Destructive system having a functional layer and an adjacent reactive layer and an associated method
View Patent ↗The invention relates to a destruction system for destroying a functional layer, which may receive data or perform other functions, such as optical functions, for example, and a related method. The reactants may be interspersed within the functional layer or may be provided in a separate layer adjacent to the functional layer. The reactants are structured to be ignited to destroy the functionality of the functional layer and the data. Ignition may be obtained through a flame or by suitable electrical current in certain embodiments of the invention.
1. A destructive system for destroying the functionality of an integrated circuit, comprising:
a base;
an integrated circuit having a first side and an opposite second size, the first side of the integrated circuit supported by said base;
a reactive layer comprising metal and oxidizer reactants, at least one of the metal and oxidizer reactants overlying, directly contacting, and being adhered to the opposite second side of said integrated circuit, the reactive layer being deposited upon said integrated circuit; and
said reactive layer is structured to be ignited to generate an elevated temperature in order to destroy the functionality of said integrated circuit or protect said integrated circuit from theft by direct reading or by reverse engineering.
2. The destructive system of claim 1 , wherein said reactive layer is structured to be ignited to generate the elevated temperature in order to protect said integrated circuit from said theft by reverse engineering.
