Wafer level image module, method for making the same and apparatus for assembling and testing the same

摘要

A wafer level image module (10) includes a photo sensor (20) for outputting an electrical signal upon receiving light, a lens set (30) for focusing incident light onto the photo sensor (20), and an adjustment member (25) disposed between the photo sensor (20) and the lens set (30) for controlling the distance between the photo sensor (20) and the lens set (30) to compensate the focus offset of the photo sensor for enabling the lens set to accurately focus the incident light onto the photo sensor in an in-focus manner so as to provide a high image quality.
