Abstract:
1. A semiconductor structure, comprising: a first substrate; a semiconductor device on the first substrate, a second substrate; a conductive bond between the first substrate and the second substrate that surrounds the semiconductor device to seal the semiconductor device between the first substrate and the second substrate, wherein: a multilayer stack located between the first substrate and the second substrate and formed on one of the first substrate or the second substrate, the multilayer stack includes a first layer comprising silicon, a second layer comprising polycrystalline silicon germanium, and a third layer comprising polycrystalline germanium, wherein the first layer is located closest to the one of the first substrate or the second substrate, the third layer is located furthest from the one of the first substrate or the second substrate, and the second layer is located between the first layer and the third layer; wherein the conductive bond includes material formed from material of the first layer, material of the second layer, and material the third layer.
