Zusammenfassung:Apparatus, devices, and methods for increasing the ion energy in a plasma processing devices are provided. In various embodiments, the surface area of a showerhead facing the work piece includes a plurality of features. The plurality of features increases the surface area of the showerhead relative to a flat surface. Increasing the surface area of the showerhead increases the ion energy without increasing the power used to generate the plasma. Increasing the ion energy using such a showerhead allows for the broader application of plasma processes in integrated circuit manufacturing.
