Abstract
A cluster source is used to assist charged particle beam processing. For example, a protective layer is applied using a cluster source and a precursor gas. The large mass of the cluster and the low energy per atom or molecule in the cluster restricts damage to within a few nanometers of the surface. Fullerenes or clusters of fullerenes, bismuth, gold or Xe can be used with a precursor gas to deposit material onto a surface, or can be used with an etchant gas to etch the surface. Clusters can also be used to deposit material directly onto the surface to form a protective layer for charged particle beam processing or to provide energy to activate an etchant gas.
