The method can comprise forming a device wafer including: forming a first channel hole penetrating a first alternating layer stack of a device wafer, forming an epitaxial layer on a bottom of the first channel hole, and forming a first channel layer on a sidewall of the first channel hole. The method can further comprise forming at least one connecting wafer, each connecting wafer including a second channel hole penetrating a second alternating layer stack without an epitaxial layer on a bottom of the second channel hole; and bonding the at least one connecting wafer and the device wafer, such that a second channel layer on a sidewall of the second channel hole in each connecting wafer is electrically connected with the first channel layer in the device wafer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for forming a three-dimensional memory device","description":"Embodiments of a method for forming a three-dimensional (3D) memory devices are disclosed.
