The substrate has a concave portion extending along a first direction into the substrate from a surface thereof. The multi-layers stack includes a plurality of conductive layers and a plurality of insulating layers alternatively stacked along the first direction on a bottom of the concave portion. The multi-layers stack also has at least one recess passing through the conductive layers and the insulating layers along the first direction, wherein the recess has a cross-sectional bottom profile and a cross-sectional opening profile perpendicular to the first direction and the cross-sectional bottom profile has a size substantially greater than that of the cross-sectional opening profile. The dielectric material is at least partially filled in the recess."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three dimensional memory device and method for fabricating the same","description":"A 3D memory device includes a substrate, a multi-layers stack and a dielectric material.
