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.

Witryna(for Ribbon on Sacrificial Template) using plasma immersion ion implantation. The experiments were also carried out on FZ silicon as a reference. Boron was implanted at energies from 10 to 15 kV and doses from 1015 to 1016 cm−2, then activated by a thermal annealing in a conventional furnace at 900 and 950 C for 30 min. Witryna1 mar 1973 · Sheet resistivity as a function of surface oxide thickness for a 525 anneal. Boron dose and energy were 10" ions/cm2 and 70 keV, respectively. A best fit to theory is shown. activity level is a function of implant doping level.

Witryna1 sty 1988 · For each energy four boron doses were chosen ranging-from 1 10 u to 1 1012 ions/cm 2. One sample was kept unimplanted. Similarly for type 2 samples two ion energies 20 and 30 keV were used. Again for each energy value four boron doses, in the same range used in type 1 samples were taken. Here also one sample was kept … 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.
