An electronic device includes at least one terminal formed on the electronic device. The electronic device also includes at least one of a semiconductor device, an integrated circuit chip, and a computer. A seamless conductive mesh is formed on at least one surface of the electronic device. The conductive mesh is in electrical contact with the terminal. The terminal facilitates electrical conduction between the conductive mesh and an electrical detection circuit. The electronic device also may include a pattern having traces formed on at least two surfaces where each of the traces includes a continuous loop of conductive material is formed on at least two surfaces. The electronic device also may include a first plurality of conductive loops formed on the electronic device that are continuous and surround the electronic device in a first direction and a second plurality of conductive loops formed on the electronic device that are continuous and surround the electronic device in a second direction.

Anti-tamper mesh

A method of fabricating an electronic circuit including forming a first depression on a first surface of a first wafer and forming a second depression on the first surface of the first wafer. The second depression is adjacent the first depression and separated from the first depression by a wall. The method further includes locating an actuator on the wall and attaching a first surface of a second wafer to the first surface of the first wafer to cover the first and second depressions. A first portion of the second wafer and the first depression define a first reservoir to contain a first chemical, and a second portion of the second wafer and the second depression define a second reservoir to contain a second chemical.

Destructor integrated circuit chip, interposer electronic device and methods

A method including positioning an electronic device proximate a second device, the electronic device including at least one of a semiconductor device, an integrated circuit chip, and an electronic substrate, and the second device activatable to form a conductive pattern on the electronic device. The method further includes activating the second device to form the conductive pattern and forming the conductive pattern on at least two surfaces of the electronic device. The conductive pattern includes one or more than one conductive trace. Each conductive trace includes a conductive material and is continuous between at least two surfaces of the electronic device. Each conductive trace is formed by controlling relative movement of the electronic device and the second device during activation of the second device.

Method for forming an anti-tamper mesh

A method of forming an anti-tamper mesh on an electronic device. The method includes forming at least one terminal on the electronic device and forming a conductive mesh on at least one surface of the electronic device, wherein the conductive mesh is in electrical contact with the terminal, and wherein the terminal facilitates electrical conduction between the conductive mesh and an electrical detection circuit.

A semiconductor device. The device includes a substrate and an integrated circuit chip. The device also includes an electrically or thermally reactive layer located between a top surface of the substrate and a bottom surface of the integrated circuit chip, wherein the reactive layer is positioned such that detection of tampering causes the reactive layer to be electrically or thermally energized such that the semiconductor device is at least partially destroyed.

A semiconductor chip includes a first integrated circuit chip and a depression substrate attached to the integrated circuit chip, wherein the integrated circuit chip and the depression substrate define a cavity therebetween. The semiconductor chip also includes a stress sensitive material located in the cavity and a chemical located in the cavity, wherein detection of tampering causes a reaction by the chemical such that the semiconductor chip is at least partially destroyed.
