A work function layer is formed on the semiconductor substrate. A buffer layer is formed on the work function layer. The work function layer is doped through the buffer layer with impurity ions. The buffer layer obstructs a flow of the impurity ions to control a concentration of the impurity ions in different regions of the work function layer to regulate a work function of the work function layer in the different regions."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device and fabrication method thereof","description":"The present disclosure provides semiconductor devices and fabrication methods thereof.
