Implant boron dose

Witryna2 maj 1996 · For off-axis implants, there is a definite indication of a dose rate effect for boron, but it is smaller than that observed for onaxis implants. However, the effect is … 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.
