  • Patent number: 10526700
    Abstract: The present inventors have conceived of a multi-stage process gas delivery system for use in a substrate processing apparatus. In certain implementations, a first process gas may first be delivered to a substrate in a substrate processing chamber. A second process gas may be delivered, at a later time, to the substrate to aid in the even dosing of the substrate. Delivery of the first process gas and the second process gas may cease at the same time or may cease at separate times.
