This course assumes that you have studied solid state devices covering topics: concentration and transport of carriers in semiconductors, analysis of diodes, BJTs and MOSFETs leading to simple current-voltage equations for these devices. This course shall discuss qualitative model of semi-classical bulk transport; the electromagnetic field and transport equations of this semi-classical bulk transport; drift-diffusion transport model, equations, boundary conditions, mobility and generation/recombination; the characteristic times and lengths, which are used in device modeling; the energy band diagrams, which is a very important tool both for representing conditions in a device and for analyzing conditions in a device; the 9 steps of deriving a device model; modeling of the MOSFET; structure and characteristics and qualitative understanding of the operation of a MOSFET.
