| Zusammenfassung: | A method of forming a semiconductor device, where the method includes receiving a substrate in a processing chamber, the substrate including a first patterned layer including a metal-based material; and with a gaseous etch process, trimming the first patterned layer to form a second patterned layer, the gaseous etch process including exposing the first patterned layer to an un-ionized gas including a halogen compound. |
