IMAGING ARRAYS HAVING FOCAL PLANE PHASE DETECTING PIXEL SENSORS AND METHODS FOR PERFORMING FOCAL PLANE PHASE DETECTION IN IMAGING ARRAYS

摘要

A focal plane phase detect pixel sensor is formed on a substrate and includes a surface pixel sensor formed in a pixel sensor area at a surface of the substrate. The surface pixel sensor has a sensing area occupying no more than an adjacent pair of quadrants centered in the pixel sensor area. A microlens is disposed over the surface pixel sensor.
