Abstract:
A chemical vapor deposition process comprising the steps of:positioning a target within a chamber, said target comprising CVD precursor particles;transferring heat energy to a selected target area of said target to induce a predetermined temperature increase in said selected target area, wherein said predetermined temperature increase is characterized by a predetermined heating rate, and wherein said predetermined heating rate is selected such that said heat energy causes the desorption of at least one CVD precursor particle to define a precursor desorption region and such that a substantial portion of said heat energy is not transferred to the internal energy modes of said CVD precursor particle;positioning a deposition substrate in particulate communication with said precursor desorption region;directing said desorbed precursor particle towards a surface of said deposition substrate; andcausing said desorbed precursor particle to decompose on said deposition substrate surface.
