Abstract
A semiconductor device includes an underlying substrate, two stack units disposed over the underlying substrate, and a feature disposed between the stack units. The stack units are spaced apart from each other. Each of the stack units includes a plurality of conductive films and a plurality of dielectric films disposed to alternate with the conductive films, an inter-metal dielectric (IMD) portion, and a hard mask film. An uppermost one of the dielectric films of each of the stack units is disposed over the conductive films, and has a dimension smaller than those of the conductive films and those of remaining ones of the dielectric films of each of the stack units. The feature includes a plurality of repeating units and a plurality of separators which are disposed to alternate with the repeating units. A method for manufacturing the semiconductor device is also disclosed.
