Fundamental modelling of semiconductor power devices

With the introduction of relatively cheap and powerful computers and a range of comprehensive software packages, many device manufacturers now make extensive use of computer aided analysis in the design of new devices. Although these techniques are beginning to find application in large area power devices, there is still much work to be done in determining necessary and sufficient conditions for accurate and reliable simulation. Discretised versions of semiconductor device equations must be formulated consistently across the full coupled set of equations, and an initially adequate mesh generation may become invalid with development of space-charge regions during transients
