The capacitance characteristics of polyimide thin films by VDP Method

Polyimide thin films were fabricated through the vapor deposition polymerization method, and the structure and capacitance characteristics of them were investigated in detail. It was found that the chemical structure and uniformity of the film could be stabilized with curing. The peaks of $720cm^{-l},\;1380cm^{-1}\;and\;1780cm^{-1}$ show C=O stretch mode, C-N stretch mode and carbonyl stretch mode, and those of polyimide which cured over $300^{\circ}C$ were fixed. It was found that capacitance was changed in proportion to temperature.
