Patent ID: 8235002

Claim:
A plasma assisted apparatus for organic film deposition, comprising: a plasma chamber, capable of thermally cracking a precursor in the plasma chamber, comprising: an aperture in a wall of the plasma chamber; an outlet defined within said aperture for the thermally cracked precursor to flow through; a working gas inlet channeled to a working gas inletting device for introducing working gas into the plasma chamber for thermal cracking; a flow guiding device disposed at the outlet of the plasma chamber comprising: a gas inlet device, disposed through the center portion of the flow guiding device, for introducing thermally cracked precursor into the plasma generator; a shrinking end, environing said gas inlet device and channeled with said plasma chamber, to receive a combination of thermally cracked working gas and precursor from said plasma generator; and an expanding end, environing said gas inlet device, to receive said combination of thermally cracked working gas and precursor from said shrinking end and adjust the gas flow angle of said thermally cracked precursor when leaving said plasma chamber; wherein said flow guiding device is configured to direct said thermally cracked precursor to enter and flow through said gas inlet device to said plasma generator in a specific direction, and direct said combination of thermally cracked working gas and precursor to enter and flow through the shrinking end of the flow guiding device in the opposite direction to adjust the gas flow angle by said expanding end; and a deposition chamber, being channeled with the plasma chamber for receiving said combination of thermally cracked working gas and precursor via each of said outlet, said aperture, and said flow guiding device, such that said combination of thermally cracked working gas and precursor flows both within the flow guiding device as well as through the outlet of the aperture external to the flow guiding device as the thermally cracked working gas and precursor flows from the plasma chamber into the deposition chamber; wherein said outlet is defined by the region of said aperture not spatially occupied by said flow guiding device; wherein the deposition chamber further comprises a substrate device, being provided for the thermally cracked precursor to deposit thereon to form an organic film.
