Abstract
An image sensor includes photosensitive areas in a first array within a semiconductor substrate. Microlens are disposed over the semiconductor substrate in a second array. Metal shields are disposed between a subset of the microlenses and corresponding photosensitive areas. The metal half-shields have dimensions and positions that provide half-shielding that enables half-shield phase detection autofocus. An antireflective coating is disposed over the metal half-shields. The metal half-shields and the antireflective coating may be in a composite grid that provides lateral separation between color filters. Alternatively, metal half-shields and the antireflective coating may be in below a layer that includes color filters. The antireflective coating includes a quarter-wave layer.
