A first gate structure is on the semiconductor substrate overlying the first conductivity type region. A second conductivity type region including a second conductivity type impurity is formed in the semiconductor substrate. A barrier layer is located between the first conductivity type region and the second conductivity type region. The barrier layer prevents diffusion of the second conductivity type impurity from the second conductivity type region into the first conductivity type region."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Semiconductor device having barrier layer to prevent impurity diffusion","description":"A semiconductor device includes a semiconductor substrate having a first conductivity type region including a first conductivity type impurity.
