Claim 13:
14. A processing method comprising:
positioning a substrate in a processing chamber comprising a gas distribution assembly including a plurality of elongate gas ports including a first reactive gas port and second reactive gas port, the first reactive gas port in fluid communication with a first reactive gas comprising WxCl5x or WxCl6x and the second reactive gas port in fluid communication with a second reactive gas comprising hydrogen, the gas distribution assembly flowing both the first reactive gas and the second reactive gas into the processing chamber simultaneously;
passing the second reactive gas across a heating element to generate hydrogen radicals in the second reactive gas; and
sequentially exposing at least a portion of the substrate to the first reactive gas and the hydrogen radicals in the second reactive gas to form a tungsten film on the substrate.
