Claim:
1. A method for fabricating a self-destructive electronic chip, comprising: obtaining a structure including a semiconductor layer and an electrically insulating layer adjoining the semiconductor layer; forming electronic circuitry on the semiconductor layer; forming a triggering circuit including a normally-OFF heterojunction field-effect photo-transistor on the structure; forming a reactive layer underneath the electrically insulating layer of the structure for disabling the electronic circuitry, the reactive layer being directly or indirectly reactive to current flowing through the normally-OFF heterojunction field-effect photo-transistor; forming at least one actuating element electrically connected to the normally-OFF heterojunction field-effect photo-transistor, the actuating element being configured to cause the reactive layer to undergo a chemical reaction; forming an antenna underneath the electrically insulating layer for transmitting and/or receiving signals, the antenna being electrically connected to the electronic circuitry, and forming an encapsulation layer encapsulating the reactive layer and the antenna.
