Apparatuses and methods for determining if protective coatings on semiconductor substrate holding devices have been compromised

An apparatus configured to determine if a protective coating on a semiconductor substrate receiving device has been compromised, comprising:

• the semiconductor substrate receiving device, the device having at least one extension configured to hold a semiconductor substrate within a liquid bath, the device being configured to have at least a portion of the extension at least periodically within the liquid bath, the extension comprising a conductive material at least partially coated with an insulative protective material, the insulative protective material being configured to protect the portion of the conductive material which is in the bath from physically contacting the liquid of the bath;
• an electrode within the bath;
• an electrical connection between the electrode and the conductive material of the extension, and
• a monitor configured to monitor a current flow state of a circuit comprising the electrode, conductive material of the extension, and liquid bath to determine if the circuit is in a closed state or in an open state;
• the state of the circuit being different if the protective material is compromised than if the protective material is not compromised.

An apparatus configured to determine if a protective coating on the semiconductor substrate lifting device has been compromised, comprising:

• the semiconductor substrate lifting device, the device having at least one extension configured to move a semiconductor substrate relative to a liquid bath, the device being configured to periodically place at least a portion of the extension within the liquid bath, the extension comprising a conductive material at least partially coated with an insulative protective material, the insulative protective material being configured to protect the portion of the conductive material which is periodically placed in the bath from physically contacting the liquid of the bath;
• an electrode within the bath;
• an electrical connection between the electrode and the conductive material of the extension;
• and
• a monitor configured to monitor a circuit comprising the electrode, conductive material of the extension, and liquid bath to determine if the circuit is closed and enables a predetermined current flow or open and does not enable the predetermined current flow;
• the circuit being open unless the protective material is sufficiently compromised.
