Abstract

An integrated circuit package includes a balanced-part structure. The condition of thermal stress of chips connected on a substrate decides the amount, locations, weights, and the material of at least a balanced-part fastened on a substrate. The balanced-part is fastened on the substrate to balance stress distribution before an adhering heat sinks process and a packaging molding compound process. The balanced-part also decreases thermal stress affection and avoid warpage defects of the integrated circuit packages.
