Design and implementation of semiconductor multi-physical parallel computing program JEMS-CDS-Device

Aiming at the research requirements of multi-physical effects mechanism of devices in complex electromagnetic environment, a parallel computing program for semiconductor multi-physics effects, JEMS-CDS-Device, is developed. This paper introduces the architecture design and implementation technology of JEMS-CDS-Device. The program is based on the unstructured grid parallel framework-JAUMIN. It uses the finite volume method (FVM) to discretize and uses the Newton method to get fully coupled solution of the 'electric-carrier transport-thermal' problem. The program which adopts the 'kernel + algorithm library' form architecture, supports 2D/3D unstructured mesh, and can solve problems of tens of millions of degrees of freedom parallelly. It supports extended development of physical effect equations, discrete algorithms, material physics models, etc. (authors)
