IMAGE SENSOR

To provide an image sensor capable of realizing clear image quality.SOLUTION: The invention provides a substrate having a first surface and a second surface, which are opposite to each other, and microlenses on the second surface. Interconnection lines on the first surface and a pixel isolation portion in the substrate are included, where the pixel isolation portion isolates pixels from each other. The pixel isolation portion includes an insulating isolation pattern and a conductive pattern, where the conductive pattern is separated from the substrate across the insulating isolation pattern. The conductive pattern includes a first conductive pattern, a second conductive pattern and a third conductive pattern that are sequentially provided on a side wall of the insulating isolation pattern.SELECTED DRAWING: Figure 5A 【課題】鮮明な画質を具現化することができるイメージセンサーを提供する。【解決手段】第１面とこれに反対になる第２面を有する基板、及び前記第２面上のマイクロレンズが提供される。前記第１面上の配線及び前記基板内に配置され画素を互いに分離させる画素分離部を含む。前記画素分離部は分離絶縁パターン及び前記分離絶縁パターンを介して前記基板と離隔される導電パターンを含む。前記導電パターンは前記分離絶縁パターンの側壁上に順に提供される第１導電パターン、第２導電パターン、及び第３導電パターンを含む。【選択図】図５Ａ
