摘要: This disclosure describes systems, methods, and apparatus for a plasma processing system. A method comprises receiving a reference signal defining target values for a parameter that is controlled at an output within the plasma processing system, obtaining a measure of the parameter that is controlled at the output, and calculating a delay between the target values of the setpoint signal and corresponding actual parameter values achieved at the output. The method also comprises providing, based upon the delay, a time-shifted amplitude error indicative of an error between the target values and the actual parameter values and adjusting at least one actuator, based upon the delay and the time-shifted amplitude error, in advance of when an actual parameter value is desired at an actuator output of the at least one actuator while maintaining the output within a threshold range.

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.

摘要: The invention relates to a method and to a device for the in situ determination of the surface characteristics of conductive targets. The method according to the invention makes it possible to measure the energy distribution and angle distribution of the hydrogen or deuterium atoms scattered at a metal surface. From the Doppler shift of the blue- and red-shifted components of the induced Balmer lines, the spectral or specular reflectivity of the surface can be directly measured. Furthermore, the mass of the atoms at the surface of the target can be determined.
