Abstract: A carriage motor is driven with a predetermined duty value and it is determined whether a carriage is moved. If it is determined that the carriage is moved, a lower duty value is set. If it is determined that the carriage is not moved, a higher duty value is set, in order to obtain the duty values at the time when the carriage is and is not moved. The duty values when the carriage is moved and is not moved, are stored, as alternative characteristic values, in an EEPROM in association with positional information of duty value detection position. Therefore, quality control may be properly performed by checking the stored duty values.

Abstract: Processing parameters of at least one plate-shaped object, e.g. a semiconductor device or wafer, or a flat panel display, in a processing tool are adjusted depending on which processing device out of at least one set of processing devices has been used for the semiconductor device in a preceding step. A virtual or physical tag is generated, which connects the semiconductor device identification with the processing device identification. This enables a compensation of tool-dependent effects in previous processing of a single device. An example is chemical mechanical polishing prior to lithography, where alignment marks can be deteriorated differently between CMP-units. The amount of compensation is detected and evaluated by metrology tools, which—depending on the sequence of the metrology step relative to the processing step to be adjusted—either feed-forward or feed-backward their results to the processing tool. The yield of semiconductor device production is advantageously increased.

Abstract: The invention relates to a method and a device for monitoring an area of coverage around a working tool with the aid of at least one camera. In a first method step, an object-free security zone within the area of coverage is recorded with the camera as reference background. Subsequently, the reference background is checked with respect to its non-homogeneity. In the process, the reference background is rejected as non-valid only if within a predetermined variance distance, the detected non-homogeneity falls below a predetermined level. Otherwise, the reference background is classified as valid. If the reference background is classified as valid, the detection of safety-critical objects entering the security zone is released. The detection occurs through a comparison of the actual images of the security zone recorded with the camera and the valid reference background. A safety-critical object is considered recognized if the respective actual image deviates significantly from the reference background.
