Abstract:
This invention concerns a system for delivering multiple different chemicals to a process tool, comprising: a first supply canister connected to a first supply manifold that connects to a process line; a second supply canister connected to a second supply manifold that connects to the process line.
Abstract:
Zirconium precursors of the formulae (I) and (II). Such precursors are liquids at room temperature, and can be employed in vapor deposition processes such as ALD to form zirconium-containing films, e.g., high k dielectric films on microelectronic device substrates. The zirconium precursors can be stabilized in such vapor deposition processes by thermal stabilization amine additives.
Abstract:
A canister guard for preventing liquid contamination of an oulet to a canister containing liquid. The canister guard may include baffles extending from a sidewall. Additionally, the canister guard may be configured to be replacable or for retrofitting to conventional liquid chemical containing canisters.

Abstract:
A chemical delivery system (500) which utilizes a purge technique which may utilize a variety of combinations of a medium level vacuum source, a hard vacuum source, and/or a liquid flush system (506). Also a chemical delivery system is disclosed that may be provided with a heater system for heating the chemical delivery system.
Abstract:
A bulk chemical delivery system, comprising: a bulk chemical canister that is connected to at least one manifold box, wherein each manifold box has at least two output lines, wherein each output line connects to a secondary canister. In non-limiting representative example, the bulk chemical canister may have a capacity of 200 liters. Also disclosed are novel manifolds for use in delivering chemicals from canisters and a transportation/containment cart.
