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

Claim 12:
13. A method for fabricating a semiconductor device, the method comprising:
sequentially forming a transition metal film and a metal oxide film on a substrate, the transition metal film being in contact with the metal oxide film;
forming a transition metal pattern and a metal oxide pattern on the substrate by patterning the transition metal film and the metal oxide film;
crystallizing the metal oxide pattern through performing an annealing process in an oxygen atmosphere;
forming a gate insulating film extending along a sidewall of the transition metal pattern, a sidewall of the crystallized metal oxide pattern, and an upper surface of the crystallized metal oxide pattern;
forming a gate electrode on the gate insulating film; and
forming a contact on both sides of the gate electrode, wherein the contact penetrates through the gate insulating film to be connected to the crystallized metal oxide pattern.
