Abstract
Three-dimensional (3D) memory devices and fabricating methods thereof are disclosed. In certain aspects, a disclosed 3D memory device can comprise a first semiconductor structure including a core region, a staircase region, and a periphery region, and a second semiconductor structure including a second periphery circuit on a substrate. The first semiconductor structure can include a memory stack on an activated semiconductor layer in the core region, a staircase structure on a supplemental semiconductor layer in the staircase region, and a first periphery circuit on a doped semiconductor film in the periphery region. The second semiconductor structure is connected with the first semiconductor structure.
