Abstract:
An apparatus for producing a printed circuit board on a substrate, has a table for supporting the substrate, a function head configured to effect printing conductive and non-conductive materials on the substrate, a positioner configured to effect movement of the function head relative to the table, and a controller configured to operate the function head and the positioner to effect the printing of conductive and non-conductive materials on the substrate. The apparatus optionally has a layout translation module configured to accept PCB files or multilayer PCB files to printing data for controlling the function head to print conductive material and nonconductive material onto the substrate. Conductive traces having varying thickness may be produced on a common substrate. Conductive regions are printed to electrically isolate traces and optional to present an approximately level surface.

Abstract:
A method is described of controlling contamination of a surface exposed to a carbonaceous material and ionising radiation, such as EUV radiation, DUV radiation or electrons. The method comprises cyclically supplying to the surface a first gas comprising an oxidising species, for example NO, for reacting with carbonaceous deposits formed on the surface from the carbonaceous material, followed by a second gas comprising a reducing species, for example CO, for reacting with oxidising species on the surface.
