Patent ID: 8339797

Claim:
A package substrate comprising: a main package including: a main package body including first and second principal surfaces that are opposed to each other; a first bonding material provided on the second principal surface of the main package body; and an internal circuit provided within the main package body and electrically connected to the first bonding material; and a sub-package located on the second principal surface of the main package and including a plurality of electronic components embedded therein; wherein the sub-package includes: a sub-package body including first and second principal surfaces that are opposed to each other; a first pad conductor provided on the first principal surface of the sub-package body and electrically connected to the internal circuit of the main package and the plurality of electronic components embedded in the sub-package; and a second pad conductor provided on the second principal surface of the sub-package body and electrically connected to the plurality of electronic components embedded in the sub-package; a thickness direction dimension that is a dimension from the second principal surface of the main package to a portion of the sub-package that is most distant from the second principal surface of the main package, is substantially equal to or less than a thickness direction dimension of the first bonding material; and the second pad conductor functions together with the first bonding material as one of an input path portion to the internal circuit or an output path portion from the internal circuit.
