Lam, Novellus take two paths to strip wafer edges

09/11/2007  Silicon wafer edges induce inherent non-uniformities in processing, and also seem to be the main source of defects for immersion lithography. Cleaning/stripping the wafer edge (or "bevel") is thus essential for production yield. Here follows a tale of two companies, two machines, and two different ways to solve the edge problem by dry stripping.
