Claim Text:
1. A method for forming a device structure on a substrate, comprising: forming a gate dielectric structure on the substrate using at least two sequential process steps: transferring the substrate between the second process chamber and the first process chamber through a transfer chamber of the processing system, wherein the transfer chamber is 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 second, distinct pumping element that 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 introducing the substrate to the processing system through a load lock distinct from said transfer chamber to allow introduction and removal of the substrate from the processing system.
