    摘要: A modified PbZrTiO3 perovskite crystal material thin film, wherein the PbZrTiO3 perovskite crystal material includes crystal lattice A-sites and B-sites at least one of which is modified by the presence of a substituent selected from the group consisting of (i) A-site substituents consisting of Sr, Ca, Ba and Mg, and (ii) B-site substituents selected from the group consisting of Nb and Ta. The perovskite crystal thin film material may be formed by liquid delivery MOCVD from metalorganic precursors of the metal components of the thin film, to form PZT and PSZT, and other piezoelectric and ferroelectric thin film materials. The thin films of the invention have utility in non-volatile ferroelectric memory devices (NV-FeRAMs), and in microelectromechanical systems (MEMS) as sensor and/or actuator elements, e.g., high speed digital system actuators requiring low input power levels.

    摘要: An ultra low k dielectric film, including a silicon film containing porosity deriving from a porogen, as formed from a precursor silane and a porogen, wherein the precursor silane has a water content below 10 ppm, based on total weight of the precursor silane, and/or the porogen has a water content below 10 ppm, based on total weight of the porogen. In one implementation, the precursor silane is diethoxymethylsilane, and the porogen is bicyclo[2.2.1]-hepta-2,5-diene having a trace water content below 10 ppm, based on total weight of said bicyclo[2.2.1]-hepta-2,5-diene. These super-dry reagents are unexpectedly polymerization-resistant during their delivery and deposition in the formation of ultra low k films, and are advantageously employed to produce ultra low k films of superior character.

    摘要: A liquid delivery MOCVD method for deposition of dielectric materials such as (Ba,Sr) titanates and (Zr,Sn) titanates, in which metal source compounds are dissolved or suspended in solvent and flash vaporized at temperatures of from about 100° C. to about 300° C. and carried via a carrier gas such as argon, nitrogen, helium, ammonia or the like, into a chemical vapor deposition reactor wherein the precursor vapor is mixed with an oxidizing co-reactant gas such as oxygen, ozone, N2O, etc., to deposit the high dielectric metal oxide film on the substrate at a temperature of from about 400° C. to about 1200° C. at a chemical vapor deposition chamber pressure of from about 0.1 torr to about 760 torr. Such process may for example be employed to form a (Ba,Sr) titanate dielectric material wherein at least 60 atomic % of the total metal content of the oxide is titanium. The high dielectric material of the invention may be used to form capacitive microelectronic device structures for applications such as dynamic random access memories and high frequency capacitors.
