Patent ID: 7659215

Claim:
A method for depositing a nanolaminate film for non-volatile floating gate memory devices, the method comprising the steps of: a) introducing a substrate into an atomic layer deposition reactor; b) forming on the substrate a first high-dielectric-constant layer by alternately supplying an oxygen source and a metal source selected from among an aluminum source, a zirconium source and a hafnium source; c) forming on the first high-dielectric-constant layer a nickel oxide layer by alternately supplying a nickel source and an oxygen source wherein the nickel source is one compound selected from the group consisting of nickel chloride (NiCl 2 ), Ni(acac) 2 (acac=acetylacetonato), Ni(tmhd) 2 (tmhd=2,2,6,6-tetramethyl-3,5-heptanedioato), Ni(dmg) 2 (dmg=dimethylglyoximato), Ni(apo) 2 (apo=2-amino-Dent-2-en-4-onato) and nickel aminoalkoxide, represented by Formula 1 [Formula 1] wherein m is an integer ranging from 1 to 3, and R and R′, which may be the same or different, represent a linear or branched-chain C 1 -C 4 alkyl group; and d) forming on the nickel oxide layer a second high-dielectric-constant layer by alternately supplying an oxygen source and a metal source selected from among an aluminum source, a zirconium source and a hafnium source.
