Abstract

Transparent aluminum oxide films were deposited on polycarbonate (PC) substrates by inductively coupled plasma (ICP) assisted reactive sputtering. the oxygen flow rate was regulated by controlling the target voltage with a proportional integrate derivative controller. The PC substrate was treated with plasma prior to the deposition in order to the enhance the adhesive strength of the $Al_2O_3$ film. The characteristics of hardness, structure, density, transmittance, deposition rate, surface roughness and residual stress were investigated to estimate the possibility for the hard coating.
