We have analyzed the correlation between insulator surface copper contamination and time-dependent dielectric breakdown (TDDB) quantitatively for the first time. TDDB lifetime strongly depends on the copper contamination after CMP process, and it is important to control the redox potential to be less than -0.5 V vs. N…

For the size reduction of electric power equipment, an increase of electric field stress around solid insulators is carefully to be considered. The application of FGM (Functionally Graded Materials) with spatial distribution of dielectric permittivity (epsiv-FGM) will be an effective solution for this concern. In this…
