  • Abstract
    The lateral diffusion of dopants in a TiSi2 salicide process was studied for various BPSG reflow RTP anneals. Lateral diffusion of arsenic was detected for anneals above 1000°C (20 sec.) whereas no boron diffusion could be observed for anneals up to 1060°C. A novel ``weakly doped gate´´ test structure proved to be a sensitive detector of lateral diffusion.
