This tutorial covers the modeling of IC components and semiconductor devices for performing circuit design tasks for VLSI based on SPICE-like (AIM-SPICE) circuit modeling systems. A wide range of basic and universal SPICE models are presented, both traditional and new devices, including bipolar and MOS transistors, hetero-bipolar transistors, thin-film transistors based on polysilicon and amorphous silicon, field-effect transistors based on GaAs with a Schottky barrier. The presented theoretical material is accompanied by detailed examples.
