Abstract :
The roadmap for ultra-shallow junction formation (USJ) includes implant spike anneal and solid-phase epitaxial re-growth. The roadmap for the junction contacts foresees transition from CoSi2 to NiSi. The processes in the roadmap require extreme capabilities from RTP tools: heat-up and cool-down rates of hundreds of degrees per second, no pattern/emissivity dependence, precise temperature control, and operation at low temperature (starting from 200°C for NiSi formation). This paper describes a tool which enables continuity in the development of USJ for current and future technology nodes. It provides high ramp rates (300-900°C/sec), and operates in the temperature range of 100-1100°C with precise temperature control.
