Abstract
A new dry etching technique--development-free vapor photolithography was used to transfer pattern on silicon nitride film. Plasma enhanced chemical vapor deposition silicon nitride film and thin low pressure chemical vapor deposition silicon nitride film can be etched to get positive pattern. The difference of etching rate between exposed area and unexposed area was attributed to the concentration difference of accelerators which was realized through photochemical reaction. The reaction mechanism and other phenomena have also been discussed.
