Classification: CPC H | IPC H

Claim 0:
1. A method for fabricating a semiconductor device, the method comprising:
sequentially forming a liner film and a metal oxide film on a substrate, the liner film including a transition metal and being in contact with the metal oxide film;
crystallizing the metal oxide film through an annealing process;
forming a liner pattern and a metal oxide pattern on the substrate by patterning the liner film and the metal oxide film;
forming an insulating film extending along a sidewall of the liner pattern, a sidewall of the metal oxide pattern, and an upper surface of the metal oxide pattern; and
forming a gate electrode on the insulating film,
wherein the annealing process is performed in a nitrogen atmosphere or an oxygen atmosphere.
