Abstract
An experimental study of the p-type ion dopant BF2 + in silicon molecular beam epitaxy (MBE) is described. BF2 + was used to dope MBE layers during growth to levels ranging from 1 × 1016/cm3to 4 × 1018/cm3over a growth temperature range of 650°C to 1000°C. The layers were evaluated using spreading resistance, chemical etching, and secondary ion mass spectroscopy. Complete dopant activation was observed for all growth temperatures. Remnant fluorine in the epitaxial layer was less than 2 × 1016/cm3in all cases. Diffused p-n junction diodes fabricated in BF2 +-doped epitaxial material showed hard reverse breakdown characteristics.
