Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 15:
16. A semiconductor package, comprising:
a substrate base;
a first semiconductor device connected to the substrate base by a first connection terminal;
a second semiconductor device connected to the first semiconductor device by a second connection terminal;
a first underfill having a first height between the substrate base and the first semiconductor device;
a second underfill having a second height between the first semiconductor device and second semiconductor device;
a top semiconductor device above the second semiconductor device; and
a top underfill between the second semiconductor device and the top semiconductor device;
wherein the first underfill has a first outer end in a horizontal direction parallel to an upper surface of the substrate base and the second underfill has a second outer end in the horizontal direction parallel to the upper surface of the substrate base,
a first horizontal distance from a vertical line along a side surface of the second semiconductor device to the first liter end is greater than a second horizontal distance from the side surface of the second semiconductor device to the second outer end, and
wherein the first height is greater than the second height.
