Generally, in some examples, a wet etch process for removing a capping layer can form a first monolayer on the underlying layer as an adhesion layer and a second monolayer on, e.g., an interfacial dielectric layer between a gate spacer and a fin as an etch protection mechanism. Generally, in some examples, a wet process can form a monolayer on a metal layer, like a barrier layer of a work function tuning layer, as a hardmask for patterning of the metal layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Metal gate using monolayers","description":"Methods for, and structures formed by, wet process assisted approaches implemented in a replacement gate process are provided.
