    • PROBLEM TO BE SOLVED: To generate and adjust plasma so that the plasma can contribute to uniform plasma treatment in simultaneous and continuous treatment of combining vapor deposition with etching; and to provide the uniform plasma treatment capable of coating a substrate having a high aspect ratio by using an iPVD technique.
      SOLUTION: The uniformity of a plasma distribution having a tendency to peak toward the axis of a processing chamber is improved by positioning a hollow body on the chamber axis with an open end facing the processing space. The hollow body controls the distribution of the plasma away from the center and allows the plasma at the center. The geometry of the hollow body can be optimized to render the plasma uniform for given conditions. In combined deposition and etch processes, such as simultaneous and sequential etch and iPVD processes, the hollow body provides for a uniform plasma for etching while allowing deposition parameters to be optimized for deposition.

    • 要解决的问题:产生和调整等离子体,使得等离子体有助于均匀等离子体处理,同时并连续地处理气相沉积与蚀刻; 并且通过使用iPVD技术提供能够涂覆具有高纵横比的基板的均匀等离子体处理。 解决方案:通过将空心体定位在室轴线上,面向处理空间的开口端,改善了具有朝向处理室轴线倾向的等离子体分布的均匀性。 中空体控制等离子体离开中心的分布,并允许等离子体在中心。 可以优化空心体的几何形状以使给定条件下的等离子体均匀。 在组合沉积和蚀刻工艺中,例如同步和顺序蚀刻和iPVD工艺,中空体为蚀刻提供均匀的等离子体,同时允许为沉积而优化沉积参数。 版权所有(C)2007,JPO&INPIT
