A transient electronic device utilizes a glass-based interposer that is treated using ion-exchange processing to increase its fragility, and includes a trigger device operably mounted on a surface thereof. An integrated circuit (IC) die is then bonded to the interposer, and the interposer is mounted to a package structure where it serves, under normal operating conditions, to operably connect the IC die to the package I/O pins/balls. During a transient event (e.g., when unauthorized tampering is detected), a trigger signal is transmitted to the trigger device, causing the trigger device to generate an initial fracture force that is applied onto the glass-based interposer substrate. The interposer is configured such that the initial fracture force propagates through the glass-based interposer substrate with sufficient energy to both entirely powderize the interposer, and to transfer to the IC die, whereby the IC die also powderizes (i.e., visually disappears).

In an embodiment, an integrated circuit includes a clock tree circuit and logic circuitry that is clocked by the clocks received from the clock tree circuit. The logic circuit is powered by a first power supply voltage. The integrated circuit includes a voltage regulator that receives the first power supply voltage and generates a second power supply voltage having a magnitude that is lower than the magnitude of the first power supply voltage by a predetermined amount. The second power supply voltage may track the first power supply voltage over dynamic changes during use, either intentional changes to operating state or noise-induced changes. The second power supply voltage may be used to power at least a portion of the clock tree.
