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

Claim 1:
2. A semiconductor package, comprising:
a first semiconductor device on a first redistribution substrate;
a first mold layer that covers the first semiconductor device and the first redistribution substrate; and
a second redistribution substrate on the first mold layer, the second redistribution substrate having a first opening that exposes a top surface of the first mold layer,
wherein the second redistribution substrate includes:
a first redistribution dielectric layer and a second redistribution dielectric layer that are sequentially stacked, and
first redistribution patterns between the first redistribution dielectric layer and the second redistribution dielectric layer, all the first redistribution patterns being internal within the second redistribution substrate, and

wherein a thickness of the first redistribution dielectric layer is less than a thickness of the second redistribution dielectric layer, the first redistribution dielectric layer being between the first mold layer and the second redistribution dielectric layer.
