摘要:
Complex mixed metal containing thin films can be deposited by CVD from liquid mixtures of metal complexes without solvent by direct liquid injection and by other precursor dispersing method such as aerosol delivery with subsequent annealing to improve electrical properties of the deposited films. This process has potential for commercial success in microelectronics device fabrication of dielectrics, ferroelectrics, barrier metals/electrodes, superconductors, catalysts, and protective coatings. Application of this process, particularly the CVD of ZrSnTiOx (zirconium tin titanate, or ZTT) and HfSnTiOx (hafnium tin titanate, or HTT) thin films has been studied successfully.
摘要:
The present invention is a composition for deposition of a mixed metal or metal compound layer, comprising a solventless mixture of at least two metal-ligand complex precursors, wherein the mixture is liquid at ambient conditions and the ligands are the same and are selected from the group consisting of alkyls, alkoxides, halides, hydrides, amides, imides, azides cyclopentadienyls, carbonyls, and their fluorine, oxygen and nitrogen substituted analogs. The present invention is also a process for deposition of a multiple metal or metal compound layer on a substrate of an electronic material, comprising: a) providing a solventless mixture of two or more metal-ligand complex precursors which constitute a liquid at ambient conditions, wherein the ligands are the same and are selected from the group consisting of alkyls, alkoxides, halides, hydrides, amides, imides, azides, nitrates, cyclopentadienyls, carbonyls, pyrazoles, and their fluorine, oxygen and nitrogen substituted analogs; b) delivering the solventless mixture by direct liquid injection to a flash vaporization zone to vaporize the solventless mixture; c) contacting the substrate under deposition conditions with a resulting vapor of the solventless mixture, and c) depositing a multiple metal or metal compound layer on the substrate from the solventless mixture.

A process for deposition of a multiple metal and metalloid compound layer with a compositional gradient of the metal and metalloid in the layer on a substrate of an electronic material, comprising: a) providing two or more metal-ligand and metalloid-ligand complex precursors, wherein the ligands are preferably the same; b) delivering the precursors to a deposition zone where the substrate is located; c) contacting the substrate under deposition conditions with the precursors; d) varying the temperature of deposition from a first temperature to a second distinct temperature which is at least 40° C. from said first temperature during the contact, and e) depositing a multiple metal and metalloid compound layer on the substrate from the precursors resulting in the compositional gradient of the metal and metalloid in the layer as a result of step d). An oxygen source can be added to result in a metal-metalloid oxide, or a nitrogen source can be added to result in a metal-metalloid nitride, or a mixture of an oxygen and a nitrogen source can be added to result in a metal-metalloid oxynitride. The metalloid would preferably be silicon.
