    摘要: A configuration for measuring the concentration of contaminating particles at high time resolution in the mini environments of loading and unloading chambers of processing appliances in semiconductor fabrication includes a probe, a movement unit for the probe, a particle detector, vacuum pump and a control unit. Reaching critical layer thicknesses of disk carriers or boats in ovens, and maladjustments of handling systems for wafers, masks, flat panel displays and other disc-like objects can be detected in terms of the cause and quantified immediately. The movement unit moves the probe to a desired position in the loading and unloading chamber as a reaction to the positioning of the handling system. A method of operating the configuration is also provided.
