Patent attributes
A semiconductor device package includes a substrate, at least one component, a package body, a first conductive layer, a first shielding layer, a second shielding layer and a second conductive layer. The component is disposed on a first surface of the substrate. The package body is disposed on the first surface of the substrate and covers the component. The first conductive layer covers the package body and at least a portion of the substrate. The first shielding layer covers the first conductive layer and has a first thickness and includes a high conductivity material. The second shielding layer covers the first shielding layer and has a second thickness and includes a high permeability material. A ratio of the first thickness to the second thickness being in a range of 0.2 to 3. The second conductive layer covers the second shielding layer.
