Plasma etch modeling using optical emission spectroscopy

In integrated circuit manufacturing, photolithography or optical lithography is a general term used for techniques that use light to produce minutely patterned thin films of suitable materials over a substrate, such as a silicon wafer, to protect selected areas of it during subsequent etching, deposition, or implantation operations. Typically, ultraviolet light is used to transfer a geometric design from an optical mask to a light-sensitive chemical (photoresist) coated on the substrate. Th… WebJan 1, 2007 · An endpoint detection algorithm based on principal component regression is developed for the multi-step plasma etching process with the whole optical emission spectra data. Because many endpoint detection techniques use a few manually selected wavelengths, noise render them ineffective and it is hard to select important wavelengths.
