Witryna1 lip 2000 · A boron buried layer was used as a detector for interstitial supersaturation in the samples. Boron dose ranged from 1×10 14 to 1×10 15 cm -2 and N 2+ dose from 5×10 13 and 5×10 14 cm -2. The energies were chosen such that the location of the nitrogen and boron peaks matched. 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.

Witryna27 lip 2011 · The slightly under-dosing of the B 18 H 22 implant in this case could be caused by a difference in dose retention between B18 and monomer boron. For low-energy implants, as dose increases, the fraction of dopant loss increases due to the sputtering, where near surface atoms leave the target during implantation due to … 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.
