    • A gas detector and process for detecting a target gas species, such as a fluorine-containing species in a gas containing same, e.g., an effluent of a semiconductor processing tool undergoing etch cleaning with HF, NF3, etc. The gas detector in one aspect employs a nickel-containing filament that is sensitive to the fluorine-containing species, which can function both as a sensing component and as a heat source when elevated temperature sensing is required. The gas detector in one aspect employs an elongated gas sensor element that can be vertically mounted on a support structure. Vertical mounting of such elongated gas sensor element on the support structure significantly improves the signal strength, reduces the response time, minimizes the footprint of the gas detector, and provides structural flexibility for accommodating thermal expansion/contraction of such gas sensor element.
    • 一种气体检测器和用于检测目标气体种类的气体检测器和方法,所述目标气体种类例如含有气体的气体含有气体,例如用HF,NF3等进行蚀刻清洗的半导体加工工具的流出物。气体检测器在一个方面 采用对含氟物质敏感的含镍灯丝,当需要高温感应时,该含氟灯丝既可用作传感元件又可用作热源。 气体检测器在一个方面采用可以垂直安装在支撑结构上的细长的气体传感器元件。 这种细长的气体传感器元件在支撑结构上的垂直安装显着提高了信号强度,减少了响应时间,使气体检测器的占用面积最小,并且提供了适应这种气体传感器元件的热膨胀/收缩的结构灵活性。
