Abstract: A process for determining the fludioxonil content in a liquid medium by performing a color reaction with [4-(dimethylamino)phenyl]methanol (p-DAB) or 4-Dimethylaminocinnamaldehyde (DMACA) and an acid in the presence of fludioxonil and obtaining a colorimetric reading for the resulting mixture after a period of time

Abstract: A method for plasma processing that includes: loading a dummy wafer between a focus ring positioned within a plasma process chamber; depositing a material layer over the focus ring by a plasma deposition process within the plasma process chamber; removing the dummy wafer from the plasma process chamber, and loading a substrate to be processed between the focus ring with the material layer within the plasma process chamber and performing a plasma process on the substrate.

Abstract: A method of high-throughput dry etching of silicon oxide and silicon nitride materials by in-situ autocatalyst formation. The method includes providing a substrate having a film thereon in a process chamber, the film containing silicon oxide, silicon nitride, or both silicon oxide and silicon nitride, introducing an etching gas containing fluorine and hydrogen, and setting a gas pressure in the process chamber that is between about 1 mTorr and about 300 mTorr, and a substrate temperature that is below about ?30° C. The method further includes plasma-exciting the etching gas, and exposing the film to the plasma-excited etching gas, where the film is continuously etched during the exposing.
