The common structured stack includes a work-function metal layer, and a barrier layer. The barrier layer of the first instance of the common structured stack is etched through, and the work-function metal layer of the first instance of the common structure is partially etched. The partial etch forms a thinner work-function metal layer, having an oxide of the work-function metal as a new barrier layer. A gate element is formed on the new barrier layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus of multi threshold voltage CMOS","description":"A first and a second instance of a common structured stack are formed, respectively, on a first fin and a second fin.
