To estimate the influence of electrical properties due to the poly back seal(PBS). we were investigated defect density in surface by deposition thickness and breakdown voltage in specimens. Deposition thickness of specimen is prepared from 7,000[$\AA$] to 13,000[$\AA$], respectively. From the results, it is confirmed that PBS deposition thickness of 10,000[$\AA$] among the specimen is decreased defect density by contribution of the gettering effect.
