A method of etching a metal oxide layer formed on a metal layer is provided. The method includes mounting a specimen having the metal oxide layer and a photoresist on the metal oxide layer in a reaction chamber, wherein the metal oxide layer is formed on the metal layer and a pattern is formed on the photoresist. Primary etching of the metal oxide layer exposed by the photoresist may be performed using Cl2 gas in an inductively coupled plasma method. Secondary etching of residues remaining on an etched region of the metal oxide layer may be performed using BCl3 gas in the inductively coupled plasma method.

An etching method of a nickel oxide layer and a method of manufacturing a storage node of a resistive memory including the nickel oxide layer are provided. The method of etching the nickel oxide layer includes forming a nickel oxide layer on a substrate, forming a mask pattern on a desired region of the nickel oxide layer, removing the nickel oxide layer around the mask pattern using plasma generated from a mixed etching gas having a desired ratio of a main gas and an additive gas and removing the mask pattern.

Provided is a method of manufacturing a nano-sized MTJ cell in which a contact in the MTJ cell is formed without forming a contact hole. The method of forming the MTJ cell includes forming an MTJ layer on a substrate, forming an MTJ cell region by patterning the MTJ layer, sequentially depositing an insulating layer and a mask layer on the MTJ layer, exposing an upper surface of the MTJ cell region by etching the mask layer and the insulating layer at the same etching rate, and depositing a metal layer on the insulating layer and the MTJ layer.
