Abstract: Compositions and methods of using said composition for removing polymeric materials from surfaces, preferably cleaning contaminant buildup from a lithography apparatus without total disassembly of said apparatus.

Abstract: Methods of reducing the capillary forces experienced by fragile high aspect ratio structures during drying to substantially prevent damage to said high aspect ratio structures during drying. They include modifying the surface of the high aspect ratio structures such that the forces are sufficiently minimized and as such less than 10% of the high aspect ratio features will have bent or collapsed during drying of the structure having said features thereon.

Abstract: 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 ?m. Corresponding capacitor areas (i.e., lateral scaling) in a preferred embodiment are in the range of from about 104 to about 10?2 ?m. 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).

Abstract: An organosilicon precursor for vapor deposition, e.g., low pressure (<100 Torr), plasma-enhanced chemical vapor deposition (PECVD) of a low k, high strength dielectric film, wherein the precursor includes at least one of: (i) silicon-pendant oxiranyl functionality; and (ii) a disilyl moiety of the formula wherein x is an integer having a value of from 0 to 4 inclusive. These precursors are useful for the formation of dielectric films having dielectric constants on the order of ˜3 and less, and a hardness exceeding ˜1 GigaPascals.
