| description | The invention relates to a plate element for a wafer boat for the plasma treatment of disk-shaped wafers, in particular semiconductor wafers for semiconductor or photovoltaic applications. The plate element is electrically conductive and has at least one holding unit on each side, for holding a wafer in a wafer holding region. The plate element has at least one recess in at least one side of the plate element and/or at least one opening in the plate element, wherein the at least one recess and/or the at least one opening in the plate element lies at least partially radially outside of the wafer holding region and directly adjacent thereto. The invention further relates to a wafer boat that has a plurality of plate elements of the above type arranged parallel to each other, wherein plate elements arranged adjacent are electrically insulated from each other. The invention further relates to a wafer boat in combination with a plasma treatment device, which has a process chamber for accommodating the wafer boat, |
