    摘要: Apparatus for chemically etching a workpiece includes a chamber for receiving a process gas and having a pumping port for extracting exhaust gases, and a workpiece support located in the chamber upstream of the pumping port. The chamber further includes a sub-chamber located upstream of the pumping port and downstream of the workpiece support, and the sub-chamber includes a window and an excitation source, adjacent the window, for creating a plasma in a sample of the exhaust gases to create an optical emission which can be monitored through the window.

    摘要: A wideband variable impedance load for high volume manufacturing qualification and diagnostic testing of a radio frequency power source, an impedance matching network and RF sensors for generating plasma in a semiconductor plasma chamber for semiconductor fabrication processes. The wideband variable impedance load may comprise a fixed value resistance operable at a plurality of frequencies and coupled with a variable impedance network capable of transforming the fixed value resistance into a wide range of complex impedances at the plurality of frequencies. Response times and match tuning element position repeatability may be verified. Automatic testing, verification and qualification of production and field installed radio frequency power sources for plasma generation are easily performed.

    摘要: A plasma sensor module may include an upper substrate, a lower substrate, at least one probe and a printed circuit board (PCB). The upper substrate may be configured to be exposed to plasma. The lower substrate may contact a lower surface of the upper substrate. The lower substrate may have a thickness that is thicker than a thickness of the upper substrate. The probe may be in the lower substrate. The PCB may be in the lower substrate. The PCB may be configured to apply an alternating current to the probe to detect a density of the plasma. Thus, the structural strength of the plasma sensor module may have improved structural strength.
