Claim 17:
18. The semiconductor device of claim 17, wherein,
the second sub-semiconductor structure further comprises a second bonding layer, and the second bonding layer is disposed on a side of the carrier substrate close to the first sub-semiconductor structure, the first portion of the first bonding layer is bonded to a first portion of the second bonding layer, and the cavity is defined between the second portion of the first bonding layer and a second portion of the second bonding layer, or
the first portion of the first bonding layer is bonded to a first portion of the carrier substrate, and the cavity is defined between the second portion of the first bonding layer and a second portion of the carrier substrate, or
the second sub-semiconductor structure further comprises a barrier layer, and the barrier layer is disposed on a side of the carrier substrate close to the first sub-semiconductor structure, the first portion of the first bonding layer is bonded to a first portion of the barrier layer, and the cavity is defined between the second portion of the first bonding layer and a second portion of the barrier layer, or
the second sub-semiconductor structure further comprises a barrier layer and a buffer layer, the barrier layer and the buffer layer are disposed on a side of the carrier substrate close to the first sub-semiconductor structure, the first portion of the first bonding layer is bonded to a first portion of the buffer layer, and the cavity is defined between the second portion of the first bonding layer and a second portion of the buffer layer.
