A process for modifying a surface of a substrate is provided that includes supplying electrons to an electrically isolated anode electrode of a closed drift ion source. The anode electrode has an anode electrode charge bias that is positive while other components of the closed drift ion source are electrically grounded or support an electrical float voltage. The electrons encounter a closed drift magnetic field that induces ion formation. Anode contamination is prevented by switching the electrode charge bias to negative in the presence of a gas, a plasma is generated proximal to the anode electrode to clean deposited contaminants from the anode electrode. The electrode charge bias is then returned to positive in the presence of a repeat electron source to induce repeat ion formation to again modify the surface of the substrate. An apparatus for modification of a surface of a substrate by this process is provided.

In a method for imaging a solid state substrate, a vapor is condensed to an amorphous solid water condensate layer on a surface of a solid state substrate. Then an image of at least a portion of the substrate surface is produced by scanning an electron beam along the substrate surface through the water condensate layer.

Then one or more regions of the layer can be locally removed by directing an electron beam at the regions. A material layer can be deposited on top of the water condensate layer and any substrate surface exposed at the one or more regions, and the water condensate layer and regions of the material layer on top of the layer can be removed, leaving a patterned material layer on the substrate.
