Laser ablation as a processing technique for metallic and polymer layered structures

A study of the laser ablation process for application in processing metallic and polymer layered structures is presented. The central result of this study is that, by operating with laser pulses of different fluences, it is possible to selectively remove polymer overlayers on metallic films and metallic films from polymer layers, provided the metallic films are sufficiently thin. Careful choice of the fluence allowed both of these processes to …
