    摘要： A first multilayer body is formed by alternately layering dielectric films and electrode films on a substrate. Then, an end portion of the first multilayer body is processed into a staircase shape, and a first interlayer dielectric film is formed around the first multilayer body. Next, a plurality of contact holes having a diameter decreasing downward are formed in the first interlayer dielectric film so that the contact holes reach respective end portions of the electrode films. Then, a sacrificial material is buried in the contact holes. Next, a second multilayer body is formed immediately above the first multilayer body, and a second interlayer dielectric film is formed around the second multilayer body. Thereafter, a plurality of contact holes having a diameter decreasing downward are formed in the second interlayer dielectric film to communicate with the respective contact holes formed in the first interlayer dielectric film. Then, the sacrificial material is removed and a contact is buried inside the contact holes. The contact has a step difference.
