Description

technical field [0001] The invention relates to a calibration assembly of an electrostatic voltmeter, its manufacturing method and its calibration method, in particular to a static voltmeter calibration assembly with a structure of coarse adjustment and fine adjustment, which can accurately calibrate the static voltmeter. Background technique [0002] In the current semiconductor industry, the main purpose of electrostatic protection is the following four points: [0003] (1) Increased yield (Increased Yields): If the electrostatic protection is not good, it is likely that the components will be damaged due to the influence of static electricity during the production of semiconductor components. Moreover, in every process, there is the possibility of electrostatic damage. Therefore, proper electrostatic protection can increase production. [0004] (2) Cost Saving: Due to the high process yield of semiconductor components, the relative process cost can be reduced. Therefor...

Problems solved by technology

The traditional static voltmeter calibration method is only a simple manual calibration method, and there is no more accurate calibration method to calibrate the static voltmeter

If the calibration accuracy is low, it may be due to the inaccurate measurement of the static voltage meter, resulting in the continuous accumulation of static electricity in the process machine, which may eventually lead to the destruction of the manufactured semiconductor components due to excessive static electricity.
