摘要: A method, a non-transitory computer readable medium and a device. The method may include (a) introducing a voltage difference between an absolute value of a negative pole of the electrostatic chuck and an absolute value of a positive pole of the electrostatic chuck, the introducing occurs while the wafer is supported by the electrostatic chuck and is contacted by one or more conductive contact pins of the electrostatic chuck; (b) monitoring, by an electrostatic sensor that comprises a sensing element, a charge at a point of measurement located at a front side of the wafer, at different points of time that follow a start of the introducing of the voltage difference, to provide monitoring results; and (c) determining an electrical parameter of the contact between the wafer and the electrostatic chuck, based on the monitoring results.

摘要: A computer program product and a method for dissipation of an electrical charge stored in a region of an object. The method may include (a) sensing, by at least one sensor, an electrical charging status of the region of the object, while the object is located within a vacuum chamber and while a gaseous pressure within the vacuum chamber is below a certain vacuum pressure threshold; and (b) performing, based on the charging status of the given region, an electrical charge dissipation process that comprises increasing the gaseous pressure within the vacuum chamber to be within a given gaseous pressure range that facilitates a dissipation, by breakdown, of the electrical charge stored in the region of the object to the vacuum chamber.

摘要: A cleanliness monitor, an evaluation system and a method. The cleanliness monitor may include: a first vacuum chamber, a second vacuum chamber, a molecule collector, a release unit, a mass spectrometer, a manipulator that may be configured to move the molecule collector from the first position to the second position, and an analyzer. The mass spectrometer may have a line of sight to an inner space of the second vacuum chamber. The mass spectrometer may be configured to monitor the inner space of the second vacuum chamber and to generate detection signals that are indicative of a content of the inner space of the second vacuum chamber. A first subset of the detection signals may be indicative of a presence of the at least subset of released organic molecules. The analyzer may be configured to determine, based on the detection signals, the cleanliness of at least one out of (a) the first vacuum chamber, and (b) a tested vacuum chamber. The tested vacuum chamber is fluidly coupled to the first vacuum chamber.

摘要: A cleanliness monitor for monitoring a cleanliness of a vacuum chamber. The cleanliness monitor may include a mass spectrometer, a molecule aggregation and release unit and an analyzer. The molecule aggregation and release unit is configured to (a) aggregate, during an aggregation period, organic molecules that are present in the vacuum chamber and (b) induce, during a release period, a release of a subset of the organic molecules towards the mass spectrometer. The mass spectrometer is configured to monitor an environment within the vacuum chamber and to generate detection signals indicative of a content of the environment; wherein a first subset of the detection signals is indicative of a presence of the subset of the organic molecules. The analyzer is configured to determine the cleanliness of the vacuum chamber based on the detection signals.
