Abstract

Abstract Translated from Japanese 【課題】「混色」の発生などを防止して、撮像画像の画像品質を向上させる。 【解決手段】第1トレンチTR1と、半導体基板101において第1トレンチよりも浅い部分において、第1トレンチTR1よりも幅が広い第2トレンチTR2とを、トレンチTRとして形成する。そして、第1トレンチTR1の内部を埋め込むと共に、第2トレンチTR2の内側の面を被覆するようにピニング層311を形成する。そして、少なくともピニング層311を介して第2トレンチTR2の内部を埋め込むように、遮光層313を形成する。 【選択図】図3 An image quality of a captured image is improved by preventing the occurrence of “color mixing”. A first trench TR1 and a second trench TR2 having a width wider than the first trench TR1 are formed as a trench TR in a portion shallower than the first trench in the semiconductor substrate 101. Then, the pinning layer 311 is formed so as to fill the inside of the first trench TR1 and cover the inner surface of the second trench TR2. Then, the light shielding layer 313 is formed so as to fill the inside of the second trench TR2 via at least the pinning layer 311. [Selection] Figure 3
