E. Basaran et al., ELECTROCHEMICAL CAPACITANCE-VOLTAGE DEPTH PROFILING OF HEAVILY BORON-DOPED SILICON, Journal of crystal growth, 157(1-4), 1995, pp. 109-112
The electrochemical capacitance-voltage profiling (eCV) technique is e
mployed to measure the carrier concentration in heavily boron-doped Si
, grown by molecular beam epitaxy. Secondary ion mass spectrometry (SI
MS) and Hall measurements are also carried out for comparison. The car
rier concentrations obtained by eCV match well with the Hall measureme
nts. The results indicate that the eCV technique is capable of probing
carrier concentrations well into the 10(20) cm(-3) range with a good
precision. The relative merits of the eCV and SIMS depth profiling are
shown to be useful in the cm analysis of boron incorporation behaviou
r at doping levels above solubility limits.
