The photovoltaic effect on differential capacitance signals of low-energy BF2+ implanted silicon wafers was studied using scanning capacitance microscopy (SCM). The observed junction image exhibited a narrower junction width due to the photovoltaic effect on the junction region. The photovoltaic effect deteriorates the accuracy of junction characterization, in particular for ultrashallow junctions and lower band-gap semiconductors.
