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

Claim 0:
1. 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 between the substrate base and the first semiconductor device; and
a second underfill between the first semiconductor device and the second 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 outer end is greater than a second horizontal distance from the side surface of the second semiconductor device to the second outer end, and
the first underfill has a first height ranging from about 5 μm to about 100 μm between the substrate base and the first semiconductor device, the second underfill has a second height of about 5 μm or greater and less than about 100 μm between the first semiconductor device and second semiconductor device, and the first height is greater than the second height.
