structures free of solder wetting on sides of copper posts substantially facing the center of the packaged structures. Solder wetting occurs on other sides of copper posts of these bonded structures. The elongated bonded structures are arranged in different arrangements and reduce the chance of shorting between neighboring bonded structures. In addition, the elongated bonded structures improve the reliability performance.
