Assignee: AMKOR TECHNOLOGY SINGAPORE HOLDING PTE. LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A semiconductor package comprising:
a substrate comprising:
a first land having a first land section comprising a first part proximate to a first surface of the substrate and extending to a second part internal to the first land, the first land comprising a second land section comprising a third part proximate to a second surface of the substrate and extending to the second part;
a second land having a second land wide portion and second land narrow portion; and
a first mold layer disposed adjacent to and directly contacting the first land section and the second land narrow portion,

wherein:
the first land section has a first height;
the second land section has a second height different than the first height;
the first land section comprises a first width in a first cross-sectional view; and
the second land section comprises a second width in the first cross-sectional view;

a semiconductor device coupled with a first conductive bump to the second land section and coupled with a second conductive bump to the second land wide portion,
wherein:
at least a portion of the first land section is disposed outside a perimeter of the semiconductor device in a second cross-sectional view;
the first land section comprises a first narrowest dimension in the first cross-sectional view parallel to the first width;
the second land section comprises a second narrowest dimension in the first cross-sectional view parallel to the second width; and
the first narrowest dimension is less than the second narrowest dimension; and

a mold member encapsulating at least portions of the semiconductor device; wherein:
the mold member comprises a bottom side;
the first mold layer comprises a top side; and
the top side of the first mold layer adjoins the bottom side of the mold member at location where the second land wide portion meets the second land narrow portion and the first land section meets the second land section.
