  • Publication number: 20240167188
    Abstract: The present disclosure relates to an electroplating system including a first contact detection sensor and a second contact detection sensor disposed at a surface of a cone of the electroplating system. The first contact detection sensor detects a first resistance at a first contact between a substrate to be plated by the electroplating system and a first contact pin, the second contact detection sensor detects a second resistance at a second contact between the substrate and a second contact pin. A controller receives the first resistance and the second resistance, and determines the first contact and the second contact are not properly formed when a difference between the first resistance and the second resistance is not within a first predetermined resistance range, or the first resistance or the second resistance is not within a second predetermined resistance range.
