Abstract
A gas system includes an enclosure, a process gas metering valve, a shutoff valve, and a flow switch. The process gas metering valve arranged within the enclosure to flow a process gas to a process chamber of a semiconductor processing system. The shutoff valve is connected to the process gas metering valve to fluidly separate the process gas metering valve from a process gas source. The flow switch is operably connected to the shutoff valve to cease flow of the process gas to the process chamber of the semiconductor processing system using the shutoff valve according to flow of a gas traversing the flow switch. Semiconductor processing systems, gas control methods, and gas system kits are also described.
