Patents by Inventor YouJoung Choi

YouJoung Choi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240128201
    Abstract: A semiconductor device has a substrate and an electrical component disposed over a surface of the substrate. An antenna interposer is disposed over the substrate. A first encapsulant is deposited around the antenna interposer. The first encapsulant has a high dielectric constant. The antenna interposer has a conductive layer operating as an antenna and an insulating layer having a low dielectric constant less than the high dielectric constant of the first encapsulant. The antenna interposer is made from an antenna substrate having a plurality of antenna interposers. Bumps are formed over the antenna substrate and the antenna substrate is singulated to make the plurality of antenna interposers. A second encapsulant is deposited over the electrical component. The second encapsulant has a low dielectric constant less than the high dielectric constant of the first encapsulant. A shielding layer is disposed over the second encapsulant.
