The etchant gas includes PF3 and at least one oxidizing agent, such as at least one of oxygen, ozone, nitrous oxide, nitric oxide and hydrogen peroxide. The etchant gas provides a method of uniformly removing the late transition metal structure or a portion thereof. Moreover, the etchant gas facilitates removing a late transition metal structure with an increased etch rate and at a decreased etch temperature. A method of removing a late transition metal without removing more reactive materials proximate the late transition metal and exposed to the etchant gas is also disclosed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Etchant gas","description":"An etchant gas and a method for removing at least a portion of a late transition metal structure.
