    • A system is provided for etching patterned media disks for hard drive. The modular system may be tailored to perform specific processes sequences so that a patterned media disk is fabricated without removing the disk from vacuum environment. In some sequence the magnetic stack is etched while in other the etch is performed prior to forming the magnetic stack. In a further sequence ion implantation is used without etching steps. For etching a movable non-contact electrode is utilized to perform sputter etch. The cathode moves to near contact distance to, but not contacting, the substrate so as to couple RF energy to the disk. The substrate is held vertically in a carrier and both sides are etched serially. That is, one side is etched in one chamber and then in the next chamber the second side is etched.
    • 提供了用于蚀刻用于硬盘驱动器的图案化介质盘的系统。 模块化系统可以被定制以执行特定的处理顺序,使得图案化的介质盘被制造而不从真空环境中移除盘。 在一些顺序中,磁性堆叠被蚀刻,而另一些蚀刻则在形成磁性堆叠之前进行。 在另外的序列中,使用离子注入而没有蚀刻步骤。 为了蚀刻可移动的非接触电极用于进行溅射蚀刻。 阴极移动到与衬底接近但不接触的接近距离,以将RF能量耦合到盘。 衬底垂直地保持在载体中,并且两侧被连续蚀刻。 也就是说,在一个室中蚀刻一面,然后在下一个室中蚀刻第二面。
