Camera module manufacturing method and camera module

This invention describes a method for manufacturing compact camera modules, such as those found in smartphones. It integrates light control directly into the lens structure by forming a light-blocking layer on the sides of the lenses and their support components. This layer acts as both a diaphragm to regulate incoming light and a shield against stray light, eliminating the need for separate parts and simplifying the module. The method involves preparing image sensor wafers and lens arrays.
