Abstract
The dry etch rates in Ta2O5 were enhanced by using ultraviolet (UV) light irradiation during inductively coupled plasma (ICP) etching. The material was etched both in SF6/Ar and Cl2/Ar plasma chemistries. The increased in etch rates are assumed to be due to the photoassisted desorption of the TaClx and TaFx etch products.
