System and method for the holographic deposition of material
An apparatus and method for hologram induced deposition of material for use in the formation of three-dimensional structures is described. An electromagnetic energy source may be directed in the form of a hologram to a process chamber with a medium. The medium may be an organometallic gaseous medium. The hologram may induce the medium to form a solid structure associated with the shape of the hologram. The pressure of the gaseous medium may range from subatmospheric to greater than 100 psi. Alternatively, the medium may be a liquid polymer, a solid particle, or others. The hologram may be formed with an LCD panel or other means. Further, a holographic movie may be projected into one or more mediums to form complex three-dimensional structures.
1. An apparatus to deposit a three-dimensional structure comprising:
a holographic projector comprising a laser source supplying a laser beam directed via optics to a phase spatial light modulator to project a series of holograms; and
a processing chamber, wherein the processing chamber further comprises:
a window, wherein the window is transparent to the holograms;
a plane on which the holograms are imaged;
an inlet to receive gas precursors from a gaseous delivery system, wherein the gas precursors comprise varying gas components, and wherein the hologram imparts energy to dissociate the gas precursors causing dissociated gas precursors to deposit in the plane in a pattern corresponding to the hologram;
a laser light source to generate coherent collimated electromagnetic energy;
a computer driven phase plate placed in a path of the coherent collimated electromagnetic energy to the hologram operable to generate holograms at varying wave lengths directed into the processing chamber to deposit multiple definition compounds in the plane; and
an outlet to exhaust effluent from the processing chamber.
2. The apparatus of claim 1 further comprising a second holographic projector configured to project a second series of holograms into the gaseous medium to function with the first series of hologram.
3. The apparatus of claim 1 , wherein the energy to dissociate gas precursors corresponds to a wavelength of electromagnetic energy used to project the series of holograms.
4. The apparatus of claim 1 , wherein the energy to dissociate gas precursors corresponds to absorption bands of the gas precursors.
5. The apparatus of claim 1 , wherein the gaseous medium pressure within the processing chamber is maintained at about 100 pounds per square inch.
6. The apparatus of claim 1 , wherein an intensity of the series of holograms is manipulated to manipulate a deposition rate of the dissociated gas precursors.
7. The apparatus of claim 1 , wherein the series of holograms are projected onto a stage within the processing chamber.
8. The apparatus of claim 7 , wherein the stage is thermally biased.
