Abstract:
Methods for making, and structures so made for producing integrated circuit (IC) chip packages without forming micro solder balls. In one embodiment, a method may include placing a solid grid made from an organic material between the IC chip and the substrate. The grid provides a physical barrier between each of a plurality of Controlled Collapse Chip Connections, and thereby prevents the formation of micro solder balls between them, thus improving chip performance and reliability.
