A parallel numerical solution of the drift-diffusion model for simulation of semiconductor devices based on the local meshless method is demonstrated in this paper. The problem is usually discretized and solved through nonlinear solvers with an iterative approach. Numerical difficulties inherited from convection-dominated processes are also associated with high gradients and oscillations in the solution. The difficulties can be alleviated by artificial dissipation schemes and by other stabilization approaches that require complex computation to improve solution convergence. We propose a simple numerical approach with a local coupling and without special treatments of nonlinearities. The spatial discretization is performed through the local meshless method to allow more freedom in geometric shapes. We demonstrate that the proposed approach is simple to implement and suitable for parallel implementation.
