We have studied charge trapping in tetraethylorthosilicate (TEOS) based phosphorous doped silicon glass (PSG) films deposited by plasma enhanced chemical vapor deposition (PECVD) using electron spin resonance and capacitance voltage measurements. The results indicate that these films trap electrons and holes very well. The charges appear to be trapped in phosphorus and carbon related centers as well as in E' centers. The carbon related centers are unique to the TEOS films.
