Anti-Corrosion Coatings for Equipment Parts

The challenge

The fluorine plasma used in semiconductor process equipment causes corrosion in the chamber parts. The existing protective coatings were porous and had particle generation issues inside the wafer processing chamber. The parts are complex in shape and larger than usual ALD substrates.
