Abstract: A multi-step method for depositing ruthenium thin films having high conductivity and superior adherence to the substrate is described. The method includes the deposition of a ruthenium nucleation layer followed by the deposition of a highly conductive ruthenium upper layer. Both layers are deposited using chemical vapor deposition (CVD) employing low deposition rates.

Abstract: A method of passivating a CMP composition by dilution and determining the relationship between the extent of dilution and the static etch rate of copper. Such relationship may be used to control the CMP composition during the CMP polish to minimize the occurrence of dishing or other adverse planarization deficiencies in the polished copper, even in the presence of substantial levels of copper ions in the CMP composition and at the copper/CMP composition interface.

Abstract: Vaporizable material is supported within a vessel to promote contact of an introduced gas with the vaporizable material, and produce a product gas including vaporized material. A heating element supplies heat to a wall of the vessel to heat vaporizable material disposed therein. The vessel may comprise an ampoule having a removable top. Multiple containers defining multiple material support surfaces may be stacked disposed within a vessel in thermal communication with the vessel. A tube may be disposed within the vessel and coupled to a gas inlet. Filters, flow meters, and level sensors may be further provided. Product gas resulting from contact of introduced gas with vaporized material may be delivered to atomic layer deposition (ALD) or similar process equipment. At least a portion of source material including a solid may be dissolved in a solvent, followed by removal of solvent to yield source material (e.g., a metal complex) disposed within the vaporizer.

Abstract: A deposition process to form a conformal phase change material film on the surface of a substrate to produce a memory device wafer comprises providing a substrate to a chamber of a deposition system; providing an activation region; introducing one or more precursors into the chamber upstream of the substrate; optionally introducing one or more co-reactants upstream of the substrate; activating the one or more precursors; heating the substrate; and depositing the phase change material film on the substrate from the one or more precursors by chemical vapor deposition. The deposited phase change material film comprises GexSbyTezAm in which A is a dopant selected from the group of N, C, In, Sn, and Se. In one implementation, the process is carried out to form GST films doped with carbon and nitrogen, to impart beneficial film growth and performance properties to the film.
Abstract: Precursors useful for vapor phase deposition processes, e.g., CVD/ALD, to form metal-containing films on substrates. The precursors include, in one class, a central metal atom M to which is coordinated at least one ligand of formula (I): wherein: R1, R2 and R3 are each independently H or ogano moieties; and G1 is an electron donor arm substituent that increases the coordination of the ligand to the central metal atom M; wherein when G1 is aminoalkyl, the substituents on the amino nitrogen are not alkyl, fluoroalkyl, cycloaliphatic, or aryl, and are not connected to form a ring structure containing carbon, oxygen or nitrogen atoms. Also disclosed are ketoester, malonate and other precursors adapted for forming metal-containing films on substrates, suitable for use in the manufacture of microelectronic device products such as semiconductor devices and flat panel displays.

Abstract: A fluid storage and dispensing vessel having associated therewith a colorimetric member that is effective to change color in exposure to leakage of a gas contained in the vessel. The colorimetric member may be constituted by a film, e.g., of a shrink-wrap character, that contains or is otherwise associated with a colorimetric agent undergoing color change in exposure to fluid leaking from the vessel. Such shrink-wrap film may be applied to a portion of the vessel susceptible to leakage, or alternatively to the entire vessel, so that the film is colorimetrically effective to indicate the occurrence of a leakage event by visually perceptible change of color.
