Abstract

The plastic encapsulation material covering an integrated circuit is impregnated with a corrosion inhibitor evenly dispensed throughout the material. This inhibits the corrosion of the metallization on the surface of the integrated circuit thus prolonging the life of the device particularly under adverse environmental conditions.
