Patent ID: 8330221

Claim:
A semiconductor substrate comprising: a base substrate having an insulating surface; a first bonding layer over a first region of the base substrate; a first silicon nitride oxide layer over the first bonding layer; a first silicon oxynitride layer over the first silicon nitride oxide layer; a first single-crystalline semiconductor layer over the first silicon oxynitride layer; a second bonding layer over a second region of the base substrate adjacent to the first region of the base substrate; a second silicon nitride oxide layer over the second bonding layer; a second silicon oxynitride layer over the second silicon nitride oxide layer; a second single-crystalline semiconductor layer over the second silicon oxynitride layer, wherein a side surface of the first bonding layer and a side surface of the second bonding layer are in direct contact with each other, so as to form a first interface between the first bonding layer and the second bonding layer, wherein a side surface of the first single-crystalline semiconductor layer and a side surface of the second single-crystalline semiconductor layer are in direct contact with each other, so as to form a second interface between the first single-crystalline semiconductor layer and the second single-crystalline semiconductor layer.
