Abstract
In one embodiment, an apparatus for fabricating nanostructure-based devices on a workpiece includes: a stage for supporting a workpiece, a radiating-energy source, and a feedstock delivery system. The workpiece has catalyst deposited thereon. The workpiece includes multiple work regions (e.g., dies). The feedstock delivery system is for delivery of feedstock gas to said catalyst. The feedstock delivery system is configured to directly heat catalyst on at least one die via simultaneously emitted multiple prongs of radiating energy. Preferably, the feedstock delivery system includes a feedstock heating system that is configured to heat the feedstock gas not merely by any global heating of a chamber containing the work region or any direct excitation of gas over the work region by the radiating energy.

19. A method for fabricating nanostructure-based devices on a workpiece, the workpiece including multiple work regions, the method comprising:
-
positioning a work region of said workpiece, and an energy emission system, in alignment for said energy emission system to radiate energy toward a surface of said work region, said surface being within a chamber;
flowing feedstock gas to said surface of said work region; and
emitting simultaneously multiple prongs of radiating energy from said energy emission system externally onto said surface of said die, to thereby heat catalyst on said surface of said die, wherein a nanostructure is formed at said heated catalyst. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)
