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. green realty anna maria islandWitryna4 cze 1998 · The suprem model of an exponential for the channeling tail of boron implants in crystalline silicon is fairly good for fluences greater than about 10 15 cm … fly\\u0027s tieWitrynaIntegration of High Dose Boron Implants - Modification of Device Parametrics through Implant Temperature Control .
