These isolation regions may prevent cross-talk and improve the performance of the image sensor. The isolation regions may include a conductive layer that is electrically connected to a bias voltage supply line. Biasing the conductive layer may result in a charge inversion in the substrate adjacent to the conductive layer. The charge inversion may prevent the generation of dark current. The conductive layer may be formed on a liner oxide layer in trenches formed in epitaxial silicon. A connecting layer may be used to electrically connect each conductive layer. The connecting layer may be formed integrally with the conductive layer or formed from a separate material."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pixel isolation regions formed with conductive layers","description":"An image sensor may include isolation regions that are formed in between photodiodes.
