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

Claim 8:
9. 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 the second semiconductor device;
a top semiconductor device above the second semiconductor device;
a thermal interface material (TIM) layer on the top semiconductor device; and
a heat dissipation member on the TIM layer;
wherein the first underfill has a first outer surface portion in a horizontal direction parallel to an upper surface of the substrate base and the second underfill has a second outer surface portion 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 surface portion is greater than a second horizontal distance from the side surface of the second semiconductor device to the second outer surface portion, and
wherein the first height is greater than the second height.
