摘要： A novel lead zirconium titanate (PZT) material having unique properties and application for PZT thin film capacitors and ferroelectric capacitor structures, e.g., FeRAMs, employing such thin film material. The PZT material is scalable, being dimensionally scalable, pulse length scalable and/or E-field scalable in character, and is useful for ferroelectric capacitors over a wide range of thicknesses, e.g., from about 20 nanometers to about 150 nanometers, and a range of lateral dimensions extending to as low as 0.15 μm. Corresponding capacitor areas (i.e., lateral scaling) in a preferred embodiment are in the range of from about 104 to about 10−2 μm2. The scalable PZT material of the invention may be formed by liquid delivery MOCVD, without PZT film modification techniques such as acceptor doping or use of film modifiers (e.g., Nb, Ta, La, Sr, Ca and the like).

摘要： A method of preventing oxygen deficiency in a ferroelectric or high ε film material having a top electrode layer deposited thereon. Process conditions are employed that either enable the top electrode layer to be formed without oxygen abstraction from the ferroelectric or high ε film material in the vicinity and at the top surface thereof, or else provide the ferroelectric or high ε film material in the vicinity and at the top surface thereof with a surplus of oxygen. In the latter case, the deposition formation of the top electrode layer on the ferroelectric or high ε film material depletes the over-stoichiometric excess of the oxygen in the film material, to yield a device structure including an electrode on a film material having a proper stoichiometry, e.g., of PbZrTiO3.

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.
