Implant boron dose

Semiconductor doping with boron, phosphorus, or arsenic is a common application of ion implantation. When implanted in a semiconductor, each dopant atom can create a charge carrier in the semiconductor after annealing. A hole can be created for a p-type dopant, and an electron for an n-type dopant. This modifies the conductivity of the semiconductor in its vicinity. The technique is used, for example, for adjusting the threshold voltage of a MOSFET. Witryna1 lip 1979 · Boron implantation to silicon dioxide, if the doses are small, results in re- duction of Q~ content. On the contrary, for larger doses Q~ increases. Boron implantation is followed by an increase of trap density in the silicon dioxide if only the dose exceeds an intrinsic concentration of traps in non-implanted mate- rial.
