Abstract
The electrical characteristics (I–V and I–t) of fluorinated polyimide dielectric films were measured as function of time, electric field and sample temperature and the results were discussed in view of existing conduction and charge-transport mechanisms. Experiments and analysis to elucidate conduction mechanisms at low and high electric fields were carried out. The results are presented and discussed. It is concluded that the bulk-limited Pool–Frenkel conduction mechanism is likely to dominate for the steady state current at high electric field above 1 MV cm-1, and in the range of low electric field below 1 MV cm-1, the Ohmic conduction is the main conduction mechanism. © 1998 Kluwer Academic Publishers
