Abstract
An in-process structure including an interposer is provided. The interposer includes first interposer bonding pads. An array of copper pillar structures is bonded to the first interposer bonding pads using interposer-side solder material portions. A packaging substrate is attached to the array of copper pillar structures by bonding the array of copper pillar structures to substrate bonding pads located on the packaging substrate using substrate-side solder material portions.
