Abstract :
We have constructed fundamental theories for electronic properties and dielectric breakdown of gate insulator materials in nano-CMOS devices based on the Rigged QED theory and the regional density functional theory. Simulations about dielectric properties and reliability due to these theories have been carried out for SiO2, ZrO2, HfO2, ZrxSi1-xO2, HfxSi1-xO2, GdxOy, LaxOy, and SiOxNy through the modeling of nano-CMOS system such as crystal and amorphous thin films. Furthermore, we have reported development of the nucleus-electron multiple dynamics program codes following the Rigged QED theory.
