A new alkoxide precursor, Hf(mp) 4 [mp = 3-methyl-3-pentoxide, OC(CH 3 )(C 2 H 5 ) 2 ] has been employed in the atomic layer deposition (ALD) of HfO 2 thin films using water (H 2 O) as the oxygen source. The self-limiting ALD process via alternate surface reactions of Hf(mp) 4 and H 2 O is confirmed
Yttrium oxide thin film deposition by atomic layer epitaxy (ALE) was studied at 200±425 C using Y(thd) 3 , Y(thd) 3 (bipyridyl), or Y(thd) 3 (1,10-phenanthroline) (thd = 2,2,6,6-tetramethyl-3,5-heptanedione) as an yttrium precursor, and ozone as an oxygen source. All yttrium precursors were analyzed
