BUMP STRUCTURES FOR MULTI-CHIP PACKAGING

摘要

A multi-chip package includes a substrate having a plurality of first bump structures. A pitch between first bump structures of the plurality of first bump structures is uniform across a surface of the substrate. The multi-chip package includes a first chip bonded to the substrate and a second chip bonded to the substrate. The first chip includes a plurality of second bump structures, and the plurality of second bump structures are bonded to a first set of first bump structures of the plurality of first bump structures. The second chip includes a plurality of third bump structures, and the plurality of third bump structures are bonded to a second set of first bump structures of the plurality of first bump structures. A pitch between second bump structures of the plurality of second bump structures is different from a pitch between third bump structures of the plurality of third bump structures.

主权项

1. A multi-chip package comprising:
a substrate having a plurality of first bump structures, wherein a pitch between adjacent first bump structures of the plurality of first bump structures is uniform across a surface of the substrate; a first chip bonded to the substrate, wherein the first chip comprises a plurality of second bump structures, and the plurality of second bump structures are bonded to a first set of first bump structures of the plurality of first bump structures; and a second chip bonded to the substrate, wherein the second chip comprises a plurality of third bump structures, and the plurality of third bump structures are bonded to a second set of first bump structures of the plurality of first bump structures, wherein a pitch between adjacent second bump structures of the plurality of second bump structures is different from a pitch between adjacent third bump structures of the plurality of third bump structures.
