What it is
General reference — not yet source-verifiedThe Lam Research 4520 XLE is an etching system used in semiconductor manufacturing. Etchers remove material from the surface of a wafer, typically through chemical or plasma processes.
Where it fits in the process flow
General reference — not yet source-verifiedIn a semiconductor fabrication line, the etching step is often performed after cleaning and before thin-film deposition or as a dry-etch step during lithographic pattern transfer. The etcher can be used to remove native oxides, roughen surfaces for adhesion, or selectively etch layers through a mask.
