Abstract:
A method is provided for forming a stack of film layers for use in 3D memory devices. The method starts with providing a substrate in a processing chamber of a deposition reactor. Then one or more process gases suitable for forming a dielectric layer are supplied into the processing chamber of the deposition reactor forming a dielectric layer on the substrate. Then one or more process gases suitable for forming a metallic layer are supplied into the processing chamber of the deposition reactor forming a metallic layer on the dielectric layer. Then one or more process gases suitable for forming a metallic nitride adhesion layer are supplied into the processing chamber of the deposition reactor forming a metallic nitride adhesion layer on the metallic layer. The sequence is then repeated to form a desired number of layers.
