摘要:
A plasma boat for receiving wafers with partial damping of the plasma deposition comprises a number of boat plates spaced apart in parallel, which are provided with wafer holders for receiving upright wafers, in order to securely hold the wafers during transport and during the depositing process in a coating chamber, and wherein the boat plates are mechanically connected to one another by electrically insulating spacers. This provides a plasma boat, with regulated plasma deposition, which ensures a deposition on wafers that is uniform over the surface area thereof and has a constant layer thickness. This is achieved by a damping element (12) being respectively arranged between the wafer holders (16) located parallel to one another, between adjacent boat plates (15), and electrically insulated with respect to the latter on spacer elements (2).
