Patent ID: 8178964

Claim:
A structure of semiconductor device package comprising: a substrate with a die receiving through hole, a connecting through hole structure and a first contact pad; a die disposed within said die receiving through hole; a core paste formed under said die and filled in the gap between said die and sidewall of said die receiving through hole; a first re-distribution layer (RDL) formed above said die and said substrate and coupled to said first contact pad and wherein said first re-distribution layer fans out from said die; a first dielectric layer formed on said die and said substrate, wherein said first RDL formed on said first dielectric layer; a second contact pad formed at the lower surface of said substrate; and a second re-distribution layer (RDL) formed under said substrate and coupled to said second contact pad; wherein the material of said first RDL or said second RDL comprises Ti/Cu/Au alloy or Ti/Cu/Ni/Au alloy.
