Patent ID: 7382043

Claim:
A radiation shielding integrated circuit device comprising: a die of an electronic circuit device; an x-ray shielding tub comprising a bottom portion and sidewalls extending from the bottom portion, the die being disposed on the bottom portion between the sidewalls; a base coupled to the bottom portion of the x-ray shielding tub opposite the die; and a radiation shielding lid coupled to the base; wherein the radiation shielding lid and the x-ray shielding tub are positioned to shield the die from x-rays from every angle, whereby the die is shielded from receiving from all directions an amount of radiation greater than a total dose tolerance of the die; and the radiation shielding lid is not in direct contact with the x-ray shielding tub so that the radiation shielding lid and the x-ray shielding tub do not completely enclose the die.
