Bonded three-dimensional memory devices and methods for forming the same
Embodiments of bonded 3D memory devices and fabrication methods thereof are disclosed. In an example, a 3D memory device includes a first semiconductor structure and a second semiconductor structure. The first semiconductor structure includes a first memory stack having a plurality of first conductor layers and a first bonding layer having a plurality of first word line bonding contacts conductively connected to the plurality of first conductor layers, respectively. A second semiconductor structure includes a second memory stack having a plurality of second conductor layers and a second bonding layer having a plurality of second word line bonding contacts conductively connected to the plurality of second conductor layers, respectively. The 3D memory device also includes a bonding interface between the first bonding layer and the second bonding layer, at which the first word line bonding contacts are in contact with the second word line bonding contacts.
