Abstract
Voltage nonlinearity is a crucial performance parameter of MIM capacitors for RF, analog and mixed signal IC applications. In present work, the fabrication and characterization of anodic high-k MIM capacitors are reported in detail and modeling of nonlinearity coefficient of capacitance is developed using polarization of induced dipoles. The model agrees with experimental results for various high-k dielectric MIM capacitors. It explores the origin of nonlinearity in capacitance–voltage characteristics of MIM capacitors and also predicts the potential requirements to meet the ITRS requirements.
