This paper describes the application of the Carrier Illumination technique to non-destructively measure dopant behavior
before and after annealing for 65nm technology. Patterned wafers were implanted with different SDE energy and
dosages. The detected signals from laser diode show good correlation with electrical performance (drive current,
overlap capacitance). Another crucial application is to in-line monitor the thermal process. By splitting spike anneal
temperature, we found detected signals were proportional to the junction depth of SIMS. The non-destructive, non-contact,
and small spot size nature of the CI measurement method is capable of tracing low energy implant and spike
anneal.
