Abstract:This paper presents a study on the dielectric behavior of SU-8 photoresist. We present measurements on the leakage current levels through SU-8 layers of varying thickness. The leakage current is dominated by thermionic emission. We have further determined the dielectric strength of SU-8 to be 4.4 MV cm−1. The remarkably high dielectric strength allows the material to be used for high-voltage applications.
