Polyimide (PI) thin films of about 300 nm in thickness are fabricated by vapor deposition polymerization (VDP) from pyromellitic dianhydride (PMDA) and 4,4'-diaminodiphenylether (DDE). The structure of the films obtained is analyzed by means of infrared absorption spectra (IR spectra) and X-ray diffraction. The IR spectra show that the films are changed into PI by curing through the precursor, polyamic acid (PAA). The relation between the imidization of the films and the electrical conduction is examined. The results show that as imidization caused by curing the films proceeds, the current is decreased. It is therefore suggested that the residual PAA in PI thin films affects the electrical conduction. An attempt is also made to apply a model of ionic hopping conduction to the electrical conduction data.
