Abstract:
Disclosed are a CMOS image sensor encapsulation structure and a method for manufacturing the same, including the steps of: firstly, a transparent substrate material is fixed to a surface of a first insulating layer having a micro convex lens, a dummy wafer is fixed on a surface of the transparent substrate material, and then a wafer is thinned by grinding, and in this process, the transparent substrate material provides more mechanical support force for the wafer, therefore, the wafer can become thinner by grinding, thus the CMOS image sensor encapsulation structure is characterized by being formed in a thin shape. Besides, a second installation area has a protection glue layer which can prevent oxygen and moisture from entering internal elements and absorb scattered light.
