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 (Al 2 O 3 ) layer and a hafnium oxide (HfO 2 ) 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.

Claim (Index 12):
A method for fabricating a semiconductor device, comprising:\n forming a first electrode; forming an insulator having a laminate structure in which two or more first dielectric layers and two or more second dielectric layers are laminated alternately in an iterative manner, and having a bottom layer and a top layer; forming a second electrode on the insulator, wherein an upper surface of the bottom layer has a greater surface area than an upper surface of the top layer such that a portion of the bottom layer extends outside the top layer; an upper surface of at least one layer of the two or more first dielectric layers and the two or more second dielectric layers have a substantially equal surface area as the upper surface of the top layer; and an upper surface of at least one other layer of the two or more first dielectric layers and the two or more second dielectric layers have a substantially equal surface area as the upper surface of the bottom layer, such that a portion of the laminate structure disposed on the bottom layer outside the top layer has a thickness that is less than a portion of the laminate structure covered with the top layer.
