Abstract

The unprecedented success of information technology has been focused by semiconductor industry to advance at dramatic rate. Thermal issues are hastily becoming one of the most challenging problems in high-performance chip design due to ever-increasing device. In the analysis of heat transport of IC chip, Fourier's heat conduction mechanism was frequently used. It is known that, this equation suggests a presumption of infinite thermal propagation speed. Then non-Fourier heat conduction model was used to forecast the rapid transient heat conduction process. A number of traditional iterative and moments matching based solvers can be found to analyze the Fourier and non-Fourier heat conduction model such as Runge-Kutta (RK) and Asymptotic Waveform Evaluation (AWE) technique. The iteration based RK method is computationally expensive and the AWE moment matching is inherently ill-conditioned.  In present work, Tiknonov based Well-conditioned Asymptotic Waveform Evaluation (TWCAWE) technique has proposed to analyze the Fourier and non-Fourier heat conductions. The TWCAWE technique is successfully able to avoid the ill-conditioning moment matching and also 1.2 times faster compared to AWE.
