Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor die (die) package comprising;
a substrate having one or more substrate layers, one or more of the substrate layers having one or more substrate connections, the substrate connections being one of a substrate horizontal connection and a substrate via connections, the substrate having a top substrate layer and a bottom substrate layer;
one or more redistribution layers (RDLs), the RDLs being one of the substrate layers, the RDLs having one or more RDL connections, the RDL connections being one of a RDL horizontal connection being one of the substrate horizontal connections and a RDL via connections being of the substrate via connections;
one or more dies disposed on the top substrate layer, each of the dies having one or more die external connections, one or more of the die external connections being electrically connected to one or more of the substrate connections, being corresponding substrate connections; and
one or more metallic dam stiffeners, the metallic dam stiffeners connected to form a metallic dam enclosure, the metallic dam enclosure disposed on and physically attached to the top substrate layer, the metallic dam enclosure enclosing one or more of the dies, the metallic dam enclosure having one or more electrically connected regions where the metallic dam enclosure is electrically and physically connected to one or more of the substrate horizontal connections and one or more electrically insulated regions where the metallic dam enclosure is electrically insulated from but physically connected to one or more of the substrate horizontal connections and the substrate via connections.
