Lenses and methods of manufacturing the same

A method, comprising:

• forming a masking layer over a medium configured to transit incoming light toward a light sensor;
• and
• patterning a top surface of the medium, using the masking layer, to include a plurality of holes,
• wherein the plurality of holes are configured to direct the incoming light toward a plurality of focal points associated with a top surface of the light sensor.

A semiconductor device, comprising:

• a light sensor configured to convert incoming light to electrical signals;
• a medium configured to transit the incoming light toward the light sensor;
• and
• a set of holes on a top surface of the medium, opposite the light sensor, comprising:
• a first subset of holes, having a first opening, that are arranged over a plurality of focal points associated with a top surface of the light sensor;
• and
• a second subset of holes, having a second opening smaller than the first opening, that approximately surround the first subset of holes in a plurality of circular patterns.
