Abstract
Disclosed is a multilayer insulator, a metal-insulator-metal (MIM) capacitor with the same, and a fabricating method thereof. The capacitor includes: a first electrode; an insulator disposed on the first electrode, the insulator including: a laminate structure in which an aluminum oxide (AlO) layer and a hafnium oxide (HfO) layer are laminated alternately in an iterative manner and a bottom layer and a top layer are formed of the same material; and a second electrode disposed on the insulator.
