RAISED PEDESTAL RADIATION SHIELD FOR SENSITIVE ELECTRONICS

摘要

A radiation shield (10) for protecting an integrated circuit device (12) from harmful radiation has a high Z shielding material for absorbing radiation. The radiation shield has a planar lower surface (18) in contact with an upper surface of the integrated circuit device. The radiation shield also has a central portion (14) in a substantial registration with integrated cicuit device. The central portion has a thickness sufficient to absorb harmful radiation. A distal portion (20) is located about the central portion. A transitional portion (26) is located between and connects the central and distal portions. The transitional portion has a minimum thickness, as, measured from the integrated circuit, that is about equal to the thickness of the central portion.
