ABSTRACT:
The present invention provides improvements to the use of silyating agents in semiconductor processing. More particularly, the silyating agents may be provided in combination with a substantially non-flammable ether, so that the combination is substantially non-flammable. Additionally, the silyating agent may be utilized in vapor form, or applied in conjunction with the electromagnetic radiation. Each of these embodiments can enhance the usability of the silyating agent, i.e., by rendering the silyating agent more safe, more easily utilized in a variety of processing equipment and/or by enhancing the passivation efficacy/efficiency of the silyating agent.
