Optical module for a camera device, baffle substrate, wafer scale package, and manufacturing methods therefor

Baffle substrate with a plurality of baffles, comprising:

• a generally transparent substrate having a front surface and a rear surface,
• a generally non-transparent first layer with a plurality of second openings on the front surface,
• a generally non-transparent second layer with a plurality of second openings on the rear surface, and
• further comprising a plurality of lens elements arranged on at least one of the front surface and the rear surface of the baffle substrate portion in the region of the second openings.

Method for manufacturing a plurality of optical modules, comprising the following steps:

• Providing a generally transparent baffle substrate having a front surface and a rear surface, a generally non-transparent first layer with a plurality of first openings on the front surface and a generally non-transparent second layer with a plurality of second openings on the rear surface;
• attaching a plurality of top lens elements to the at least one of the front surface and the rear surface of the baffle substrate in the regions of the first or second openings;
• providing at least one additional substrate;
• stacking and connecting the substrates;
• dicing the package formed in the step of stacking and connecting the substrates along predetermined planes.
