Comparison of cw laser-annealed and electron-beam annealed Si

Abstract
Si samples implanted with As+ have been annealed with a modified commercial scanning electron microscope and with a scanning cw Ar+ laser. A comparison of these two techniques is presented, using electron-beam-induced current as a probe of minority-carrier effects. With a minimum of parameter optimization, it is found that electron-beam annealing is usually superior to laser annealing with respect to both lateral and vertical uniformity.
