摘要： A DC sputtering system improved in prevention of fusion of a substrate and electric corrosion of a pallet revolving shaft due to the flow of negative electric charges at the time of production of an optical disk. The system includes a pair of electrodes, a negative electrode and a positive electrode, wherein the negative electrode is composed of a target plate made from a target material such as Si and a backing plate on which the target plate is fixedly placed, and the positive electrode is composed of a pallet disposed opposite to the negative electrode. A substrate of an optical disk is mounted on the positive electrode side through a disk base using an inner peripheral mask and an outer peripheral mask. Each of the inner peripheral mask and the outer peripheral mask is made from or covered with an electrically insulating material such as teflon or ceramic. This prevents the flow of negative electric chargers from being concentrated at the inner peripheral mask and the outer peripheral mask, to thereby protect the substrate from being fused.
摘要翻译： DC溅射系统由于在制造光盘时的负电荷的流动而改进了防止基板熔化和托盘旋转轴的电腐蚀。该系统包括一对电极，负极和正极，其中负极由目标材料如Si制成的目标板和固定放置目标板的背板构成，正极电极由与负极相对设置的托盘组成。使用内周掩模和外周掩模，通过盘基座将光盘的基板安装在正极侧。内周边罩和外周罩均由电绝缘材料制成或覆盖，如聚四氟乙烯或陶瓷。这防止负电荷充电器的流动集中在内周掩模和外周掩模上，从而保护基板不熔化。
