Abstract

This paper describes the thermally stimulated current(TSC) of PAAS spin coated film and the electrical properties of pre TSC measurement and after TSC test specimens. The TSC measurement were performed from room temperature to about $280^{\circ}C$ and the temperature was increased by $5^{\circ}C/min$ automatically. It shows that two peaks of TSC are observed at about $50^{\circ}C$ and about $160^{\circ}C$. Result of this measurement indicate that one peak; $50^{\circ}C$ is from alkyl group; other peak at $160^{\circ}C$ is due to alkyl and C-O group of PAAS. Addition to larger peak at about $160^{\circ}C$ is due to dipolemoment of PAAS film. This result is proved by DSC measurement of PAAS film. The electrical properties of pre and after TSC were measured by currant-voltage(l-V) characteristics. The current-voltage characteristics after TSC specimens are increased the conductivity. The electrical properties of pre-after TSC measurement specimen is in the middle of imidization of PAAS. Because of this result a thermal imidization was performed at $300^{\circ}C$ for 1 hour.
