In order to fabricate micro textured polymer plate, some kinds of ions were irradiated to the substrate by using an Electron Cyclotron Resonance (ECR) ion shower apparatus. Surface morphology of specimens was observed by SEM, and measured by AFM. We obsearved a lot of micro polymer brushes on the substrate. The surface roughness of untreated specimen were increased and reached to 248 nm by N_2 ion irradiation. We have used Argon, Nitrogen and Oxygen ions. Oxygen ions shows most effective to etch than other two ions. Also we measured the contact angle of water on the surface of specimens with optical microscope. The contact angle of untreated specimen were decreased and reached to 8 deg. by N and O ion irradiation. After the irradiation, we conducted sliding friction test between ion irradiated polycarbonate slider against flat polycarbonate specimen. It was observed that friction coefficient of ion irradiated polycarbonate slider shows lower friction than flat polycarbonate specimen under mixed lubrication condition in water.
