Abstract

A chip level package utilizing a CGA is described. A semiconductor chip with pillars is molded in an encapsulant. Solder balls are added and connected to the chip pillars. The final package does not require a first level substrate or interposer and is able to be assembled to the next level as is. An additional embodiment describes the addition of a thermal heat sink to the packaged chip.
