Abstract:
A method of fabricating a semiconductor device is described. A plurality of first films and a plurality of second films are alternately formed on a substrate. A hole is formed in the first and second films. A first metal layer is formed on a surface of the hole. The first metal layer is removed from a bottom surface of the hole. A second metal layer may be formed on a surface of the first metal layer after removing the first metal layer from the bottom surface of the hole. The bottom of the hole exposed from the first and second metal layers may be processed to increase a depth of the hole.

Claim (Index 15):
A semiconductor device comprising:\n a plurality of first films and a plurality of second films alternately provided on a substrate; and a conductor layer or a semiconductor layer provided in the first and second films, wherein the first and second films have a side surface which has a tubular shape and surrounds the conductor layer or the semiconductor layer, the side surface of the first and second films comprises:\n a first side surface having a tubular shape, and \n a second side surface that is located below the first side surface and has a tubular shape, and \n an inflection point disposed between the first side surface and the second side surface, a diameter of a bottom of the second side surface is smaller than a diameter of the inflection point.
