D. Korzec et al., REMOTE DEPOSITION OF SCRATCH RESISTANT FILMS BY USE OF SLOT ANTENNA MICROWAVE PLASMA SOURCE, Thin solid films, 282(1-2), 1996, pp. 143-145
The slot antenna microwave plasma source is used for remote plasma dep
osition of scratch resistant films on polycarbonate substrates. A grid
separates the primary discharge from the process chamber. The monomer
hexamethyldisiloxan is distributed 5-50 mm over the substrate positio
ned 5-25 cm from the separation grid. With argon in the primary discha
rge a good sticking interface polymer layer grows. An additional amoun
t of oxygen leads to a quartzlike layer on top. Deposition rate is typ
ically 0.5 mu m/min. Rubber and tumble abrasion tests are used to char
acterise the scratch resistance.
