Hybrid core substrate with embedded components

A hybrid core substrate, comprising:

• a rigid core having a top surface and a bottom surface, the rigid core remains as a permanent structural element of the hybrid core substrate after fabrication;
• a first laminate layer structure having a top surface and a bottom surface, the first laminate layer structure disposed above and mounted to the top surface of the rigid core, the first laminate layer structure comprising a first plurality of laminate layers stacked vertically, each laminate layer of the first plurality of laminate layers comprising a metallization structure, and the first laminate layer structure comprising a cavity in which a first component is embedded;
• a second laminate layer structure, disposed above and mounted to a top surface of the first laminate layer structure, the second laminate layer structure comprising a second plurality of laminate layers stacked vertically, each laminate layer of the second plurality of laminate layers comprising a metallization structure, the second laminate layer structure having at least one electrical connection to the first laminate layer structure and at least one electrical connection to the first component;
• a first plurality of contacts disposed on the top surface of the second laminate layer structure and electrically connected to the second laminate layer structure;
• and
• a bonding layer comprising pre-preg, the bonding layer disposed between the rigid core and the first laminate layer structure.
