Abstract :
A quantized bands model capable to generate capacitance-voltage (C-V) curves of MOS capacitors was implemented and numerical details are discussed. This model is applied to the extraction of the dielectric constant of Al2O3 layers with known physical thicknesses by fitting experimental results. A comparison with a continuum band model is presented.
