Abstract
A notched-spacer camera module includes a chip-scale package, a lens plate, a spacer ring, and a glue ring. The chip-scale package has an image sensor and a top surface. The spacer ring includes a glue gate having a gate height and a spacer base, having a base height, between the glue gate and the lens plate. The glue ring is between the spacer ring and the top surface and has (i) an outer region between the top surface and a bottom surface of the spacer base, and (ii) an inner region, having an inner thickness, between the top surface and a bottom surface of the glue gate. The lens plate, the spacer ring, the glue ring, and the top surface form a sealed cavity having a cavity height equal to at least a sum of the inner thickness, the gate height, and the base height.
