Three dimensional package and packaging method for integrated circuits

摘要

A 3D package has: a three-dimensional (3D) package substrate, a land grid array (LGA) or quad flat no-lead (QFN) package mounted on the 3D package substrate, the LGA or QFN package having an LGA or QFN die on a first side of an LGA or QFN package substrate, and a second die mounted directly on a second side of the LGA or QFN package substrate opposite the first side.
