?Reverse? annealing mechanism in ion-doped silicon layers subjected to electron beam heating

Monocrystalline silicon was implanted with 60 keV fluorine and 20 keV boron ions and annealed. Carrier profile, fluorine and boron redistribution, and the parameters of p+-n junctions were investigated. In ion implanted Si two specific regions were observed in which peculiarities in carrier concentration, resistivity, and F atoms redistribution occurred. It was reasoned that the “under-surface” specific region is enriched with vacancy-type defects while the “amorphous/crystalline (a/c) interface” region is enriched with interstitial type defects. After annealing at a temperature corresponding to the reverse annealing phenomenon, boron atoms were activated in the “under-surface” and deactivated in the “a/c interface” region. The possibility of PMOS transistor fabrication with ultrashallow p+-n junction (60 nm) and low leakage current by F++B+ implantation and low temperature (600–700) °C annealing by using this phenomenon was demonstrated.
