Abstract:
We have investigated the fabrication of liquid crystal polymer (LCP) thin films by thermal evaporation, and pulsed laser deposition (PLD). Due to the carbonization of LCP, no films were fabricated by thermal evaporation. The laser desorption time-of-flight mass spectra of a LCP target exhibited that the main ablation species were the fragments of the LCP in the case of low laser fluence, indicating the possibility of film fabrication by PLD. Thin films fabricated by PLD using a KrF excimer laser have a pale yellow color and a surface roughness of 1 nm, as measured by atomic force microscopy. The spectra obtained by Fourier transform infrared spectroscopy exhibit a peak corresponding to carbonyl bond at approximately 1730 cm -1 , indicating a polyester structure similar to that of the original LCP. The breakdown field of the films was 1 MV/cm. We demonstrate that this film acts as a passivation films for organic field-effect transistors.
