Abstract

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).
