Patent ID: 11942553
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A method for fabricating a semiconductor device, the method comprising:
forming an insulating buffer film;
sequentially forming a liner film and a metal oxide film on the insulating buffer film;
crystallizing the metal oxide film through an annealing process;
forming a liner pattern and a crystallized metal oxide pattern on the insulating buffer film by patterning the crystallized metal oxide film and the liner film;
forming an insulating film extending along a sidewall of the liner pattern, a sidewall of the crystallized metal oxide pattern, and an upper surface of the crystallized metal oxide pattern; and
forming a gate electrode on the insulating film,
wherein the liner pattern includes a transition metal oxide or a transition metal oxynitride.
