Abstract:
A radiation shielded integrated circuit device comprising:an integrated circuit die; a first layer of shielding material supporting the integrated circuit die, the first layer having a central portion having a first thickness and having an area at least as large as the area of the IC die, and an outer portion having a second thickness less than the first thickness; a wall of ceramic material having a first edge connected to the outer portion of the first layer of shielding material and a second edge, the wall of ceramic material having an inner surface defining, in conjunction with the first layer of shielding material, a well containing the integrated circuit die; a plurality of wire bond pads supported by the inner surface of the ceramic wall; a plurality of input/output pads connected to an exterior surface of the ceramic walls; conducting material extending through the ceramic material, connecting each of the wire bond pads to a respective one of input/output pads; wire bonds connecting the integrated circuit die to the wire bond pads; and a second layer of shielding material connected to the second edge of the ceramic wall.
