Abstract
The present invention provides an integrated circuit chip having one or more circuit elements that perform a desired circuit function with the circuit elements being encompassed by a molding compound that forms a package for the chip. The molding compound has a capacitance associated with it. The integrated circuit chip includes a second integrated circuit element within the molding compound in which the second integrated circuit element monitors the molding compound to detect a change in capacitance in the molding compound resulting from a removal of a portion or all of the molding compound. In response to a detection of a change in capacitance, the second integrated circuit element alters the desired circuit function provided by the other integrated circuit elements.
