This paper presents the directions for computer aided design, modelling and simulation of bendable MOSFET transistors towards futuristic bendable ICs. In order to compensate the bending stress a generalised geometry variation is discussed. Based on drain-current and threshold-voltage parameters varying under the bending stress, a Verilog-A compact model is proposed and describes I-V characteristics of a MOSFET in a standard 0.18-μm CMOS technology. This model has been compiled into Cadence environment to predict value and orientation of the bending stress. The proposed model validates against macro-model simulation results, and agrees for both the electron and hole conduction. It has been found that there is significant performance advantage in process-induced uniaxial stressed n-MOSFET, exhibiting a smaller drain-current variation and threshold voltage shift by monitoring the bending stress and changing the supply voltage.
