Tamper-proof electronic packages and fabrication methods are provided which include a glass enclosure enclosing, at least in part, at least one electronic component within a secure volume, and a tamper-respondent detector. The glass enclosure includes stressed glass with a compressively-stressed surface layer, and the tamper-respondent detector monitors, at least in part, the stressed glass to facilitate defining the secure volume. The stressed glass fragments with an attempted intrusion event through the stressed glass, and the tamper-respondent detector detects the fragmenting of the stressed glass. In certain embodiments, the stressed glass may be a machined glass enclosure that has undergone ion-exchange processing, and the compressively-stressed surface layer of the stressed glass may be compressively-stressed to ensure that the stressed glass fragments into glass particles of fragmentation size less than 1000 μm with the intrusion event.

Tamper-proof electronic packages and fabrication methods are provided which include a glass substrate. The glass substrate is stressed glass with a compressively-stressed surface layer. Further, one or more electronic components are secured to the glass substrate within a secure volume of the tamper-proof electronic package. In operation, the glass substrate is configured to fragment with an attempted intrusion event into the electronic package, and the fragmenting of the glass substrate also fragments the electronic component(s) secured to the glass substrate, thereby destroying the electronic component(s). In certain implementations, the glass substrate has undergone ion-exchange processing to provide the stressed glass. Further, the electronic package may include an enclosure, and the glass substrate may be located within the secure volume separate from the enclosure, or alternatively, the enclosure may be a stressed glass enclosure, an inner surface of which is the glass substrate for the electronic component(s).
