摘要
Silicon specimens have been implanted with 1 multiplied by 10**1**6 and 5 multiplied by 10**1**6 As** plus ions/cm**2 and annealed with a pulsed ruby laser, thus giving rise to a supersaturated solution. Subsequent heat-treatments carried out in an inert ambient at either 450 degree or 900 degree C led to a strong deactivation of the dopant. The physical nature of the inactive arsenic has been investigated by transmission electron microscopy (TEM), both in the weak beam and the high resolution imaging modes. For both doses and annealing temperatures, the presence of precipitates, having a diameter ranging from 1. 5 to 3 nm, has been observed.
