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).

1. A tamper-proof electronic package comprising: a glass substrate, the glass substrate comprising stressed glass with a compressively-stressed surface layer;at least one electronic component secured to the glass substrate within a secure volume of the tamper-proof electronic package, the at least one electronic component comprising an electronic module;an enclosure defining, at least in part, the secure volume;a tamper-respondent detector monitoring for the attempted intrusion event into the secure volume;a fragmenting trigger element secured to the glass substrate to trigger fragmentation of the glass substrate with the tamper-respondent detector detecting the attempted intrusion event into the secure volume;wherein the enclosure comprises a plurality of stressed glass elements adhesively bonded together to form the enclosure, each stressed glass element comprising a respective, compressively-stressed surface layer, and the plurality of stressed glass elements defining multiple sides of the secure volume, and wherein one stressed glass element of the plurality of stressed glass elements comprises the glass substrate, and the at least one electronic component and the fragmentation trigger element are adhesively secured to the one stressed glass element andwherein the glass substrate fragments with an attempted intrusion event into the tamper-proof electronic package, the fragmenting of the glass substrate also fragmenting the at least one electronic component secured thereto, destroying the at least one electronic component. 2. The tamper-proof electronic package of claim 1, wherein the glass substrate has undergone ion-exchange processing to provide the stressed glass with the compressively-stressed surface layer. 3. The tamper-proof electronic package of claim 1, wherein the compressively-stressed surface layer of the stressed glass is compressively stressed to ensure that the stressed glass fragments into glass particles of fragmentation size less than 1000 μms with the attempted intrusion event. 4. The tamper-proof electronic package of claim 1, wherein the at least one electronic component comprises at least one memory component, the at least one memory component comprising persistent memory adhesively secured to the glass substrate. 5. The tamper-proof electronic package of claim 1, wherein the enclosure is a glass enclosure defining, at least in part, the secure volume, the glass enclosure comprising stressed glass with a compressively-stressed surface layer. 6. A fabrication method comprising: fabricating a tamper-proof electronic package, the fabricating comprising: providing a glass substrate, the glass substrate comprising stressed glass with a compressively-stressed surface layer;securing at least one electronic component to the glass substrate, and the glass substrate being within a secure volume of the tamper-proof electronic package, and the at least one electronic component comprising an electronic module;providing an enclosure defining, at least in part, the secure volume;providing a tamper-respondent detector monitoring for the attempted intrusion event into the secure volume;providing a fragmenting trigger element secured to the glass substrate to trigger fragmentation of the glass substrate with the tamper-responding detector detecting the attempted intrusion event into the secure volume;wherein the enclosure comprises a plurality of stressed glass elements adhesively bonded together to form the enclosure, each stressed glass element comprising a respective, compressively-stressed surface layer, and the plurality of stressed glass elements defining multiple sides of the secure volume, and wherein one stressed glass element of the plurality of stressed glass elements comprises the glass substrate, and the at least one electronic component and the fragmentation trigger element are adhesively secured to the one stressed glass element; andwherein the glass substrate fragments with an attempted intrusion event into the secure volume of the tamper-proof electronic package, the fragmenting of the glass substrate also fragmenting the at least one electronic component secured thereto, destroying the at least one electronic component. 7. The method of claim 6, wherein providing the glass substrate comprises machining the glass substrate to a desired configuration, and then ion-exchange processing the glass substrate to obtain the stressed glass with the compressively-stressed surface layer, and wherein the at least one electronic component comprises at least one memory component, the at least one memory component comprising persistent memory, and the method comprises adhesively securing the persistent memory to the glass substrate.
