Abstract: A method and system for chemical vapor deposition (MO CVD) of a metal layer upon a spherical substrate at atmospheric pressure are disclosed. The method performs chemical vapor deposition of a metal layer such as aluminum or copper upon the semiconductor spherical substrate by using a reactor made of a material such as quartz. The semiconductor spherical substrate moves and spins through the reactor where it is heated by a frequency heater such as an infrared heater. The heater utilizes infrared power source operating at a wavelength between 1 and 3 microns where the power is substantially absorbed by the semiconductor spherical substrate and is substantially transmitted by the quartz.

Abstract: A method and apparatus for metal-organics chemical vapor deposition (MO CVD) of a metal layer upon a spherical substrate at atmospheric pressure are disclosed. The method includes pretreating the spherical substrate with a vapor of a first precursor in preparation for a deposition of a metal layer. The pretreated spherical substrate is then exposed to a thermally dissociated precursor of metal for depositing the metal layer onto the spherical substrate, wherein the exposure to the thermally dissociated precursor of metal provides a uniformly deposited metal layer coverage over the pretreated spherical substrate. The deposited metal layer is then annealed and cooled.
