Abstract:
In one aspect, the invention is formulations comprising both organoaminohafnium and organoaminosilane precursor compounds that allows anchoring both silicon-containing fragments and hafnium-containing fragments onto a given surface having hydroxyl groups to deposit silicon doped hafnium oxide having a silicon doping level ranging from 0.5 to 8 mol %, suitable as ferroelectric material. In another aspect, the invention is methods and systems for depositing the silicon doped hafnium oxide films as ferroelectric materials using the formulations.

Claim (Index 7):
A method to deposit a film comprising silicon, hafnium and oxygen onto a substrate, comprising:\n a) providing the substrate in a reactor; b) introducing into the reactor a composition comprising:\n (i) at least one organoaminosilane precursor compound having a formula of\n R x Si(NR 1 R 2 ) 4-x ; \n wherein \n R is halide selected from the group consisting of Cl, Br, and I; \n R 1  and R 2  are independently selected from linear or branched C 1  to C 6  alkyl in organoamino group;\n wherein R 1  and R 2  are linked to form a cyclic ring structure; or R 1  and R 2  are not linked to form a cyclic ring structure; and \n \n x=0, 1, or 2; \n and \n \n (ii) at least one organoaminohafnium precursor compound having a formula of\n L x Hf(NR 1 R 2 ) 4-x ; \n wherein \n L is cyclopentadienyl or alkyl substituted cyclopentadienyl; \n R 1  and R 2  are independently selected from linear or branched C 1  to C 6  alkyl in organoamino group; wherein\n R 1  and R 2  are linked to form a cyclic ring structure or R 1  and R 2  are not linked to form a cyclic ring structure; and \n \n x=0, 1, or 2; \n \n c) purging the reactor with a purge gas; \n d) introducing an oxygen-containing source into the reactor; and \n e) purging the reactor with the purge gas; \n wherein \n melting point of the composition is \u226430\u00b0 C.; \n the oxygen-containing source is selected from the group consisting of an oxygen plasma, ozone, a water vapor, water vapor plasma, nitrogen oxide plasma, a carbon oxide plasma, and combinations thereof; \n the purge gas selected from the group consisting of argon (Ar), nitrogen (N 2 ), helium (He), neon, hydrogen (H 2 ), and combinations thereof; \n deposition process is selected from the group consisting of a thermal atomic layer deposition (ALD), plasma enhanced atomic layer deposition (PEALD) process, cyclic chemical vapor deposition, plasma enhanced cyclic chemical vapor deposition, and combination thereof; \n the method is conducted at a temperature ranging from 100\u00b0 C. to 600\u00b0 C.; and \n b) through e) are repeated until a desired thickness of film is deposited.
