Substrate holder for vertical galvanic metal deposition

Substrate holder for vertical galvanic metal deposition on a substrate to be treated comprising a first substrate holder part and a second substrate holder part, wherein both substrate holder parts comprise an inner metal comprising part and an outer non-metallic part characterized in that the substrate holder further comprises

• i) At least one hanging element in each substrate holder part for mechanically connecting the substrate holder to a treatment container,
• ii) At least one first sealing element in each substrate holder part arranged between the substrate to be treated and the respective substrate holder part,
• iii) At least one second sealing element for the entire substrate holder arranged between the inner metal comprising part of the substrate holder and the outer non-metallic part of the substrate holder,
• iv) At least one fastening system for detachably fastening both substrate holder parts to each other for holding the substrate to be treated,
• v) At least one first contact element in each substrate holder part for forwarding current from an outer source through the hanging element to the at least one second contact element, and
• vi) At least one second contact element in each substrate holder part for forwarding current from the at least first contact element to the substrate to be treated.
