Abstract:
This paper presents calibration approach for our unified length/width-dependent MOSFET drain current (Ids) model [1] with the length/width-dependent threshold voltage (Vt) model [2] for technology characterization in the entire geometry/bias range for CMOS shallow trench isolation (STI) transistors. The model has been formulated with built-in physical effects to account for short-channel/ narrow-width effects while maintaining Gummel symmetry [3]. Through a one-iteration parameter extraction, the model can predict accurately the experimental data from a 0.11-_m CMOS STI technology wafer.
