WebThe interface obtained between the high k dielectric and the semiconductor substrate, critical for stability and feasibility of the experimental devices, is analyzed using both numerical calculation of the ideal capacitance - voltage (C-V) characteristics of the MOS capacitors and experimental data obtained at high frequency (500 kHz). The refractive index (n) and extinction coefficient (k) are related to the interaction between a material and incident light, and are associated with refraction and absorption (respectively). They can be considered as the “fingerprint of the material". Thin film material coatings on various substrates provide important functionalities for the microfabrication industry, and the n, k, as well as the thickness, t, of these thin film constituents must be measured and controlled to allow for r…
