Atmospheric process and system for controlled and rapid removal of polymers from high depth to width aspect ratio holes
A hot arc-type plasma generating system is described to etch a polymer on a substrate used in the manufacture of semiconductor devices. The etching process is particularly useful to remove a polymer from high aspect ratio holes, that can include trenches, greater than about 10 to 1 and even greater...

| Zusammenfassung: | A hot arc-type plasma generating system is described to etch a polymer on a substrate used in the manufacture of semiconductor devices. The etching process is particularly useful to remove a polymer from high aspect ratio holes, that can include trenches, greater than about 10 to 1 and even greater than 50 to 1. |
