Radiation shielded semiconductor package

A radiation shielded semiconductor package, comprising:

• a shielding base manufactured from a high Z material;
• a non-shielding sidewall coupled to the shielding base;
• a radiation shielding flange manufactured from a high Z material coupled to the sidewall;
• a non-shielding coupling flange coupled to the shielding flange, wherein the base, the non-shielding sidewall, the shielding flange, and the non-shielding coupling flange define a device cavity;
• at least one semiconductor device positioned within the device cavity;
• and
• a radiation shielding lid manufactured from a high Z material coupled to the coupling flange and sealing the semiconductor device within the device cavity, the shielding lid having a shielding lid body and a non-shielding lid flange coupled to the lid body and configured to couple to the coupling flange.

A method of manufacturing a radiation shielded device, comprising:

• coupling one or more non-shielding sidewalls to a shielding base;
• coupling one or more shielding flanges coupled to the sidewall;
• coupling one or more non-shielding coupling flanges coupled to the shielding flange, wherein the base, the non-shielding sidewall, the shielding flange, and the non-shielding coupling flange define a device cavity;
• positioning at least one semiconductor device positioned within the device cavity;
• and
• coupling a radiation shielding lid to the coupling flange thereby sealing the semiconductor device within the device cavity, the shielding lid having a shielding lid body and a non-shielding lid flange coupled to the lid body and configured to couple to the coupling flange.
