Abstract :
The letter describes the fabrication procedure and the electrical properties of a double polysilicon plate capacitor with composite SiO2/Si3N4 insulators. The presence of the Si3N4 layer allows elimination completely of low-voltage breakdown events and reduces the leakage current to the 10¿9 A/cm2 level. Different layout configurations are compared based on the evaluation of experimental data.
