A methodology for deep sub-0.25 μm CMOS technology prediction

We present a novel methodology for characterization of sub-quartermicron CMOS technologies. It involves process calibration, device calibration employing two-dimensional device simulation and automated Technology Computer Aided Design (TCAD) optimization and, finally, transient mixed-mode device/circuit simulation. The proposed methodology was tested on 0.25 μm technology and applied to 0.13 μm technology in order to estimate ring oscillator speed. The simulation results show an excellent agreement with available experimental data
