I would like to etch silver or aluminum film in PlasmaQuest. Does anyone
have experience of that? I would be grateful if someone would let me know
the etching conditions for these films.
Details of my experiment are as follows;
material of film: Al or Ag
thickness of film : 20-100 nm.
Mask : PMMA (t=300 nm)
substrate: GaAs wafer
Patterns: Ph.C-like (a =250 nm, Φ = 50-150 nm)
Any suggestion is greatly appreciated.
