Barium, strontium, tantalum and lanthanum precursor compositions useful for atomic layer deposition (ALD) and chemical vapor deposition (CVD) of titanate thin films. The precursors have the formula M(Cp)2, wherein M is strontium, barium, tantalum or lanthanum, and Cp is cyclopentadienyl, of the formula (I), wherein each of R1-R5 is the same as or different from one another, with each being independently selected from among hydrogen, C1-C12 alkyl, C1-C12 amino, C6-C10 aryl, C1-C12 alkoxy, C3-C6 alkylsilyl, C2-C12 alkenyl, R1R2R3NNR3, wherein R1, R2 and R3 may be the same as or different from one another and each is independently selected from hydrogen and C1-C6 alkyl, and pendant ligands including functional group(s) providing further coordination to the metal center M. The precursors of the above formula are useful to achieve uniform coating of high dielectric constant materials in the manufacture of flash memory and other microelectronic devices.

摘要:
An aqueous-based composition and process for removing hardened photoresist and/or bottom anti-reflective coating (BARC) material from a microelectronic device having same thereon. The aqueous-based composition includes at least one chaotropic solute, at least one alkaline base, and deionized water. The composition achieves high-efficiency removal of hardened photoresist and/or BARC material in the manufacture of integrated circuitry without adverse effect to metal species on the substrate, such as copper, and without damage to low-k dielectric materials employed in the microelectronic device architecture.
摘要:
A method and composition for removing silicon-containing particulate material, such as silicon nitrides and silicon oxides, from patterned Si/SiO2 semiconductor wafer surfaces is described. The composition includes a supercritical fluid (SCF), an etchant species, a co-solvent, a surface passivator, a binder, deionized water, and optionally a surfactant. The SCF-based compositions substantially remove the contaminating particulate material from the wafer surface prior to subsequent processing, thus improving the morphology, performance, reliability and yield of the semiconductor device.

摘要:
A gas detector and process for detecting a fluorine-containing species in a gas containing same, e.g., an effluent of a semiconductor processing tool undergoing etch cleaning with HF, NF3, etc. The detector in a preferred structural arrangement employs a microelectromechanical system (MEMS)-based device structure and/or a free-standing metal element that functions as a sensing component and optionally as a heat source when elevated temperature sensing is required. The free-standing metal element can be fabricated directly onto a standard chip carrier/device package so that the package becomes a platform of the detector.
