Practical Atomistic Dopant Diffusion Simulation of Shallow Junction Fabrication Processes and Intrinsic Fluctuations for sub-100nm MOSFETs

Hane M., Ezaki T., Ikezawa T., NEC Corporation, JP

We studied sophisticated shallow junction fabrication processes, i.e. spike-annealing and flash-lamp annealing, using our recently developed atomistic dopant diffusion simulator. Through its use of kinetic Monte Carlo procedure, considering all the possible charged species and [...]
