Abstract
A chip cover for complete or partial covering of electrical, electronic, optoelectronic and/or electromechanical components includes an activator capable of fully or partially destroying the electrical, electronic, optoelectronic and/or electromechanical components of the chip when activated. The activator can be activated by an attempt to remove the chip cover from the chip. In this way it is possible to reliably prevent reverse engineering and/or manipulation of the chip.
