Patent ID: 11948873
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 18:
19. A semiconductor package, comprising:
a first substrate;
a first semiconductor device on the first substrate;
an under-fill layer between the first semiconductor device and the first substrate;
a mold layer covering the first semiconductor device;
a second substrate on the mold layer;
a support solder ball interposed between the first substrate and the second substrate, and electrically disconnected from the first substrate or the second substrate, wherein the support solder ball includes a core and is disposed near a first sidewall of the first semiconductor device; and
a substrate connection solder ball disposed between the first sidewall of the first semiconductor device and the support solder ball to electrically connect the first substrate to the second substrate,
wherein the support solder ball is in contact with a top surface of the first substrate or a bottom surface of the second substrate,
a top surface of the first semiconductor device has a first height from the top surface of the first substrate,
the core has a second height greater than the first height,
the second height is measured from a bottom surface of the core to a top surface of the core, and
a difference between the second height and the first height is 10 μm to 50 μm.
