Web1 dec. 1976 · IONIZED-CLUSTER BEAM DEPOSITION The modified system for ionized-cluster beam deposition is shown in Fig. 1. The metal enters through the nozzles of the heated crucible into a high vacuum, and by adiabatic expansion metal molecules gather into vapour clusters consisting of 101-103 atoms. The ionized clusters are accelerated electrostatically to high velocities, and they are focused into a tight beam. The GCIB beam is then used to treat a surface — typically the treated substrate is mechanically scanned in the beam to allow uniform irradiation of the surface.
