Abstract
MOS and MIS capacitor has been extensively studied in past several decades by many authors. It has been expected to reveal how basic physics relate electron device operation. In this structure, several physical phenomena co-work and then exhibit the electrical properties measured in IV- and CV-characteristics. On the other hand, the conventional models were established separately for the inversion layer (positive gate voltage), the depletion region (negative-low gate voltage), and the accumulation region (negative-high gate voltage). In addition, actual MOS/MIS samples have interfacial transition layer where physical properties are gradually changed from Si to oxide or other dielectric, the varying composition ratio of molecules and local traps owing to atomistic dangling bonds through dielectric layer. What will happen if we self-consistently unify all the physical models that are separately developed?
