Claim 0:
1. A method for manufacturing an optoelectronic device, comprising:
forming a first layer of light-transmissive material over a photodiode array, the photodiode array including a plurality of photodiodes, each photodiode having a respective n-well region;
forming a plurality of first trenches in the first layer of light-transmissive material;
forming a layer of light-blocking material in the plurality of first trenches;
forming a first metal layer over the first layer of light-transmissive material and the layer of light-blocking material;
forming a second layer of light-transmissive material over the first metal layer;
forming a plurality of second trenches in the second layer of light-transmissive material, each of the second trenches having a different depth;
forming a respective second metal layer in each of the plurality of second trenches; and
filling each of the second trenches with a light-transmissive material after the respective second trench's respective second metal layer is formed in the second trench.
