Abstract
An integrated circuit (IC) package, device, including a substrate having a top surface with an IC die mounting area and a peripheral area surrounding the mounting area, a plurality of parallel conductor layers, a plurality of insulating layers and a plurality of plated through holes (PTHs) extending through the conductor layers and insulating layers. Various substrate structures in which certain of the PTHs and/or conductor layers and/or insulating layers have different CTE's than the others is disclosed. The various structures may reduce circuit failures due to substrate warpage and/or solder joint damage associated with a CTE mismatch between the substrate and the IC die.
