Abstract:
1. A processing system for use in forming at least part of a gate dielectric structure on a substrate, comprising: a first process chamber for forming a gate dielectric layer over the substrate, the first process chamber having a first pumping element configured to evacuate gas from the first process chamber; a second process chamber for introducing nitrogen atoms in the gate dielectric layer, the second process chamber having a second pumping element configured to evacuate gas from the second process chamber; a transfer chamber connected to the first process chamber via a first vacuum lock door and connected the second process chamber via a second vacuum lock door, the transfer chamber having a gas distribution system and a third, distinct pumping element configured to provide an ambient of uniform, laminar inert gas flow within the transfer chamber during transfer of the substrate between the first process chamber and the second process chamber; and a load lock distinct from said transfer chamber to allow introduction and removal of the substrate from the processing system.
