The invention provides a method for forming a patterned material layer on
a structure, by condensing a vapor to a solid condensate layer on a
surface of the structure and then localized removal of selected regions
of the condensate layer by directing a beam of energy at the selected
regions, exposing the structure at the selected regions. A material layer
is then deposited on top of the solid condensate layer and the exposed
structure at the selected regions. Then the solid condensate layer and
regions of the material layer that were deposited on the solid condensate
layer are removed, leaving a patterned material layer on the structure.
