Abstract: Embodiments disclosed herein include a semiconductor processing tool. In an embodiment, the semiconductor processing tool comprises a chamber, a pedestal in the chamber, and a first gas feed system on a first side of the pedestal. In an embodiment, the first gas feed system comprises a first exhaust line with a first valve to open and close the first exhaust line, and a first source gas feed line with a second valve to open and close the first source gas feed line. In an embodiment, the semiconductor processing tool further comprises a second gas feed system on a second side of the pedestal. In an embodiment, the second gas feed system comprises a second exhaust line with a third valve to open and close the second exhaust line, and a second source gas feed line with a fourth valve to open and close the second source gas feed line.
