Abstract: A corrosion resistant gas cylinder and gas delivery system includes an electroless nickel-phosphorous layer overlying the inner surface of a steel alloy cylinder. The nickel-phosphorous layer has a thickness of at least about 20 micrometers and a porosity of no greater than about 0.1%. The electroless nickel-phosphorous layer has a phosphorous content of at least about 10% by weight and a surface roughness of no greater than about 5 micrometers. Prior to introducing liquefied gas into the gas cylinder, a cleaning process is carried out using a two-step baking process to clean the surface of the nickel-phosphorus layer. The nickel-phosphorous layer substantially reduces the contamination of liquefied corrosive gasses stored in the gas cylinder by metal from the steel wall surface underlying the nickel-phosphorous layer. Metal contamination levels of less than about 55 ppb of iron, 10 ppb of chromium, and 5 ppb of nickel by weight can be maintained in liquefied corrosive gasses stored for an extended period of time in the electroless nickel-phosphorus plated gas cylinder.

Abstract: A microstructured electrode coupled with an analytical method designed to simulate the actual conditions on the wafer and to measure critical parameters such as mass transfer of the active plating components, deposition rates of the copper in the plating bath solutions, and/or additive concentration is disclosed. Thus, an offline method for process control is provided. Additionally, the electrode and method can be incorporated into a copper interconnect bath tool or copper interconnect bath distribution system for online control of the process chemistry. The microstructured electrode design consists of a patterned electrode surface that simulates the dimensions of the interconnects and vias. The analytical method can be any type of method that allows diffusion or kinetic information to be obtained, such as electrochemical impedance, electrochemical noise, and other voltammetric or galvanostatic methods.
