Then approximate analytic models of MOS devices for leakage current ( ΙR ), threshold voltage ( V ), transfer characteristics and transconductance ( g ) are proposed. NMOS device is T m taken for example, by using LabView (a tool for simulating) to carry out numerical simulation. Then some conclusions of the changes of these characteristic parameters in high temperature are achieved. These conclusions could be used as references in analyzing and designing high-temperature MOS device. Keywords: Semiconductor physics, MOS device, High-temperature characteristics, Approximate characteristics, Numerical simulation
