Abstract:
A method for manufacturing a zirconium oxide film for use in a semiconductor device by using an atomic layer deposition (ALD), the method comprising steps of:a) setting a wafer in a reaction chamber; b) supplying a zirconium source material of Zr(OC(CH3)3)4 (zirconium tetra-tert-butoxide) into the reaction chamber; c) purging out unreacted Zr(OC(CH3)3)4; d) supplying an oxygen source material into the reaction chamber; e) purging out unreacted oxygen source material; and f) carrying out a process using an oxygen gas plasma selected from the group consisting of UVâ€”O3, N2O, O2 and O3.
