HYBRID METALLIZATION AND LAMINATE STRUCTURE

Abstract:

Conventional package problems may be overcome with a hybrid metallization and laminate structure that avoids warpage problems and size reduction problems. One example structure may include a metallization structure directly attached to an active side of a logic die stack in a core substrate (on one or both sides of the substrate) with laminate layers built-up on top of the metallization structures for a symmetrical package structure.
