Patent ID: 8896102

Claim:
A die structure comprising: a diced portion of a semiconductor substrate including a first layer of semiconductor material, a buried layer of dielectric material, and a handle layer of semiconductor material, the buried layer overlying the handle layer and the first layer overlying the buried layer, the diced portion including a device region of the first layer, the device region having one or more semiconductor devices fabricated thereon; a sealing structure within the first layer of the semiconductor substrate and the buried layer of dielectric material, the sealing structure contacting the handle layer and circumscribing the device region; and a crackstop structure circumscribing the device region, the crackstop structure overlying the sealing structure, wherein the crackstop structure and the sealing structure cooperate to electrically connect the handle layer to the first layer to provide a voltage of the handle layer as a reference voltage for the device region.
