HIGHLY ETCH SELECTIVE AMORPHOUS CARBON FILM

Methods and techniques for deposition of amorphous carbon films on a substrate are provided. In one example, the method includes depositing an amorphous carbon film on an underlayer positioned on a susceptor in a first processing region. The method further includes implanting a dopant or the inert s...

Zusammenfassung:Methods and techniques for deposition of amorphous carbon films on a substrate are provided. In one example, the method includes depositing an amorphous carbon film on an underlayer positioned on a susceptor in a first processing region. The method further includes implanting a dopant or the inert species into the amorphous carbon film in a second processing region. The implant species, energy, dose & temperature in some combination may be used to enhance the hardmask hardness. The method further includes patterning the doped amorphous carbon film. The method further includes etching the underlayer.
