Abstract:
Chemical vapor deposition is used to form a film of Bi oxide, Sr oxide, and Ta oxide on a heated substrate by decomposing the precursors of these oxides at the surface of the substrate. The precursor of Bi oxide is a Bi complex which includes at least one alcoxide group and is decomposed and deposited at a temperature lower than 450 DEG C. The film of Bi, Sr, and Ta oxides obtained by low-temperature CVD is predominantly non-ferroelectric, but can be converted into a ferroelectric film by a subsequent heating process.
Abstract:
A system and method for forming a phase change memory material on a substrate, in which the substrate is contacted with precursors for a phase change memory chalcogenide alloy under conditions producing deposition of the chalcogenide alloy on the substrate, at temperature below 350°C, with the contacting being carried out via chemical vapor deposition or atomic layer deposition. Various tellurium, germanium and germanium-tellurium precursors are described, which are useful for forming GST phase change memory films on substrates.
Abstract:
A low temperature CVD process for deposition of bismuth-containing ceramic thin films (12) suitable for integration to fabricate ferroelectric memory devices (10). The bismuth-containing film can be formed using a tris ( beta -diketonate) bismuth precursor. Films of amorphous SBT can be formed by CVD and then ferroannealed to produce films with Aurivillius phase composition having superior ferroelectric properties suitable for manufacturing high density FRAMs.
Abstract:
Apparatus and method for volatilizing a source reagent susceptible to particle generation or presence of particles in the corresponding source reagent vapor, in which such particle generation or presence is suppressed by structural or processing features of the vapor generation system. Such apparatus and method are applicable to liquid and solid source reagents, particularly solid source reagents such as metal halides, e.g., hafnium chloride. The source reagent in one specific implementation is constituted by a porous monolithic bulk form of the source reagent material. The apparatus and method of the invention are usefully employed to provide source reagent vapor for applications such as atomic layer deposition (ALD) and ion implantation.
Abstract:
A CVD Method of forming gate dielectric thin films on a substrate using metalloamide compounds of the formula M(NR1R2)x, or (I), wherein M is Zr, Hf, Z, La, Lanthanide series elements, Ta, Ti, or Al; N is nitrogen; each of R?1 and R2¿ is same or different and is independently selected from H, aryl, perfluoraryl, C¿1?-C8 alkyl, C1-C8 perfluoroalkyl, alkylsilyl; and x is the oxidation state on metal M; and an aminosilane compound of the formula HxSiAy(NR?1R2)¿4-x-y or (II), wherein H is hydrogen; x is from 0 to 3; Si is silicon; A is a halogen; Y is from 0 to 3; N is nitrogen; each of R?1 and R2¿ is same or different and is independently selected from the group consisting of H, aryl, perfluoroaryl, C¿1?-c8 alkyl, and C1-C8 perfluoroalkyl; and n is from 1-6. By comparison with the standard SiO2 gate dielectric materials, these gate dielectric materials provide low levels of carbon and halide impurity.
