摘要:
A semiconductor structure includes a glass substrate and a device wafer. The glass substrate includes a glass layer, a heat dissipation layer and a silicon nitride layer stacked from bottom to top. The device wafer includes at least one semiconductor device integrated in a device layer situated over the silicon nitride layer of the glass substrate. Or, the glass substrate includes a glass layer and a silicon nitride layer stacked from bottom to top. The device wafer includes at least one semiconductor device integrated in a device layer, and a heat dissipation layer is stacked on the device layer, wherein the heat dissipation layer is bonded with the silicon nitride layer of the glass substrate. The present invention also provides a method of wafer bonding for manufacturing said semiconductor structure.
