PROBLEM TO BE SOLVED: To provide a self-destructing chip including a first die and a second die.SOLUTION: A first die includes an electronic circuit, and a second die is composed of one or more polymers that disintegrate at a first temperature. The second die defines a plurality of chambers, where a first subset of the chambers contains a material that reacts with oxygen in an exothermic manner. A second subset of the chambers contains an etchant for etching materials of the first die. In response to a trigger event, the electronic circuit is configured to expose the material in the first subset of chambers to oxygen in order to heat the second die to at least the first temperature, and is configured to release the etchant from the second subset of the chambers to etch the first die.SELECTED DRAWING: None |
