What Does an Electrostatic Chuck Do? Its Working Principle Explained!
In advanced manufacturing fields such as semiconductor fabrication, flat-panel displays, and precision optics, one seemingly modest device directly affects product precision and yield —— the electrostatic chuck (Electrostatic Chuck, abbreviated ESC). Its core function is to secure workpieces without contact using electrostatic force, replacing traditional mechanical fixtures and acting as an “invisible hand” in micron- and even nanometer-scale precision processing.
