Claim 0:
1. An electroplating system, comprising:
an electroplating chamber configured to hold a plating bath;
a substrate holder configured to hold a substrate to be plated by the plating bath, wherein the substrate holder includes a first contact pin and a second contact pin, and wherein the first contact pin and the second contact pin are configured to receive power supplied to the substrate during electroplating; and
a cone configured to load the substrate onto the substrate holder, wherein the cone comprises a first contact detection sensor and a second contact detection sensor disposed on a surface of the cone, wherein when the cone is in a closed position, a first contact is formed between the substrate and the first contact pin and a second contact is formed between the substrate and the second contact pin, and wherein the first and second contact detection sensors are disposed vertically above the first and second contact pins, respectively, and are configured to detect first and second resistances of the first and second contacts, respectively.
