An integrated circuit is provided with shielding means to protect it from bombardment by alpha particles and other ionizing radiation, so as to avoid errors in the functioning of the integrated circuit by the sudden introduction of electrical charge attendant upon the incidence of such radiation. The shielding means is in the form of a semiconducting layer, of the type of material which itself might be used for the fabrication of an integrated circuit, said layer being located in a close, overlapping manner relative to the fabricated area of the semiconducting lamina on which the integrated circuit, (116) to be protected, is situated, so sandwiching the integrated circuit between two layers of material which are thick enough to prevent the through-passage of high energy alpha particles, and which, by their purity, are substantially free from any radioactive inclusions. |
