The method further includes removing the first masking material and the second masking material until the workfunction material is exposed over the second device area."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Patterning scheme to minimize dry/wets strip induced device degradation","description":"A patterning scheme to minimize dry/wet strip induced device degradation and resultant devices are provided.
