摘要: A method for forming a rough silicon wafer including the successive steps of: performing a plasma etching of a surface of the wafer in conditions suitable to obtain a rough structure, and performing two successive ion milling steps, one at an incidence in the range of 0 to 10°, the other at an incidence in the range of 40 to 60° relative to the normal to the wafer.
