摘要：

Raman spectra of polyimide films were studied before and after being irradiated with 308 nm excimer laser pulses in order to understand the conductivity increase induced by ultraviolet irradiation. Changes in the chemical structure of polyimide were observed. A possible mechanism responsible for the ultraviolet induced conductivity increase is proposed. This letter also shows that the Raman microprobe can be very useful in the analysis of the molecular structure of polymers.
