The method described herein includes generating fluorine radicals and ions, delivering the fluorine radicals through an ion blocker to a processing region, and removing one or more portions of a gate structure to expose one or more portions of a gate dielectric material disposed thereunder. The gate structure includes at least two ceramic or metal layers, and the gate dielectric material is made of a high-k dielectric material. A substrate having the gate structure and gate dielectric material formed thereon is disposed in the processing region, and the temperature of the substrate is maintained at about 60 degrees Celsius or higher. By etching the gate structure using fluorine radicals at a temperature greater or equal to 60 degrees Celsius, the at least two ceramic or metal layers have a flat cross sectional profile."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"HKMG integration","description":"A method for processing a semiconductor substrate is described herein.
