While plasma etching of wafers has been a mainstay of the semiconductor industry for more than 25 years, only in the last decade has dry-etch processing become interesting to mask manufacturers. The reason for the late introduction of this technology becomes obvious when the methodologies used to image silicon wafers are examined.
