Abstract
A radiation shielded semiconductor package for use in any variety of industries and applications is disclosed. In one embodiment, a radiation shielded semiconductor package comprises a radiation shielding base, one or more non-shielding sidewalls coupled to the shielding base, one or more radiation shielding flanges coupled to the sidewall, and one or more non-shielding coupling flanges coupled to the shielding flange. The base, the non-shielding sidewall, the shielding flange, and the non-shielding coupling flange define a device cavity, and at least one semiconductor device is positioned within the device cavity. A radiation shielding lid is coupled to the coupling flange and hermetically seals the semiconductor device within the device cavity. The shielding lid comprises shielding lid body and a non-shielding lid flange coupled to the lid body and is configured to couple to the coupling flange.
