Abstract
Poly(tetra¯uoroethylene) (PTFE) is notable for its non-adhesive and non-reactive properties. A number of technologies can
potentially bene®t from the application of PTFE, but these characteristics restrict the ability to structuring its surface.
In this paper, we present results on two ultraviolet photon assisted treatments of PTFE. The originally poor adhesion was
Ã
signi®cantly improved by both 172 nm excimer lamp and 193 nm excimer laser assisted surface treatments. While Xe2 lamp
irradiation, applied in a modest vacuum environment, was suf®cient by itself to improve adhesion, the ArF laser process was
only effective when the irradiated interface was in conta
